We partner with relentless founders who defy convention to change the future. Our four founder paradigms—purity of motivation, earned secret, obsessed problem solving, and non-consensus thinking—guide our investment decisions. We believe the best founders are intrinsically motivated to solve real problems, have deep domain expertise, relentlessly iterate to find better solutions, and have the courage to diverge from established paths.

We avoid founders chasing trends for quick exits, lacking domain expertise, or unable to pivot when needed. We avoid me-too products without differentiation.
