AIX Ventures
About AIX Ventures
AIX Ventures is an AI fund and seed stage venture capital firm partnering top AI startups and AI practitioners. The firm specializes in investing in early-stage companies, particularly in the Pre/Seed stages, to foster innovative AI-driven solutions. Per Crunchbase, AIX Ventures has made 52 investments, 19 as lead investor across 48 portfolio companies, with 5 exits.
AIX Ventures was founded in 2021 and is headquartered in San Francisco. Richard Socher, a former chief scientist at Salesforce and founder of You.com, is a founding partner, along with Pieter Abbeel, Anthony Goldbloom and Christopher Manning. Shaun Johnson, a co-founder, leads the full-time team and previously held engineering, product and design leadership at Lilt. Fund I, a $50 million vehicle, closed in October 2021 and included Socher's angel portfolio. Fund II, at $202 million, was announced in February 2024 to back early-stage AI companies. A firm listing names Krish Ramadurai, Jason McBride and Lucy Chong as partners alongside the general partners.
The firm says it invests only in AI-native companies, where AI is the core product and the main competitive advantage rather than a feature. It names three baskets: AI infrastructure such as vector databases and model serving, vertical applications with a clear performance edge, and frontier research with a route to commercialization. The partners are active AI practitioners, and the firm says this lets its team understand founders' technical problems firsthand. Fund II was described as focused on AI applications and infrastructure that change how people and teams work. Early backings include Hugging Face, Weights & Biases, You.com and Perplexity. Chroma is named among current holdings in the Fund II announcement. Crunchbase lists AIX Ventures as lead investor in a Series A for Ataraxis, with Krish Ramadurai as the named partner.
Fund I was focused on Pre-Seed and Seed startups. Fund II was described as enabling the firm to lead more rounds, and one research profile says the firm's ticket size expanded to lead Series A rounds while it kept seed-stage deployment. Third-party listings disagree on check size: one shows $750K to $3M across Pre-Seed, Seed and Series A, another shows $100K to $1M, and a third shows $1M to $5M. I found no check size on the firm's own site, so founders should confirm terms directly with the firm.
