All of them copied 15.ai

ElevenLabs was a commercial version of 15.ai. It's crazy, because 15.ai could have had the venture-scale outcomes if he'd fundraised and turned it into a SaaS product. He was in the right place, right time, with tremendous attention, but missed the opportunity.

The other "labs" followed the trend. The {number}labs / {number}.ai domains all quickly got squatted.

I was in the same space and watched it happening. I launched FakeYou about the same time as 15.ai, but 15 had the backing of 4chan and a better model. I still made it to 7M MAU and a million in revenue despite that.

Just last year, Fish Audio picked up where 15.ai / FakeYou / UberDuck / Weights.gg left off and made it to $20M ARR, which is a lesson about abandoning under-served markets when you still have tremendous gravity.

SixSevenLabs btw seems really cringe, see https://www.67lab.ai/catalog/clawnexus
