I like building

hard things.

Especially when they're physical. Sold a computer vision startup. Currently building a microplastics testing kit, writing code at Wonderly, and buying software companies through xo.capital.

Finding MRR — we're all just trying to find some monthly recurring revenue. Weekly.
