Tonbo is a serverless database solution built on open formats, designed for the next wave of builders—startups, independent developers, and agent-driven teams.
Tonbo is a serverless, real-time analytical database for AI apps, built on open formats and designed for the next wave of builders—startups, independent developers, and agent-driven teams.
These teams need analytics that are lightweight, vendor-agnostic, and able to run where their apps actually live—on devices, in browsers, or in the cloud.
Instead of pushing data through heavy remote pipelines, Tonbo lets developers store, query, and analyze it directly where it’s generated. By running at the edge as well as in shared infrastructure, it cuts latency, reduces risk, and gives teams full control. As analytics shifts from large enterprises to fast-moving startups and agent-driven apps, Tonbo delivers the open, serverless stack built for this new era.
Headquartered in San Francisco, Tonbo was founded by Tzu Gwo, formerly with ByteDance’s infrastructure team, and Cream Tang, who previously worked at ByteDance and miHoYo.
