25Fifteen is a startup studio founded by successful tech entrepreneurs and industry veterans. We use our execution experience, capital, and relationships to build valuable companies that improve people's lives.

We are builders. We get deeply involved in every company we work with. In almost all cases we get involved at Day 0. Most companies start as internal projects.

From time to time we co-found companies with external founders who share our philosophy for how to build companies of value.

Some of the Companies We've Been Involved With

25Fifteen is led by Luke Carruthers and Kim Heras, supported by a team of experienced startup founders, developers, designers and investors.
