Treble raised 18 million dollars for a platform for simulating and testing voice AI

Icelandic company Treble raised 18 million dollars in an extension of its Series A round, led by Paladin Capital Group with participation from existing investors KOMPAS VC, Frumtak Ventures, EIC and Omega ehf. According to its own figures, Treble has thus raised a total of over 40 million dollars since its founding in 2020, including an investment of 12 million dollars in 2024. The company was founded by acoustic engineers Finnur Pind and Jesper Pedersen.

Treble operates a platform for simulating and testing voice AI that, according to the company, generates synthetic data for noise suppression, speech enhancement and model training, while also evaluating voice AI models under various acoustic conditions. Customers include Amazon and Logitech. Earlier this year, Treble announced a partnership with Hugging Face on a benchmark for speech recognition under realistic conditions.

According to the source, the platform is also used for virtual hardware prototyping — testing the acoustic properties of headphones and speakers or the ability of smart speakers to recognize commands depending on microphone placement. Treble is now expanding testing to smart glasses and wearable devices; founder Finnur Pind mentioned an interest in features such as “superhuman hearing”, meaning sound filtering in noisy environments.

Treble says it plans to expand its scope into physical AI, meaning robotics, automotive and drones. A representative of investor Paladin Capital Group said the value of the platform would grow as more products depend on understanding sound, adding that customers retain ownership of their models and products.
