Klarent Secures €7.1 Million Seed Round Led by Mosaic Ventures

Klarent, a Zurich-based startup, has raised €7.1 million in seed funding. The round was led by Mosaic Ventures. The funding date is October 9, 2026. The round type is Seed. The currency is EUR.

What Klarent Does

Klarent is building an autonomous, agentic software testing platform for enterprises. Its AI agents use large language models to author test code, which then executes deterministically and repeatably. The platform includes a human-in-the-loop verification layer so customers pay only for verified outcomes.

Founded in 2023 by former Google engineers and formerly known as fore ai, the company serves enterprise clients such as JD Sports, NZZ and Sixt across retail, media, mobility and financial services.

The Investors

The round was led by Mosaic Ventures. Additional investors include Moonfire Ventures, Harris Barton, AngelInvest Ventures, and Jürgen Galler.

Why This Matters for Acquisition Watchers

Klarent operates in the growing market for AI-driven software testing, where enterprises seek to automate and accelerate quality assurance. Its agentic approach, combining LLM-authored test code with deterministic execution and human verification, addresses key concerns around reliability and cost. The company's client roster—JD Sports, NZZ, and Sixt—demonstrates traction across multiple industries.

For acquisition-oriented observers, Klarent's focus on verified outcomes and its enterprise customer base make it an attractive target for larger software testing, DevOps, or AI platform companies looking to add autonomous testing capabilities. The seed round, backed by Mosaic Ventures and a group of experienced investors, provides capital to scale its platform and expand its enterprise reach.
