VC Built for Vertical software.
Your Partner from Inception.
WHat we Do

We back domain experts building category-defining vertical software companies for large, underserved industries.

Over 50% of software exits today are vertical, yet little infrastructure exists to support vertical software founders from Day Zero.

Vertex, our collective of 60+ leading CEOs and industry executives, is a network & center of excellence for Vertical SaaS operators, helping us partner with and support top founders from inception.


We invest exclusively in what we know: software founders with unique domain expertise (usually from industry roles or past startups) transforming the backbone industries of the economy. We write initial checks of $500k to $1.5m, typically leading or co-leading pre-seed or formation-stage rounds. On average, Euclid partners with only 6 new companies per year, as we dedicate most of our time to our existing founders. Based in San Francisco, CA, we bring Silicon Valley networks and resources to standout founders across the US and Canada (with a core presence in and initial focus on those markets).


Our founders are our priority. We build life-long professional partnerships centered around achieving outlier outcomes. We help founders build industry-dominant platforms, leveraging the support of leading vertical CEOs who have been there before. Euclid aims to be the first of many excellent partners on our founders' cap tables and their first call, in good times and bad. While we're experts in the journey from Day Zero to Series A, we do reserve capital to support our portfolio through future rounds. We are long-term thinkers, investors, and advocates.
