OpenAI, the company behind ChatGPT, has announced plans to acquire Statsig, a product testing startup, in a $1.1 billion all-stock deal. The acquisition marks one of the largest in OpenAI’s history and underscores its ambition to enhance product development and scale its AI-driven applications.
About Statsig
Founded in 2021, Statsig provides tools that help software developers test, measure, and flag new features before rollout. According to its website, the company’s services are used by employees at OpenAI, Eventbrite, SoundCloud, and several other tech firms.
Earlier this year, Statsig raised $100 million in funding, valuing the company at $1.1 billion, the same valuation reflected in this acquisition.
