Sam Lessin is an 🏷️#investor, 🏷️#founder, and former product 🏷️#operator, and a General Partner at 📝Slow Ventures, the early-stage venture firm he co-founded in 2011. He writes the "Modest Proposals" column at The Information, where he lists his title as "intern," and co-hosts More or Less, a podcast on technology and capital produced by The Information, Offline Ventures, and Slow Ventures. A 2005 📝Harvard University graduate, he founded the file-sharing startup Drop.io in 2007, which 📝Facebook acquired in 2010.

At Facebook from 2010 to 2014, Lessin ran the Identity product group, responsible for profiles and privacy, and later served as VP of Product Management over the "People, Places, Things" group. He co-founded the AI-assisted work company Fin in 2015. Slow Ventures' early bets include 📝Venmo, 📝Airtable, 📝Gusto, 📝Clay, and 📝Solana, and the firm runs the Slow Creator Fund, which backs creators turning audience trust into businesses. He was named among the backers of TrustedRouter, an open-source AI model router, in 2026. Publicly, he has criticized the "factory model" of venture capital, argued that AI alignment will 📝matter more than technical capability, and contended that software buying is splitting between expensive enterprise sales and purchases delegated to LLMs. In 2024 he petitioned for a seat on Harvard's Board of Overseers.
