first-check partner to founders rewiring their industries for the digital economy.

We help domain experts build
industry-transforming businesses.

WHat we do

We believe the most important B2B companies of the next decade will be Multisided Platforms, as every industry is rewired for the digital economy. These purpose-built software platforms are redefining entire B2B value chains, but changing an industry’s status quo requires a different kind of founder.

Built by seasoned early-stage investors with the support of 40 leading CEOs, we help domain experts build industry-transforming businesses.

our
focus

We invest exclusively in what we know -- founders with unique domain expertise reshaping an industry's value chain. We write initial checks of $750k to $2m at the Pre-Seed and Seed stage and reserve capital to participate in future rounds. We typically lead or co-lead. Euclid only partners with 6-8 new companies per year, as we dedicate most of our time to ongoing support for our existing founders. We are based in San Francisco, CA and partner with teams across the US and Canada.

Long-term
Partners

Our founders are our priority. We build life-long professional partnerships centered around achieving outlier outcomes. Euclid's post-investment platform accelerates companies in 3 key ways: Multi-sided Product-Market Fit, Early Growth & Monetization, and 1x1 Founder Mentorship. We aim to be your first call -- in good times and in bad.

THIS IS
HOW WE HELP
Finding
Product-Market Fit

Finding multisided product-market fit is hard. We've helped dozens of companies reach this critical early milestone.


EArly  growth

Platforms grow differently. We help you optimize liquidity, monetization, and G2M to inflect your business.


1x1 Mentorship
