About KugelAudio
Summary
KugelAudio builds a text-to-speech API for enterprises that need natural-sounding voice output across 39 languages. The model runs on-premises or in a European sovereign cloud, is fully GDPR compliant, and delivers first audio in under 50 milliseconds. It targets use cases where standard TTS fails on real-world data: IBANs, phone numbers, postal codes, dates, and addresses, replacing generic cloud TTS services that lack multilingual fidelity and EU data residency.
Business model
A free tier plus paid plans billed by usage, with EU sovereign cloud included on every plan for EU/EEA customers without an enterprise contract.
Go-to-market
Enterprise buyers in regulated or multilingual markets adopt the product through a self-serve API with a free start and no credit card required, scaling into paid plans as usage grows.
