Hi there, I’m Boris. I’m currently a visiting partner at Y Combinator helping new founders build amazing companies.

Previously I was the co-founder and CEO of Census, a data activation platform that syncs data from data warehouses into business tools, which was acquired by Fivetran. Before that, I founded Meldium, a password manager for teams, which was acquired by LogMeIn.

Along the way I’ve invested in startups including Rippling, Fal, Hex, Orb, Felt, Graphite, Statsig, Modal Labs, Ashby, Nitra, and Zed.

I grew up in Canada & France before eventually moving to the US for graduate school. These days, I split my time between San Francisco and New York. I moonlight as an amateur tour guide if you’re visiting.

Someday, I hope to recreate the magic of HyperCard.
