Venture Capital

Slow Ventures

Slow Ventures is a generalist early-stage venture capital firm founded in 2011 and headquartered in San Francisco, with additional offices in Boston and New York. The firm leads pre-seed and seed rounds, writing typical checks of roughly $500K to $3M (averaging around $1.75M), and explicitly rejects thematic investing in favor of backing experienced founders with deep, hard-won domain expertise and genuine conviction. Slow's thesis funds rapid, high-stakes experimentation: capital that tests a novel risk or hypothesis whose validation dramatically increases a company's value and that cannot easily be funded another way. As a generalist, Slow invests across consumer and social, fintech, SaaS and enterprise/developer tools, healthcare, crypto/web3, the creator economy, and real-world operations (SMB acceleration, buyouts/rollups, franchising). The firm runs a dedicated Creator Fund backing creator-led businesses, and has deployed roughly $800M+ across multiple fund vintages since inception. Notable investments include Pinterest, Slack, Robinhood, Nextdoor, Postmates, Opendoor, Wealthfront, Casper, PillPack, Airtable, Gusto, and Solana.
