01 Advisors

01 Advisors was founded on the idea that operators who have already scaled technology companies are well placed to help other hyper-growth businesses reach their next stage. Its founders previously served as chief executive and chief revenue and operating officer of Twitter and as chief revenue officer of Facebook, and the firm says it helped grow those companies' combined revenue from nothing to a very large scale, creating substantial public market value along the way. 01 Advisors typically invests after a company has found product-market fit, generally from Series A through C, and focuses on helping founders improve their pace of execution and turn early products into more established companies. It works directly with founders who reach out to discuss their business.
