01 Advisors (01A) is an early-growth venture capital and advisory firm founded in 2018 by former Twitter CEO Dick Costolo and former Twitter COO Adam Bain, with former Facebook Chief Revenue Officer David Fischer as a third general partner. Headquartered in San Francisco with a New York office, the firm positions itself as "venture coaches" that deliberately avoid taking board seats, focusing on Series B companies with product-market fit that need help building professional sales organizations and revenue operations. It manages roughly $920M across multiple funds. Added to the API Evangelist network as a venture-capital portfolio lead surfaced via foundry-group; the firm runs a corporate marketing website (Squarespace) and publishes no public API, developer portal, or machine-readable surface.
