01 Advisors

01 Advisors, co-founded by former Twitter executives Dick Costolo and Adam Bain, is a San Francisco-based venture firm that distinguishes itself through its operator-led investment approach. Established with the core premise of leveraging deep operational experience, the firm actively partners with entrepreneurs to navigate the complexities of scaling high-growth technology companies. Their extensive backgrounds in building and managing a hyper-growth organization like Twitter provide them with unique insights into product development, market expansion, and organizational scaling.

The firm primarily focuses on growth-stage companies, typically participating in Series B and C funding rounds. Their investment philosophy centers on identifying businesses with strong product-market fit that are poised for significant expansion, where 01 Advisors' hands-on operational guidance can add substantial value. They target sectors such as enterprise software, fintech, and consumer technology, seeking out companies that can benefit from their expertise in areas like infrastructure, talent acquisition, and go-to-market strategies.

01 Advisors typically deploys initial checks ranging from $10 million to $50 million, reflecting their focus on later-stage, capital-intensive growth opportunities. While this is their common range, they have demonstrated the capacity to write larger checks, reportedly up to $100 million, for strategic lead investments in particularly high-potential companies. The firm successfully raised its debut fund of $200 million in 2019, followed by a second fund of $300 million in 2022, underscoring their growing capital base and commitment to their investment strategy. These fund sizes enable them to make meaningful contributions to their portfolio companies' funding rounds and support their long-term growth trajectories.

Beyond providing capital, 01 Advisors emphasizes its role as a strategic partner, offering practical advice and mentorship. Their team, composed of seasoned operators, provides guidance on critical aspects such as organizational design, product strategy, and market entry. This operational expertise is a core differentiator, aiming to help founders avoid common pitfalls and accelerate their path to success. Their portfolio includes several high-profile companies, demonstrating their ability to identify and support future industry leaders.
