Gladia

Product overview

Gladia is a Paris-based company that provides a speech-to-text API for developers and businesses who need to transcribe audio in real time or from recordings. The API supports over 100 languages with native code-switching (detecting when speakers switch languages mid-sentence), speaker diarization, sentiment analysis, named entity recognition, and translation. The real-time engine delivers results with latency under 300 milliseconds. Founded in 2022 by Jean-Louis Quéguiner (former VP of AI at OVHcloud) and Jonathan Soto (former VP of Engineering at Sigfox), the company started because Quéguiner was frustrated that no transcription service could accurately handle his French accent. Gladia has raised $20.3 million in total, including a $16 million Series A led by XAnge in 2024, with participation from Sequoia Capital, Illuminate Financial, and XTX Ventures. The platform is used by over 2,000 enterprise customers and 300,000 users, including Attention, VEED.IO, Sana, and Circleback. Gladia's proprietary Solaria model is designed to reduce hallucinations on noisy real-world audio. The company does not use customer audio to retrain its models. All data hosting is GDPR-compliant with EU and US hosting options. KEY FEATURES: - Real-time and asynchronous speech-to-text in 100+ languages - Sub-300ms latency with native code-switching detection - Built-in audio intelligence: diarization, sentiment, entity recognition, translation - GDPR-compliant data hosting with EU and US regions - Single API compatible with all tech stacks including SIP, VoIP, and telephony protocols
