We want to change how teams work with data

Our Story

While building Apple’s internal ML data management platform (SIGMOD ‘19), co-founders Yucheng, Ajit, and Rajat noticed that every team experienced the same challenges when experimenting with large scale data.

Seeing the opportunity to have wider impact across multiple industries, they founded XetHub in October 2021 to approach the problem from a new direction. Our vision is to enable delightful collaboration on code and data at any scale.

Yucheng Low
CEO & Co-Founder

Yucheng was a co-founder and the Chief Architect at Turi, a ML startup acquired by Apple in 2016. At Apple, he worked on different parts of the ML platform stack ranging from storage to inference. His native language is C++, but Rust is rapidly becoming his new favorite. In his spare time, he bikes long distances and trains for triathlons. As of 2022 he still does not have a driving license.

Ajit is a co-founder at XetHub. His two decades of engineering experience included stints at Inktomi, Amazon (where he was part of the founding EC2 team in 2006), Facebook, and Apple. He has an entrepreneurial habit, having founded two other startups prior to XetData, one of which was acquired by BlueKai/Oracle. When not hacking, Ajit can be found savoring fine cocktails in Seattle bars and enjoying the beauty of the Pacific Northwest (hiking in the summer and skiing in the winter).

Rajat is a co-founder at XetHub. Rajat has spent most of his 20 years in industry building large scale distributed systems at Microsoft, AWS, and Apple. He joined Yucheng at Turi as the first employee, and has been building systems for ML ever since. At Apple, Rajat started and led the data platform team, presenting the group’s work at SIGMOD `19. At XetData, he wants to code more, but instead spends most of his time talking with customers and building cool demos. Outside of work, you'll find him spending time with his two small children, watching sports (NBA, NFL) or bad movies, or planning his next novice woodworking project.

Hoyt studied physics, statistics, and machine learning before joining Turi in 2013 as an early employee to work on scalable machine learning solutions aimed at non-ML developers. After Turi was acquired by Apple, he worked on core ML libraries at Apple, including CoreML and CreateML. His main interests include optimization, algorithms, ML, and scalable data processing. At XetHub, Hoyt is often writing low-level Rust code in our git extension and looking for ways to squeeze out more performance. Outside of technical work, Hoyt enjoys backpacking, hiking, mixology, coffee, and artistic metalworking.
