Klarent raises $8m to bring AI-written software tests to the US

9 October 2026: Klarent, a Zurich company that tests software with autonomous agents, has closed an $8 million seed round led by Mosaic Ventures, with Moonfire Ventures also taking part. The money is mainly meant to open a US presence.

Not yet independently verified. Rests on the company's own announcement; the lead investor's post and a second outlet were not reachable. A trade outlet reported the round as 7.13 million euros, which we have not reconciled with the $8 million the company states. We will update this when it can be confirmed, and remove this note.

Angel investors joined the round, among them Jürgen Galler, a former Google director, Harris Barton and AngelInvest Ventures. The company does not name the rest.

Klarent was founded by Asheem Panakkat, who is chief executive, and Momchil Ivanov, the chief technology officer. Both are former senior Google engineers who worked on the Lens and Shopping products. The company names JD Sports, the Swiss newspaper group NZZ and Sixt among its customers, and says it is now moving into banking and insurance.

The design choice that Klarent stresses is where the language model sits. Its agents use a large language model to write and adapt test code, but the tests themselves are deterministic scripts, so a run gives the same result each time. A human-in-the-loop service then checks each outcome, and customers are billed only for outcomes rather than for seats or runs. Chandar Lal of Mosaic Ventures put the idea this way: "using AI to write tests, not to run them."

Panakkat argues that testing becomes more important as AI produces more of the code that ships. Teams that already generate large volumes of code with assistants are the ones Klarent is aiming at, and the US is where it expects most of them to be.

Beyond the American expansion, the company plans to hire more engineers and to widen the product across web and mobile, so that one set of agents covers both kinds of application.

Our automated testing software category lists 21 products.

The company's announcement mentions no earlier funding, so this appears to be its first outside round. Pricing by outcome is unusual in a testing market that mostly sells licences or per-user plans, and buyers comparing vendors will want to ask how an outcome is defined and who decides it.
