About Shuhao Zhang
Shuhao Zhang is a cofounder of TinyFish Inc., a company that works on web search and information retrieval for AI agents. At Alibaba Cloud's Apsara Conference 2026 he appeared as Cofounder and CPO of TinyFish. He spoke about engineering moving beyond writing code as AI agents take on more of the work, and about how TinyFish and Alibaba's Qoder coding tool work together.
Coverage of the Lightsage round lists him as TinyFish's COO, so his exact title differs between sources. This page does not cover his education or earlier roles, because we found no reliable public source for them.
The only angel investment we could confirm is Lightsage. Shuhao Zhang is named among the individual investors in its seed round in a Grishin Robotics newsletter. Press coverage of the same round names "Shuhao" as TinyFish's COO. We found no public angel portfolio page, Crunchbase profile or personal statement about his angel activity.
Lightsage, formally API-Rex Inc., announced a $4M seed round on September 8, 2026. Nexus Venture Partners led it. Other participants included operators from Postman, Apollo, DocuSign, Resend, Firecrawl and Daytona.
Lightsage is based in San Francisco. It helps software companies test how AI coding agents discover, evaluate and integrate their products, and it flags failures in documentation, authentication, APIs, SDKs and MCP servers. Its early users include Reducto, Daytona, Firecrawl, Rime and TinyFish.
We found no public statement from Shuhao Zhang on check size, stage or sectors. His one confirmed investment is a seed-stage AI developer-tools company. His operating work at TinyFish is in AI agents and web infrastructure. Founders building in those areas may find him relevant, but that is an inference from his background and not a stated thesis.
