Agents

Grok Bot is a team of AI teammates, each on its own cloud computer, coordinated by a chief-of-staff agent.

It began as an internal SpaceX tool and passed 400,000 weekly users within a month of its August launch. The bots work in tools without clean APIs or MCP, can learn a task by watching it and save it as a routine, keep memory across conversations and run in parallel. The beta is limited to SuperGrok Heavy and Cursor Ultra subscribers after SpaceX's $60B acquisition of Cursor.

Muse is Meta's personal agent that researches, fills forms, shops, books and negotiates bills and subscriptions for you.

Muse reached 5 million downloads in three weeks and hit #1 on the US App Store, pushed by up to half of Meta's own daily ad inventory. Its early traction came from personal finance: chasing refunds, cancelling subscriptions, finding cheaper car insurance and cancelling the old policy. It connects to email, calendar, Instagram and OpenTable, asks approval before sensitive actions, and pays through Stripe Link's one-time cards.

Dots are always-on background agents in ChatGPT, each with its own cloud computer, connected to 4,000+ apps.

Launched at DevDay a day after Meta's Muse, Dots run on GPT-6 Astra and are reachable from ChatGPT, Slack and Teams with shared context. Idle agents do proactive, read-only research for ways to help, and anything touching an account goes through an auto-review check. One agent is included with Pro ($100/month) and Business Premium, with specialist agents that have their own identity and credentials in enterprise beta.

Comet is an agentic browser that researches, compares, books and fills forms across tabs on your behalf, built on Perplexity's answer engine.

Perplexity took the answer engine into the browser: Comet grew from about 3 million to an estimated 18 million monthly users in the first quarter of 2026 and the core product has about 45 million monthly users. ARR passed $750M by August 2026 on a mix of Pro subscriptions, enterprise seats and a growing ads and commerce business. It raised at a $20B valuation in September 2025 and was in talks with Nvidia for a round above $30B in August 2026.

A personal agent you text on iMessage or WhatsApp that books, buys, cancels and calls on your behalf with its own email, browser and phone.

Fourteen people, a $10B valuation and $1B+ of annual transaction volume before public release: the valuation went from about $50M to $10B in five months. It keeps credentials in a vault, pays with one-time Stripe Link cards, and runs a 'Trusted Person' network where users' agents coordinate with each other. The product is still invite-only and free.

Super Agent turns a plain-language request into a finished deliverable, from a slide deck or spreadsheet to a phone call it makes for you.

Genspark is the breakout prosumer agent: over 2 million monthly active users and an estimated 100,000 paying seats within a year of launch, and it reported $36M in ARR just 45 days after Super Agent shipped in 2025. Founded by former Baidu search executives, it orchestrates a mix of nine models and 80 tools rather than one model. It raised more than $200M in a November 2025 Series B at a $1B valuation.

A swipeless dating app where a voice agent interviews you for about 20 minutes, then makes one introduction at a time and plans the first date.

There are no profiles, no swiping and no in-app chat: matches get 24 hours to accept and 24 hours to agree a date, and the agent picks the venue. Sixty percent of introductions are accepted and thousands of dates have been scheduled across the Bay Area and San Diego. It charges $15 per date instead of a subscription, which Known says cuts no-shows. Two Stanford dropouts raised $10M from Forerunner and NFX.

Fo is a personal agent on iMessage, WhatsApp or the web that researches, calls, emails, books and pays with single-use virtual cards.

Fo has its own phone number, email address and patented single-use cards, and when it gets stuck a trained human assistant steps in, which is why it is reliable enough for jobs like finding a plumber, getting quotes and scheduling the visit. It runs in isolated encrypted compute and only calls whitelisted contacts. Tens of thousands of users in 107 countries, doubling every two days after the late-September launch; Khosla Ventures and Jeff Dean back it.

Claude Code is an agentic coding tool that lives in the terminal, reads a whole codebase, runs commands and ships multi-file changes on its own.

