> Building and maintaining a good CAPTCHA service is both hard and requires a high level of continuous development, since every day people are waking up and trying to figure out how to break it. This means almost every company that tried building their own in the past has switched to either hCaptcha or Google, since it is not practical for even large companies to maintain their own solution these days.

I’m under the impression that the bottleneck isn’t “high level of continuous development” so much as it is just having a large enough data set of Internet activity to conduct statistical analyses on. Cloudflare and Google are obviously in a good position for this, since a significant amount of Internet traffic goes through them. But I can’t create a startup to invent the next Captcha unless I magically discover a flash drive containing a giant corpus of HTTP requests made by billions of modern devices around the planet.
