Rockstar🎓
Top SchoolRob Olsthoorn is an entrepreneurial software engineer with 11 years of experience building product-led platforms and taking ideas from 0 to market. As founder of Bobby Boy Holdings and former Co-Founder/CTO of a YC startup, he blends hands-on engineering with product strategy, most recently helping Whatnot scale core marketplace and NFT offerings that drove meaningful GMV. He’s equally comfortable across the stack—Python/React, native iOS, Postgres/Dynamo, Elasticsearch—and has shipped systems supporting ~1M weekly active users. Rob has deep crypto and partnerships experience from roles at dOrg and projects with Starkware/Opolis, and he frames technical decisions through user research and JTBD thinking. Relentlessly curious and self-experimental by nature, he combines a hacker’s mentality with repeatable go-to-market instincts.
