“Why would OpenAI spend $1.1 billion on a product development platform?”
The answer lies in one man: Vijaye Raji, founder of Statsig, now stepping in as OpenAI’s CTO of Applications.
Why Vijaye Raji Matters to OpenAI
Vijaye Raji isn’t just another high-profile hire. He’s a hands-on builder who has led both scrappy startups and massive consumer teams.
Now, he takes charge of OpenAI’s Applications division, home to ChatGPT and Codex, reporting directly to Fidji Simo, CEO of OpenAI Applications.
The timing is crucial: OpenAI needs more than great models; it needs reliable, user-friendly products that scale to hundreds of millions.
As Fidji Simo put it: “Vijaye has a remarkable record of building new consumer and B2B products at scale… his leadership will help turn that progress into safe applications that empower people with many new tools.”
10 Lesser-Known Facts About Vijaye Raji
1. He studied engineering at Pondicherry University
Raji earned a Bachelor of Engineering degree from Pondicherry University in India in 1999. It also highlights OpenAI’s growing diversity of leadership, with voices shaped by global educational paths rather than only Ivy League institutions.
2. He started his career at Microsoft in 2001
Raji worked for nearly a decade at Microsoft, building developer tools such as Visual Studio Editor and frameworks that Windows engineers still rely on. This gave him a deep respect for infrastructure, the kind of foundation OpenAI needs as its products reach hundreds of millions of users.
3. He helped build Messenger for Windows
Long before WhatsApp or iMessage dominated, Raji worked on Messenger, one of the first global chat apps. That early exposure to real-time communication at scale looks like a training ground for today’s ChatGPT rollout, where reliability and speed are non-negotiable.
4. He led the creation of Facebook Marketplace
Marketplace, now used by over a billion people worldwide, started under his watch. He understands how to connect people and businesses inside a platform. For OpenAI, this could mean creating new ways for users, developers, and enterprises to interact with AI tools.
5. Head of Facebook Gaming
As VP of FB Gaming, Raji oversaw an audience of 700 million gamers. He helped push innovations like streaming and instant games. That experience hints he could extend ChatGPT beyond text into interactive, community-driven applications.
6. Scaled Facebook Seattle from a handful to 5,000 staff
Raji isn’t just a product builder. He’s an organizational builder. OpenAI is hiring aggressively, especially in Seattle. His ability to grow teams fast while keeping execution disciplined could turn that office into OpenAI’s second HQ.
7. Statsig processed 1+ trillion events per day
Under his leadership, Statsig became a platform trusted by Atlassian, Notion, and Bloomberg to run massive experiments. This shows Raji’s comfort with data at an enormous scale. It’s a skill OpenAI will need as it personalizes AI safely for millions of users.
8. He is known for inspiring loyalty among his teams
Former colleagues even joked about making “Vijaye Raji body pillows” to show their affection. This kind of trust-driven leadership matters at a time when OpenAI faces fierce competition for top engineering talent.
9. He built Statsig’s DNA: ship fast, measure, iterate
Statsig’s motto was “ship fast, measure, iterate.” By bringing this DNA to OpenAI, Raji will ensure ChatGPT evolves more quickly by rolling out features to test, learning from feedback, and improving before competitors catch up.
10. A family man and teacher
Beyond work, Raji volunteers to teach computer science to elementary school children. This long-term interest in education could influence OpenAI’s future direction in AI-powered learning tools.
What This Means for OpenAI
The $1.1B OpenAI acquisition of Statsig wasn’t about just buying software; it was about buying a method. With Vijaye Raji as the new CTO of Applications, OpenAI is betting on:
- Faster product launches via feature flags and A/B tests.
- Enterprise trust with compliance-ready experimentation.
- Personalization at scale without sacrificing safety.
For users, the impact may be subtle but profound. In the next year, expect ChatGPT to evolve quietly but steadily through smarter updates, fewer regressions, and safer rollouts.
Conclusion
For OpenAI, the appointment of Vijaye Raji is a shift from an era of breakthrough research to one of disciplined product execution.
Raji’s background shows he thrives in this exact role of bridging infrastructure with user experience.
As Raji himself said on joining OpenAI: “This is an extraordinary opportunity to bring my experience scaling products to a mission I deeply believe in: advancing AI in ways that are reliable and beneficial to people everywhere.”
And that’s the key.
In a world racing toward AI, the winner won’t just be the lab with the best model. Instead, it will be the team that ships it best.
And Vijaye Raji may just be the person to make sure OpenAI gets there first.
