Gladia's Meeting Transcription API

Gladia’s early wedge was not a new end user app, but a faster and more reliable speech layer for other products to build on. By starting with a modified Whisper based API in mid 2023, it could sell to meeting recorders and note taking apps that needed multilingual transcripts, speaker labels, and timestamps without running their own speech models or cloud inference stack.1 2 3 4 5

• The product launch timing mattered. Whisper was open sourced in September 2022, which let startups like Gladia turn a strong base model into a production API with better speed, packaging, and language handling for business use cases instead of training speech models from scratch.1 2 3
• The first buyers were infrastructure customers, not ordinary teams. A meeting app like Claap could send audio to Gladia and get back near real time transcripts with diarization and translation, then wrap that in summaries, searchable notes, and collaboration features under its own brand.2 4
• This put Gladia in a crowded but important layer of the stack. AssemblyAI sells a similar developer workflow for transcripts and downstream extraction, while Recall.ai captures the meeting itself and can plug in transcription providers like Gladia for note taking and recording products.5 6 7

The path from here is moving up from raw transcription into a fuller voice stack. As basic speech to text gets cheaper and more interchangeable, the winners are the APIs that combine accuracy, latency, multilingual support, and adjacent workflow pieces like meeting capture, analytics, and voice agents into one developer integration.5 6 7
