In the age of AI-generated software, developers still need to make sure their code is clean. right there TestSprite wants to help
The Seattle startup announced $6.7 million in seed funding to expand its platform that automatically checks and monitors code written by AI tools such as GitHub Copilot, Cursor and Windsurf.

TestSprite’s autonomous agent integrates directly into the development environment, running tests throughout the coding process rather than as a separate step after deployment.
“As AI writes more code, validation becomes a barrier,” the CEO said Yunhao Xiao. “TestSprite makes testing autonomous and continuous, solving with AI speed to match.”
The platform can create and run front-end and back-end tests during development to ensure AI-written code works as expected, AI IDEs (Integrated Development Environments) help fix software based on TestSprite’s integration testing reports, and can continuously update and rerun test cases to monitor deployed software for ongoing reliability.

Founded last year, TestSprite says its user base has grown from 6,000 to 35,000 in three months, and revenue has doubled every month since launching its 2.0 version and new Model Context Protocol (MCP) integration. The company employs about 25 people.
Xiao is a former engineer at Amazon and a natural language processing researcher. He also co-founded TestSprite Rui LeeA former Google engineer.
TestSprite does not compete with AI “Seattle startup Test Sprite” Coding Copilots, but complements them by focusing on continuous “Seattle startup Test Sprite” validation and test generation, Xiao said. Developers can trigger tests using simple natural-language commands like “test my payment-related features” directly inside their IDE.
The seed round was led by Bellevue, Wash.-based Trilogy Equity Partners, Techstars, Zinq Capital, MiraclePlus, Hattrick Capital, Baidu Ventures and Ezcase Capital Partners with participation. Total funding to date is approximately $8.1 million.
