I'm building Paragraph, the media engine for early-stage startups. We help founders turn launches, product updates, and what they're learning into media they own. We've raised $7 million from investors including USV and Coinbase Ventures, and in 2024 we acquired Mirror.

Before that, I led anti-abuse and privacy engineering teams at Google and helped build Coinbase's payments infrastructure. I also angel invest in early-stage startups like Farcaster, Daimo, and Layer3, and in a few venture funds that do the same.

On the side I build small tools like Appears, heade.rs, Draftside, and Council. In my free time I enjoy photography , wine, cooking & cycling.
