What Gladia does
Gladia is a Paris-based AI audio infrastructure company, founded in 2022, that provides a production-ready speech-to-text (STT) and audio intelligence API for developers and enterprises building voice products. The company operates a horizontal platform serving contact center-as-a-service providers (Aircall, Livestorm), sales intelligence platforms (Attention, Carv), meeting assistants (Recall), media and video companies (VEED, Mojo), and voice agent developers, alongside enterprise customers such as Klarna, HeyGen, Citibank, Samsung, and Oracle. The platform serves 300,000+ users and 2,000+ enterprise teams with 2B+ minutes transcribed lifetime.
The core technology stack is built around Gladia's proprietary Solaria model family. Solaria-3, launched in 2025, achieves 9.6% WER on real English audio with particular strength in EN, FR, DE, ES, and IT, and supports 100+ languages with native code-switching. The platform exposes two primary APIs: a Real-time STT engine with sub-300ms latency and partial transcripts delivered in under 100ms, and a Batch/Async STT API for long-form audio. Bundled audio intelligence features — speaker diarization (powered by pyannoteAI and ranked #1 on market), named entity recognition, PII redaction, sentiment analysis, summarization, translation, and custom vocabulary — are included at no extra cost. An Audio-to-LLM pipeline with native or BYOM options converts conversations to structured outputs without requiring second-hop LLM calls.
Gladia monetizes through transparent usage-based pricing at $0.61-$0.75 per hour, a freemium tier offering 10 hours of audio processing, and Pro and Enterprise subscription tiers with annual contracts, custom SLAs, and EU data residency. Go-to-market is API-first and product-led, with self-serve signup at app.gladia.io, a developer community on Discord and GitHub, official Python and Node.js/TypeScript SDKs, and over 50 native integrations with voice stacks (Twilio, LiveKit, Pipecat, Retell, Vapi) and workflow automation platforms (Zapier, Make, n8n). Enterprise sales motion is layered on for accounts requiring SOC 2 Type II, HIPAA, ISO 27001, and GDPR compliance. In June 2026, OVHcloud announced exclusive negotiations to acquire Gladia to reinforce its AI Lab.

Revenue model
- Usage-based API pricing (per audio minute/hour): Gladia charges on a usage basis per audio minute or hour transcribed. Real-time and batch transcription are priced per unit of audio processed. Pricing is transparent and published, with rates varying by tier (Free, Pro, Enterprise). Features like speaker diarization and NER are bundled in base rates unlike competitors who charge add-on fees.
- Freemium / Free Tier: Gladia offers a free tier providing 10 hours of audio processing for developers to test the API before committing. This serves as a customer acquisition and activation funnel for the paid tiers.
- Subscription / Enterprise Plans: Gladia offers subscription plans (Pro and Enterprise) with dedicated features, support, and SLA guarantees. Enterprise tier includes named contacts, incident review, and predictable latency at scale. Pricing follows tiered subscription models alongside usage-based billing.
Pricing tiers
| Model | Billing | Price |
|---|---|---|
| Freemium | Monthly | Free tier with 10 hours of audio processing |
| Usage-based | Pay-as-you-go | Per-hour pricing for real-time transcription ($0.61-$0.75/hour) |
| Subscription | Monthly | Pro subscription tier with higher usage limits and support |
| Subscription | Annual | Enterprise tier with named support, custom SLA, and EU data residency |

- AssemblyAI: AssemblyAI is a direct STT API competitor offering real-time and async transcription with audio intelligence features (speaker diarization, sentiment, summarization). Competes head-to-head with Gladia for developer-led adoption and enterprise contracts.
- Speechmatics: Speechmatics is a UK-based STT provider offering multilingual speech recognition with strong European language coverage. Directly competes with Gladia in the same enterprise and developer segments with similar accuracy-focused positioning.
- Rev AI: Rev AI provides speech-to-text APIs with async and real-time transcription. Competes with Gladia for developer and enterprise transcription use cases, with hybrid human/AI transcription offering as a differentiator.
- Soniox: Soniox is an emerging STT API provider focused on multilingual real-time transcription. Targets similar developer and voice AI use cases as Gladia with competitive accuracy claims across 60+ languages.
Broad incumbents
- OpenAI Whisper: OpenAI's Whisper model (open-source and via API) is the dominant open-source and broad-availability STT alternative. AIMultiple benchmarks show GPT-4o-transcribe at 0.11 WER (best in class), setting competitive pressure on Gladia's accuracy and pricing.
- Google Cloud Speech-to-Text: Google Cloud Speech-to-Text is a hyperscaler STT offering bundled with the broader GCP AI/ML stack. Competes on scale and integration with Google Cloud, though typically with less focus on conversational/European language optimization than Gladia.
- AWS Transcribe: AWS Transcribe is Amazon's managed STT service bundled into the AWS ecosystem. Competes via integration with AWS contact center (Amazon Connect) and broader cloud spend commitments, though typically less specialized in multilingual real-time than Gladia.
- Microsoft Azure Speech: Azure Speech (part of Azure AI Services) is Microsoft's enterprise STT offering integrated with Teams and Dynamics. Competes via enterprise procurement and Microsoft ecosystem lock-in rather than developer-led adoption.
Emerging players
- Otter.ai: Otter.ai focuses on meeting transcription and AI note-taking, overlapping with Gladia's meeting assistant segment. Differentiates via end-user application rather than API infrastructure, serving a more vertical use case.