The fastest-growing developer product of the agent era: Claude Code passed $1B in annualized revenue within six months of its mid-2025 launch and $2.5B by February 2026, and business subscriptions quadrupled in the first months of 2026. It is the engine behind many of the other agents on this list, since most of them run on Claude models. Anthropic's run-rate revenue passed $47B in May 2026 and the company filed confidentially for an IPO on June 1 at a $965B valuation.

Agentforce builds and runs autonomous service, sales and marketing agents on top of a company's Salesforce data.

The largest enterprise agent business by disclosed revenue: Agentforce ARR hit $1.2B in the quarter ended April 2026, up 205% year over year, and Agentforce plus Data 360 passed $3.4B. Salesforce closed more than 18,500 Agentforce deals in its first year and runs the agents inside the CRM, so they can act on customer records rather than just answer questions. It is the clearest example of an incumbent turning agents into a reported revenue line.

Link's agent wallet lets an AI agent request a purchase, the user approve it, and a one-time virtual card pay for it.

The agent never sees the real card: each request is scoped by merchant, amount and description, issued as a one-time card or Shared Payment Token, and revocable like an OAuth grant. Agentic purchases through Link rose 38x in a month, with purchase protection for loss, theft and price drops. Muse, Instinct and Town all check out through it, which makes Stripe the payments layer of the agent economy.

Cursor is the AI code editor whose background agents plan, edit and test changes across a repository while the developer keeps working.

Cursor reached $2B in ARR by February 2026 after doubling in about three months, with over a million paying customers, roughly 50,000 enterprise teams and about 70% of the Fortune 1000 using it. It became the largest startup acquisition ever when SpaceX agreed in June 2026 to buy Anysphere, its parent, for $60B days after SpaceX's Nasdaq debut, with closing scheduled for the third quarter. Cursor Ultra subscribers now get early access to SpaceXAI's Grok Bot, and the editor keeps running Claude, GPT and its own coding models.

Devin is an autonomous software engineer that takes tickets and ships pull requests from a sandbox; Windsurf is its agentic IDE.

The largest independent coding-agent company: run-rate went from $37M to almost $900M in sixteen months, with a $48B valuation after a $2B+ Series E in September. Cognition bought Windsurf in 2025 after Google hired its core team, so it owns both a fully autonomous agent and an editor with over a million users. Customers skew to banks and industrials: Citi, Goldman Sachs, GE Aerospace, Mercedes-Benz, NASA.

Enterprise customer-experience agents that handle whole interactions (returns, claims, refinancing) across voice, chat and email.

Sierra is the scale leader in enterprise customer-service agents: $200M ARR by May 2026, doubling in six months, with 40% or more of the Fortune 50 as customers. Its agents act inside customers' back-office systems rather than answering questions, and deployments go live in as little as five weeks. It raised $950M at $15.8B months after its previous round and holds over $1B in cash.

Legal AI with agentic workflows for research, document review, drafting and diligence, used by law firms and in-house teams.

Harvey defined the legal-agent category and roughly doubled ARR during 2026 to over $400M, with its valuation going from $11B to $15.5B in six months. It chains several models and tools into pre-built legal workflows and is used by most of the Am Law 100. Over 142,000 lawyers across 60+ countries work in it.

An agent that builds, edits and deploys full-stack apps from plain-language prompts.

Europe's largest AI agent company by valuation and one of the fastest software companies ever to scale revenue: $4M ARR four weeks after launch, a $600M run rate under two years later. Sixty million projects have been created on it and employees at nearly two thirds of the Fortune 500 use it. It is also the app builder most used by AI Lounge members.

A collaborative legal workspace whose agents review, draft and research across a firm's documents and the public record.

Harvey's fastest-growing rival, built in Stockholm: ARR passed $200M in September 2026, with 2,100 firms and legal teams in more than 80 countries and 130,000 lawyers using it monthly. It raised a $600M Series D at $5.6B in 2026, led by Accel, bringing the total to more than $850M. Its edge is a tabular review product that lets lawyers run one agent across hundreds of documents at once.

