OpenAI shuffles its executive roles and acquires product analytics company Statsig for $1.1B, with Statsig CEO Vijaye Raji becoming OpenAI's CTO of Applications
It was a big weekend for the ChatGPT-maker. … OpenAI has started to build out its Applications team under Fidji Simo …
The VergeHayden Field
Context & Ripple Effects
OpenAI had already put Fidji Simo in charge of business and operations as CEO of Applications, with responsibility for sales, marketing, and finance in an applications leadership role. This acquisition adds product-development infrastructure and an executive directly beneath that organization.
The move gives concrete shape to the Applications buildout that followed Simo’s arrival, shifting attention from the organizational announcement to the tooling and leadership needed to operate consumer and business products.
First-order effects
Statsig becomes part of OpenAI in a $1.1B acquisition, bringing its product-analytics capabilities in-house.
Former Statsig CEO Vijaye Raji becomes CTO of Applications, expanding the technical leadership of Simo’s applications organization.
Second-order effects
OpenAI’s Applications group can more tightly connect product experimentation and analytics with its own product roadmap, rather than treating those functions as an external vendor relationship.
The deal makes product analytics talent and infrastructure more strategically relevant to AI companies building application businesses, not just to conventional software product teams.
Third-order effects
If OpenAI continues to staff and equip Applications as a distinct unit, leading AI labs may increasingly separate research, compute, and safety from the operating disciplines of shipping and improving products.
That division could make distribution, rapid iteration, and user feedback a more durable competitive layer alongside model capability—an outcome that depends on whether AI products sustain broad commercial use.
The trend: AI labs are evolving into application operators, using dedicated leadership and product infrastructure to turn model advances into repeatable user-facing businesses.

I'm excited to share that I'm transitioning to a new role as CTO of B2B Applications at OpenAI. A big draw for me to join OpenAI was the opportunity to have a huge impact on the world across multiple industries. We have amazing models that are winning math olympiads and coding …
Congratulations @vijayeraji and the entire @statsig team on a huge milestone to join forces with @openai! It's been a highlight to work alongside you all over the last 4 years. [image]
Congrats to my partner @mvernal on leading this Series A investment — and to @vijayeraji on building an amazing team, very cool product, and their acquisition by @OpenAI!
Statsig was acquired by OAI in a $1.1B all-stock deal. Notably, they announced a $100 million Series C at the same $1.1B valuation from Iconiq just a few months ago, in May 2025. Wonder what prompted management to sell after the recent large equity raise.
@ArfurRock OpenAI CEO of Applications wanted to poach Statsig CEO (former Meta colleagues), but didn't want to ruin optics. So they brought the entire team. Doesn't look like team is joining OpenAI... they'll “continue operating independently.” https://x.com/...
.@Statsig is joining @OpenAI. Over the past 4.5 years, we've built something special at Statsig: a platform that the world's best technology companies rely on to build fast and make smart decisions. We're going to join forces with OpenAI to vastly expand our mission, while
Congratulations to Vijaye Raji and the @statsig team for this successful milestone and the exciting next chapter with OpenAI. It has been a privilege to have been a part of this journey from Day 1, and we are looking forward to more game-changing products and successes from

💥 I'm starting something new inside OpenAI! It's called OpenAI for Science, and the goal is to build the next great scientific instrument: an AI-powered platform that accelerates scientific discovery.
I'll simultaneously begin working with @SebastienBubeck and the synthetic data team at OpenAI as an AI researcher to learn the craft. I'm grateful to him and his team for being willing to mentor me, and I'm eager to prove worth their time and effort!
I'm able to do this because the product and design leaders at OpenAI are amazing, and now are complemented by @fidjissimo beginning her role as CEO of Applications. OpenAI's products have been my life since I joined, and they're in great hands.
We'll look to hire a small team of academics that are (i) world-class in their field; (ii) completely AI-pilled; and (iii) great science communicators. Paired with a small team of researchers, we want to prove that AI models are ready to accelerate fundamental science—and accele…
I wasn't clear enough with my last post but this is clearly just a play to steal taxpayer dollars from NSF, NIH, DoE, DoD, etc. — AI cannot do scientific discovery. It cannot test hypotheses. It cannot find real connections. — It is incapable of critical thinking or logic. …
