OpenAI Acquires Statsig, Brings in Vijaye Raji as CTO

OpenAI recently announced the acquisition of Statsig in an all-stock deal worth approximately USD 1.1 billion. The deal, valued using OpenAI’s $300 billion valuation, is one of the company’s largest to date. Statsig specializes in A/B testing, feature flagging, and real-time decisioning. Its tools have already supported OpenAI’s own rapid experimentation efforts. The acquisition is set to enhance OpenAI’s ability to iterate quickly and improve product reliability as your experiences scale.

Post-deal, Statsig will continue operating independently from its Seattle office under regulatory approval; its team will transition to OpenAI but maintain continuity for current customers.

The Proven Leadership of Vijaye Raji

Here's what makes Vijaye Raji the right person for this role.

Extensive engineering pedigree

Raji’s career began at Microsoft, where he spent nearly a decade building core systems like the Windows Application Framework, SQL Server modeling tools, and the Visual Studio editor. He then took on leadership roles at Meta (formerly Facebook), rising from software engineer to vice-presidential roles, including Head of Gaming, Head of the Seattle office, and finally VP and Head of Entertainment.

Founder and innovator

In 2021, Raji founded Statsig, translating his experience into a platform that democratized experimentation and data-driven decisions for engineers and product teams.

Fit for OpenAI’s ambition

In his new role, you’ll see him lead product engineering for ChatGPT, Codex, and associated systems—overseeing infrastructure, integrity, reliability, and experimentation pipelines. He reports to Fidji Simo, OpenAI’s CEO of Applications, who just joined from Instacart.

You’re looking at a blend of hands-on product innovation and large-scale engineering expertise being plugged into OpenAI’s mission.

What's new — and why it matters

What’s new Why it matters
Leader with entrepreneurial and scale-up credentials Raji understands both rapid startup growth and enterprise demands—key for reliability at scale.
In-house experimentation platform OpenAI inherits a world-class toolkit for rapid, data-led iteration across its apps.
Creation of new leadership structure With Raji as CTO of Applications and reshuffling of other exec roles, OpenAI aligns product, infrastructure, and enterprise under clear leadership.

This is expected to tighten integration between innovation and end-user value—making products like ChatGPT faster, safer, and more user-centric.

Details of OpenAI's Statsig Deal and Integration

  • The acquisition is all-stock, meaning OpenAI shares were exchanged rather than cash.
  • The USD 1.1 billion valuation reflects current market confidence and aligns with Statsig’s latest funding round.
  • Regional continuity: Statsig continues to operate from Seattle; its customers face no immediate disruption.
  • Integration pace: OpenAI plans a measured integration—keeping existing workflows intact while leveraging Statsig’s tooling.

What’s next under Raji’s leadership

We'll likely see rapid iteration features in ChatGPT and Codex, driven by experimentation frameworks. Core systems—reliability, performance, and trust—should improve, while OpenAI’s pipeline for turning model research into real-world products will tighten.

This move signals that OpenAI pivots from model-centric progress toward product engineering excellence. OpenAI's trajectory is now clearer. The company is investing heavily in turning models into widely usable, scalable applications. By acquiring Statsig and appointing Vijaye Raji, OpenAI has equipped itself with both toolset and talent to do that—even faster and more reliably.
