Otter.ai got there first, launching in 2016 — that's 1 year of extra runway. PolyAI didn't arrive until 2017. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

Otter.ai has about 150 employees; PolyAI has about 100-500. A bigger team usually means more revenue or heavier VC backing, but in AI, small teams can build at massive scale.

Yes — they're direct rivals. Both Otter.ai and PolyAI compete in AI Audio, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
