Who We Are

Flatirons Development was founded in 2018 with a mission to build beautiful consumer facing software that improves business metrics for early-stage companies.

Flatirons Fund was launched in 2020 to encourage innovation during a troubled economic climate and the years beyond. Our goal is to advance and support a new wave of founders, particularly women and people of color who have traditionally been underrepresented in venture capital.
