The cost saving is literally the difference between being profitable or not for us," emphasizes Mark. "But beyond the economics, AssemblyAI gave us something invaluable: peace of mind. We can focus on building our product instead of worrying about infrastructure limits.
Mark Barbir
CEO, Earmark
AssemblyAI has a real high-touch personal service. It's a great partnership and we're very collaborative and get to test new AI models early and work together. And AssemblyAI is really pushing boundaries, helping us create a well-rounded conversation intelligence platform.
Tom Lavery
CEO & Founder, Jiminny
On 10 out of 10 onboarding calls, our customers are at some point telling us 'wow that insight was crisp'—and that's because of the accuracy we're getting from AssemblyAI.



Jake Cronin
Co-founder and CEO, Siro
The transcript quality is critical, both for user perception and our AI models. Once you lose trust in transcript accuracy, you erode trust in the product. For text classification, phrase detection, and agent evaluation, the language has to be correct - otherwise, the whole system falls apart.
Dr. Shane Lynn
CEO, EdgeTier
The 30-40% reduction in speech-to-text errors has significantly improved our production efficiency and client satisfaction. We've achieved industry-leading word error rates for non-English audio, which is critical for serving our enterprise clients.
Ebru Yildirim
Founder and CEO
If you have an hour of content, the difference between 99% accuracy and 97% accuracy, it's a lot of time for that person to review. So you could cut down their workflow from taking half an hour, taking 20 minutes, taking 15 minutes– it's huge, right?
Joshua Grossberg
CTO, Kapwing
The speed difference is immediately noticeable - our users see their conversations transcribed almost instantaneously. It feels so much more responsive than what we were using before.
