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.
