Swedish AI startup Klang raises €1.5M for DACH expansion

Swedish AI startup Klang, based in Helsingborg, has raised €1.5 million (15 million SEK) at a valuation of approximately €15 million.

Klang develops software that transcribes, summarizes, and analyzes conversations such as meetings and customer calls. The company reports about €1.8 million in annual recurring revenue (ARR) with a small team of five people. Klang has also released Pianissimo, an open Swedish transcription model based on Nvidia's Parakeet, which is about 60 times faster than the best open Swedish model and can run locally on standard laptops. The funds will be used to expand into the DACH region (following a Japan launch), invest in proprietary AI models, and hire about ten new staff for R&D and marketing.
