> Earlier this year we started using Antithesis, an end-to-end automated testing platform, to fill those gaps. We’ve become huge fans of the service (and are now leading their next funding round! More on that later), and part of the point of this post is to explain why.

Having a good first customer helps with designing a better product ... and can help with funding too.

I really enjoyed this, and following the link to the Antithesis talk was really interesting as well [0] as it goes in to some of the pitfalls of random testing and some of the properties that you'd like out of a good test system. This is a field I'm really interested in but it seems hard to grasp.
