Spur was founded in 2024 by Yale graduates Sneha Sivakumar and Anushka Nijhawan. The startup uses AI agents to test websites for bugs. Users can set up tests using plain language, such as adding a product to a shopping cart or submitting a job application. The agent can then test these functions and help with debugging if necessary.
While there are many software testing startups have caught investors’ attention over the years, such as QA Wolf, Cypress, and Rainforest QA, Sivakumar says that Spur stands out because she and Nijhawan were the first to build a fully autonomous software tester back in 2023, when the two were college seniors. “A lot of the other agents weren’t advanced enough,” she said. “We were at the bleeding edge of what we were doing.”

Sivakumar and Nijhawan decided to put their experiences together and create Spur following their summer internships with Figma’s growth team and Google’s DeepMind team respectively. Sivakumar said that at Figma, she spent 30% to 40% of her engineering hours doing bug batching. “I just thought, ‘Why am I being paid to do manual QA? Why is there not a better way to do this?’” she said. The duo then put together their experiences as they began to work on Spur.
Spur was a member of Y Combinator’s Summer 2024 batch under its group partner Jared Friedman. Y Combinator later became one of the companies Spur later worked with, to test the YC application flow that sees millions of applicants every quarter. Other companies that partnered with Spur include Wander, which re-imagined their most business-critical, calendar UX from the feedback Spur provided, Norse Product, which used Spur to handle their regression testing, and Living Spaces which automated their entire regression suite with Spur in under a month.
