Nebuly raises $21M Series A led by Planven to measure enterprise AI agent ROI
Turin-based Nebuly S.r.l. raised a Series A of €18.95 million, or about $21 million, led by Planven, according to SiliconANGLE, which reported the round on November 12, 2026. Exor Ventures, Tenacity Capital, TGVG Capital, Fastweb, Vodafone and the Digital Transition Fund of CDP Venture Capital also invested. TechFlow, citing EU-Startups, says Fastweb and Vodafone took part through Founders Factory and that existing and angel investors joined as well.
Nebuly was founded in 2022 by Francesco Signorato, Julien Roux and Diego Fiori. Its platform measures how AI agents change business results, covering tools employees use and assistants that talk to customers. For internal agents it estimates efficiency gains such as labor savings and freed capacity. For customer-facing agents it tracks revenue effects, churn risk and upsell. The Next Web notes that finance teams can examine and change the assumptions behind the output. The product connects to agents built on Claude, ChatGPT and Microsoft Copilot and can run on-premises or in a private cloud.
Named customers include Carl Zeiss, Iveco and Oura. Nebuly plans to use the money to expand sales and go-to-market teams in the US and Europe and to keep developing the platform. Tech Funding News reports the headcount will rise from 40 to 60.
Why it matters
For teams building AI products, buyers are moving from usage counts toward measured returns. Francesco Signorato argues that counting users and prompts has encouraged companies to treat usage as the goal. Founders should expect procurement teams to ask about attributable revenue and cost, and should instrument agents to report outcomes from the first release rather than retrofit tracking later.
For investors, the round points to a market for independent measurement layered over models from OpenAI, Anthropic, Microsoft and Google. SiliconANGLE reports Signorato's view that many companies run a patchwork of such tools alongside in-house builds, which makes attribution hard. Vendors should expect finance teams to demand transparent calculations, so tools that expose their assumptions may have an edge in procurement over opaque scores.
