About
What Distributional was, who built it, and where it went: the AI testing and analytics era, the funding, and the hard pivot to Talaria Scientific.
Distributional was co-founded in 2023 by Scott Clark to solve AI testing for the enterprise: rigorous, repeatable ways to know whether the AI systems teams were shipping actually behaved the way they believed. In late 2025 that sharpened into behavioral analytics for AI agents in production.
The company raised $30M and served Fortune 500 enterprises: an $11M seed led by a16z in 2023, then a $19M Series A led by Two Sigma Ventures in 2024.
In July 2026 Distributional made a hard pivot to Talaria Scientific: the same Delaware corporation and the same investors, pointed at a problem where the team has an unfair advantage (a multi-agent harness for computational science). The announcement tells the honest story of what worked, what didn't, and why.
