Iceland's Treble raised an $18 million Series A extension led by Paladin Capital Group, with KOMPAS VC, Frumtak Ventures, EIC and Omega ehf participating, bringing total funding past $40 million. The platform simulates acoustic environments to generate synthetic data for speech enhancement and noise suppression, evaluate voice models across conditions, and let hardware makers virtually prototype acoustic performance. Amazon and Logitech are customers; co-founder Finnur Pind frames the pitch as moving audio AI past internet-scraped recordings.
