Gabor Cselle, known for his work as a serial entrepreneur and former CEO of Pebble, has joined OpenAI to work on a confidential project, marking another pivotal move in his tech career. Cselle, who has been with OpenAI since early October, confirmed his employment in a post on X. “Will share more about what I’m working on in due time,” Cselle wrote, hinting at an exciting new venture but leaving details under wraps.
Cselle’s journey reflects extensive experience with big tech and innovative startups. His first Y Combinator-backed startup, reMail, was an early mobile email solution acquired by Google. Later, he launched Namo Media, a native advertising startup that sold to Twitter, where he subsequently worked as a group product manager, overseeing the home timeline and user onboarding features. After Twitter, Cselle held a directorial role at Google’s Area 120 incubator, focusing on experimental projects and spin-offs.
The Rise and Fall of Pebble (formerly T2)
In 2022, Cselle launched Pebble with Michael Greer, the ex-head of engineering at Discord, aiming to create a platform that prioritized safety and moderation. Initially named T2, Pebble was designed as a competitor to X (formerly Twitter) and developed a small but loyal following. The platform gained traction with angel funding from high-profile investors, including Android co-founder Rich Miner. Despite the promising start, Pebble faced challenges with sustained user growth and eventually shut down in October 2023. The project was later revived as a Mastodon instance, pivoting to align with the growing trend of decentralized social networks.
Cselle’s Exploration in Generative AI at South Park Commons
Before joining OpenAI, Gabor Cselle worked at South Park Commons, an accelerator known for nurturing innovative tech initiatives. During his time there, Cselle delved into generative AI, producing various prototypes, including a project inspired by the once-viral HQ Trivia app. His work at South Park Commons demonstrated his adaptability and willingness to explore the rapidly expanding AI landscape, making him a fitting recruit for OpenAI’s cutting-edge projects.

Cselle’s hiring at OpenAI coincided with another significant industry move: Alex Rodrigues, the founder of Embark, joined Anthropic as an AI safety researcher. Rodrigues, whose autonomous trucking company merged with Applied Intuition in a fire sale, will now contribute to Anthropic’s focus on AI safety and ethics. His transition highlights the intensifying competition between leading AI research labs like OpenAI and Anthropic as they vie for top talent to advance their respective AI agendas.
The Future of Cselle at OpenAI
Though Gabor Cselle has not disclosed specifics about his role at OpenAI, his past experience suggests he may focus on product development within OpenAI’s consumer-facing applications or safety frameworks. Given OpenAI’s recent ventures into expanding ChatGPT and its other generative AI products, Cselle’s expertise could significantly enhance OpenAI’s approach to user-centric and ethical AI solutions.
Both Cselle and Rodrigues’ transitions underscore a trend: prominent leaders from tech and autonomous industries are bringing their insights into the AI domain. As OpenAI and Anthropic continue their talent acquisition, the AI field is poised for even more dynamic developments, with safety, user engagement, and ethical standards becoming central themes in the race for AI innovation.