A platform for building conversational voice agents on ElevenLabs' speech models, deployed by Revolut, Klarna and others for phone support.

ElevenLabs turned the best-known voice synthesis company into an agent platform: customers have deployed more than 2 million conversational agents handling over 33 million conversations, and 41% of the Fortune 500 use the platform. ARR was $330M at the start of 2026 and the company raised a $500M Series D led by Sequoia at $11B in February 2026, with a tender reported at $22B later in the year. Its advantage is owning the speech stack end to end, including sub-150ms transcription in 90 languages.

Work AI that searches across a company's apps and runs agents grounded in company data and permissions.

Glean's agents run on a permission-aware index of 250+ enterprise connectors, which gives them context generic agent builders lack. ARR passed $300M in May 2026, fifteen months after $100M, and its Fortune 500 customer count nearly doubled in a year. Most customers use it across five or more departments.

Replit Agent builds, deploys and hosts full applications from a description, with databases, auth and payments included.

Replit turned a browser IDE with 50 million registered users into an agent that non-engineers use to ship software: ARR reached about $265M at the end of 2025 and the company is targeting $1B for 2026. Its valuation tripled in six months to $9B on a $400M Series D in March 2026, and employees at 85% of the Fortune 500 use it. Unlike pure code generators it owns the whole stack, so an agent-built app runs on Replit's own hosting.

An agent platform for enterprise customer service that handles phone and chat conversations end to end.

Parloa tripled its valuation to $3B in eight months with a $350M Series D and crossed $50M ARR, making it Europe's largest customer-service agent company. It specialises in voice at contact-center scale for enterprises in Germany and the US, and runs an agent-management layer for testing, simulation and quality control before agents go live.

AI concierge agents that resolve support across chat, email and voice and take actions in company systems.

The second-largest independent customer-service agent company after Sierra; its valuation tripled to $4.5B in seven months. Agents are configured in natural-language 'Agent Operating Procedures' that business teams edit without engineers. Customers are high-growth digital businesses: Notion, Duolingo, Rippling, Chime, Affirm, Block.

Virtual nurses and care coordinators that call patients for pre-op prep, discharge follow-up and chronic-care check-ins.

Hippocratic sells non-diagnostic clinical agents by the hour, priced below a nurse's wage, to health systems including Universal Health Services, WellSpan and Cincinnati Children's. Its safety approach is a constellation of specialist models that check each other, with every agent reviewed by licensed nurses and physicians before release. It raised a $126M Series C led by Avenir Growth in November 2025 at a $3.5B valuation, for $404M in total.

Agents for personal-injury law firms that turn case files into demand letters, medical chronologies and negotiation work product.

EvenUp owns one legal vertical end to end: more than 2,000 of the roughly 48,000 active personal-injury firms in the US use it, and its demand letters are built from a proprietary dataset of past settlements that lets the agent argue for a number. It raised $150M in an October 2025 Series E led by Bessemer at a valuation above $2B, for $385M in total. Its agents now run intake, litigation drafting and case management, not just the demand.

A search engine and API built for agents: prospect research, technical documentation and code.

Exa built its own crawler, models and databases instead of repackaging another search engine, and sells search designed to be consumed by LLMs rather than people. Over 500,000 developers and 5,000 companies use it, including Cursor, Cognition and HubSpot. Its valuation more than tripled in seven months, from $700M to $2.2B.

An enterprise platform for building and supervising agents on Writer's own Palmyra models, with the governance large companies require.

Writer sells to regulated enterprises that want agents without sending data to a frontier lab: it trains its own Palmyra model family, ships an agent builder with audit trails, and counts over 300 enterprise customers including Uber, Mars and Qualcomm. It raised $200M at a $1.9B valuation in late 2024 and took a strategic investment from Salesforce Ventures in October 2025. Its pitch is cost and control rather than raw model quality.

