Not Just Founder Friendly.
We Are Founders.


Evolving the Venture Model

Our unique approach puts experienced CEOs at the center of the investment process. Our team combines seasoned venture investors and Dual Threat CEOs – founders who are running companies and also investors at Flex.

We've Been There Before And Are Still In the Game

We are the founding CEOs of companies like LiveRamp (NYSE: RAMP), Brightroll, SafeGraph and Pipedream. We are investors in 200+ companies including Chime, Coinbase, Niantic, StockX, GetYourGuide, Marqeta, and Datavant. We have led companies from founding to $300m+ in annual revenue and hundreds of employees. 

Deep Alignment & Hyper-Relevant Experience

We are in the same shoes as the entrepreneurs we support. We get the founder’s journey because we are still on it ourselves. We believe in relationships built on trust and growth, instead of control. We want to be the first call without fear of repercussions.

Seed to Series B

We believe in empowering our fellow founders at the early stages of development. Whether we’re leading the next round or playing a supporting role on the cap table, we want to be on the team helping founders take breakthrough ideas and turn them into world-changing companies.
