Their mission is to support hyper-growth startups, primarily at Series A through C stages, by providing operational expertise and strategic guidance.

Founded in 2018 and headquartered in San Francisco, 01 Advisors was established by former top executives from Twitter and Facebook, including Adam Bain (former Twitter COO) and Dick Costolo (former Twitter CEO).

01A rides the wave of increasing demand for operational expertise in venture capital, especially for startups moving beyond early product validation to scaling.

By combining capital with operator insight, 01A influences the ecosystem by helping startups grow efficiently and sustainably, potentially increasing the success rate of venture-backed companies[1][3].
Looking ahead, 01 Advisors is poised to deepen its impact by continuing to back startups at pivotal scaling stages, especially in AI and fintech sectors where rapid innovation and market shifts demand strong operational leadership. Trends like AI integration, data-driven decision-making, and fintech disruption will shape their portfolio’s growth trajectory. Their influence may expand as more founders seek operator-led venture partners who can provide both capital and hands-on scaling expertise, reinforcing 01A’s role as a key enabler of hyper-growth companies[1][3].