Contact-center agents that handle calls and chats autonomously and coach human agents in real time on the rest.

Cresta started as a real-time coaching copilot for human agents and now sells autonomous virtual agents alongside it, so a contact center can move work between the two. Customers include United Airlines, Cox Communications and Marriott, and it has raised more than $270M, most recently a $125M Series D co-led by World Innovation Lab and the Qatar Investment Authority in November 2024. Its differentiator is the behavioral data from millions of coached conversations that trains the autonomous agents.

The open-source framework and LangGraph runtime that many production agents are built on, plus LangSmith for tracing and evaluating them.

LangChain is the most widely used agent framework, and LangGraph is its runtime for stateful, long-running agents with checkpoints and human-in-the-loop steps; Klarna, Replit and Uber have built on it. The business is LangSmith, the observability and evals product teams pay for once an agent is in production. It raised a $125M Series B led by IVP in October 2025 at a $1.25B valuation, for $260M in total.

A visual workflow platform where an AI Agent node, 1,000+ integrations and human-approval gates let teams build and run their own agents, self-hosted or in the cloud.

n8n is how a large share of working agents actually get wired up: 1.7 million monthly active builders on the free self-hosted edition, a fair-code license that lets companies run it on their own servers, and an AI Agent node that pairs a model with tools, memory and approval steps. It raised a $180M Series C led by Accel at $2.5B in October 2025, and SAP invested more than EUR 60M in May 2026 at a $5.2B valuation to embed it in Joule Studio. It is the open alternative to Zapier for agent workflows.

Autonomous red teamers that probe applications, find vulnerabilities and build working exploits.

XBOW proves exploitability instead of flagging possibilities: 14,000+ working exploits found in customer applications, and it reached the top of the HackerOne leaderboard. The team came from the original GitHub Copilot group (de Moor created Copilot). Over 200 customers include major banks, Fortune 500 companies and cloud providers.

Claygent is a research agent inside Clay's go-to-market platform that enriches accounts, finds signals and drafts outreach across 150 data sources.

Clay became the system of record for AI-driven outbound: its spreadsheet-like workflows and Claygent agents are used by the sales teams at OpenAI, Anthropic, Canva and Vanta, and ARR passed $100M at the end of 2025. It reached a $5B valuation in a January 2026 employee tender led by DST after a $100M Series C at $3.1B led by CapitalG in August 2025, on roughly $200M of primary capital. The company is a profitable, capital-light outlier among the GTM agents.

Enterprise voice agents that answer the phone, resolve the call and hand off to a person only when needed, in 45 languages.

PolyAI has more than 2,000 live voice deployments across 25 countries and over 100 enterprise customers, with a reputation for voice agents that survive accents, interruptions and bad phone lines. It raised an $86M Series D co-led by Georgian, Hedosophia and Khosla Ventures in December 2025, taking total funding past $200M, and its Agent Studio lets customers build their own agents on its stack. Founded by Cambridge machine-learning researchers, it is the leading European company in the category.

Bolt agents act as admissions consultants for colleges: answering aid questions, nudging applicants, reviewing transcripts and flagging fraud.

Goal-driven 'Agent Jobs' start outreach, track milestones and pause for human approval before steps like completing an application or collecting documents, which replaces canned reminder emails with tailored follow-up. Over 400 colleges and universities run the platform, and Bolt can sit on top of an existing CRM, SIS or LMS. PSG put $175M into the company in late 2024.

An agent for investment bankers and investors that builds decks, audits models and runs research inside Excel, PowerPoint and Word.

Rogo is the finance-specific agent that banks have actually deployed: Moelis, Nomura, GTCR and several large European banks run it on their internal data. It raised a $75M Series C led by Sequoia in January 2026 at a $750M valuation, with $165M raised in total, and Bloomberg has reported a subsequent valuation around $2B. Founded by former Lazard bankers, it sells on the hours it removes from pitch-book and model work.

