What we do

We back domain-expert founders building category-defining vertical software businesses. Over 50% of software exits today are vertical and AI is accelerating a generational opportunity. Euclid is the first early-stage fund dedicated to the category.

Euclid leads and co-leads inception-stage and pre-seed rounds. We are highly concentrated, backing only a select few founders per year and dedicating 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.

Our community

We also run the Vertical Software Collective, an invite-only network & center of excellence for leading vertical operators. VSC comprises 100+ members today, from breakout startup CEOs to post-IPO founders. Our simple aim is to connect and bring value to the best in vertical software.

How we partner

Founders are our priority. We build life-long professional partnerships centered around achieving outlier outcomes. Euclid helps founders build industry-dominant platforms, leveraging the support of leading vertical CEOs who have been there before, and partnering well before we invest. In addition to our portfolio, we aim to serve the broader vertical software ecosystem, through VSC and through the insights we share here.
