WHat we do

Euclid invests in domain-expert founders building software trasform the foundational industries of the economy.

These under-digitized sectors represent a massive, underserved opportunity: despite composing about 50% of US GDP, they receive less than 12% of all venture funding.

Vertex, our network powered by 100+ leading CEOs and industry executives, helps us partner with and support top industrial innovators from Day Zero--before they land on Silicon Valley radars.


We invest exclusively in what we know: Industrial Innovators. These are 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. Euclid only partners with 6-8 new companies per year, as we dedicate most of our time to ongoing support for our existing founders. Based in San Francisco, CA, we bring Silicon Valley networks and resources to standout founders with a core presence in -- and initially focused on markets in -- the US and Canada.


Our founders are our priority. We build life-long professional partnerships centered around achieving outlier outcomes. We work with founders to accelerate past key challenges, leveraging the support of leading CEOs who have overcome them firsthand. While we specialize in the journey from Day Zero to Series A,  we do reserve capital to continue to support our portfolio and participate in future rounds. We are long-term thinkers, investors, advisors, and advocates: while Euclid aims to be the first of many excellent partners on our founders' cap tables, we aim to be a CEO's first call well beyond early stages -- in good times and bad.