Hermes is an open-source, self-improving agent framework you run on your own servers, desktop or messaging apps.

The open-source counterweight to closed agent products: 22 million downloads since February, 214,000 GitHub stars, and Fortune 500 companies rolling it out to employees because the data never leaves their servers. It learns skills from how people use it without developer work and runs on a VPS, a desktop or inside Discord and Telegram. A provocative brand (its CMO goes by SHL0MS) has not slowed enterprise adoption; it raised $90M at $1.5B this week.

Marketing agents that plan, write, localize and optimize campaigns on a company's brand voice and style rules.

Jasper was the first breakout generative-AI company, reaching a $1.5B valuation on $131M raised in 2022, and it has rebuilt itself around agents for marketing teams: brand-trained models, an agent builder and prebuilt agents for SEO, performance ads and product marketing. It has about 70,000 customers and sells to enterprise marketing organizations rather than individual writers. Based in Austin, it is the largest marketing-specific agent company by customer count.

An AI coworker that runs order-to-cash end to end: credit, collections, cash application, disputes and deductions.

Stuut targets the whole order-to-cash cycle at large enterprises, not reminder emails: $3B+ has moved through it, it has collected $21M+ for ZoomInfo alone, and it says 81.7% of outbound collections run with no human involvement. It builds a persistent memory of each customer's payment behaviour and portals, logs every action, and requires approval before changing behaviour. Customers include Honeywell, Verifone and NCR Voyix; it raised a $52.5M Series B from Insight this week.

An AI employee that lives in Slack and Microsoft Teams and works across a company's tools to finish tasks and recurring workflows.

Many startups claim an 'AI employee'; Viktor cites revenue: a $50M annualized run rate in under seven months, from $15M in May to $20M in June, with no salespeople. It is built for whole teams rather than individuals, keeps persistent organisational memory, and scans public channels to propose workflows it can take over. Accel led a $75M Series A with Slack's founders as angels.

Townies are character-based AI coworkers you text, and that join group chats, for inbox-driven work like monitoring supplier prices or chasing clients.

Each Townie learns how you work rather than making you learn a tool, and coordinates with your teammates' Townies; paying businesses grew ninefold between July and October at $50–$200 per user per month. Town's data policy is the differentiator: no training on customer data, most data deleted after 15 days, and access through connected software instead of stored copies. Greze was Plaid's CTO; a16z led the $55M Series A.

Agents that run loan servicing and consumer-finance operations: collections calls, payments, disputes, compliance monitoring and customer service.

Salient takes over work that used to go to offshore operations centers, for Westlake Financial, AutoNation Finance, Exeter, Ally and three of the ten largest US banks, and reports $40M+ annualized revenue, up from $14M in mid-2025. Its engineers embed on site with customers, it says every pilot has converted to a paid deal, and it is building toward an autonomous system of record for loans with credit reporting and charge-off modules.

Cloud browsers that let other companies' agents load sites, click, enter data and transact, plus a one-call Agents API.

Browserbase sells the infrastructure layer rather than an assistant: over 10,000 companies build on it (Ramp, Shopify, Lovable among them), it served about 37 million browser sessions in March, and it has automated more than 2,000 years' worth of browsing. The open-source Stagehand SDK sees 800,000 weekly downloads, and the 2026 Agents product hosts the whole agent loop and returns structured results.

Ava is an AI BDR that finds prospects, enriches them, writes and sends outbound sequences and books the meetings.

Artisan is the best-known of the AI sales-rep companies, partly for its 'Stop hiring humans' billboards and partly because Ava bundles the data, signals, sequencing and inbox management that usually take four tools. It raised a $25M Series A led by Glade Brook in April 2025 for $46M in total, with HubSpot Ventures and Y Combinator on the cap table. The product sells to small and mid-size sales teams that would otherwise hire a first SDR.

