Euclid is the first-check VC for vertical software. More on us here.

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.

We also run Vertex, a network & center of excellence for vertical software operators. The collective comprises 100+ members nationwide today, from breakout startup CEOs to post-IPO founders. Vertex’s simple aim is to connect and bring value to the best in vSaaS.

Our focus

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).

How we partner

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.
