I co-founded Onsite Pro (S21, formerly known as Greenwork), which is at the intersection of climate and construction. In the recent past I've worked on marketplaces with SMBs and local workers (DoorDash, Rickshaw), and experimented with how the marketplace evolves when software/robotics are added in. I also co-founded Rickshaw (W14) and Jamglue (S06). Fun fact: since 2006, I've worked at five YC-backed companies, and zero non-YC-backed companies.