An AI assistant that runs shrimp farms in shipping containers, turning farm data into the day's tasks for on-site workers.

The software models shrimp biology and biofloc water chemistry so people with no aquaculture background can run a farm: Atarraya trained former construction workers as shrimp farmers in three weeks. The flat-packed Shrimpbox tanks deploy quickly, and the company is moving to an asset-light model with the Middle East (a UAE pilot with Silal) as a growth market. It has raised $22M.

An agentic ad agency: agents plan campaigns, generate creative, place and optimize ads across TikTok, Instagram, Google, Reddit and Pinterest.

AdsGency runs the whole media-buying loop with agents rather than selling a tool to a human buyer, and it connects to data and CRM systems such as Snowflake and Salesforce for attribution. Customers report results such as 13x return on ad spend at Halliday and 3x at TAL Education. Founded by an engineer who built ad systems at AWS and DiDi, it raised a $12M seed led by XYZ Venture Capital in October 2025.

Pion is a platform for running an entire business with persistent agents that have email, phone, banking, cards and a browser.

Andon tests whether agents can run real businesses, not whether they can chat: its agents run a boutique on Union Street in San Francisco (writing job posts, interviewing applicants, managing human staff), a cafe in Stockholm, vending machines and four radio stations, with a supervisor agent, Andonos, watching the operator. The store is not profitable yet, and Pion's waitlist drew thousands of companies from 40+ countries. YC-backed, with only a small round raised.

Agents for government tax agencies that assemble documents, reconcile records and link evidence to law, with officials making the decisions.

Govra builds for the enforcement side of tax: a pilot with California's Department of Tax and Fee Administration, with Indiana, Wisconsin and New Hampshire following, where an official sees room for 20–30% more audits because auditors spend a third of their time assembling material. It runs inside the agency's own environment so every step is auditable, never picks targets or makes final judgments, and former IRS commissioner Danny Werfel advises. Seed round from General Catalyst, amount undisclosed.

Phone, text and web-chat agents for funeral homes that handle overnight calls, scheduling and document workflows.

Built by a sixth-generation funeral director inside his own 13-home business, with one non-negotiable rule: if a caller asks for a real person, the agent transfers immediately. It targets direct-cremation and online providers as well as traditional homes, and it is one of the few companies on this list with no venture money and no revenue yet.

A Slack and Teams coworker for small marketing agencies: client reports, spend alerts, call recaps and invoicing, with approval before anything goes out.

Named after the founder's mother, Patricia behaves like a back-office teammate rather than a chatbot: it keeps a memory of each client, watches invited channels for work that has slipped, and turns Google Ads, Meta, GA4 and Search Console into finished weekly reports. Every email, post, change or spend waits for an in-channel approval and lands in an audit trail. It is priced for the whole agency, $45 a month for every seat, and sits inside BetterGroup alongside BetterPic.

A Slack-native agent that analyzes Meta Ads accounts, generates creative and executes optimizations for DTC brands, agencies and freelancers.

Rocco comes out of Everything Clicks, a performance-marketing agency with thirteen years of playbooks and $450M+ of Meta spend managed, so its recommendations read like a senior buyer's. A 9am briefing lands in Slack with the day's to-dos; RoccoGo pauses ads, reallocates budget and adjusts ad sets from Slack commands, and RoccoCreate drafts new creative modeled on the account's winners. Plans start at $59 a month for three ad accounts.

An AI teammate in Slack, Teams, iMessage/SMS and a mobile app that answers with sources and runs tasks and recurring work across 3,200+ tools.

Henry meets people where they already talk, including iMessage and SMS, instead of in another app, and anything that sends, books or spends waits for approval. It is model-agnostic (Anthropic, OpenAI, Google and xAI models switchable per workspace) with persistent memory, scheduled tasks, voice and teachable skills, plus SAML SSO, per-workspace encryption keys, bring-your-own model keys and self-hosting for enterprises. Pricing is flat credits, $2 per 1,000.
