API-first business, anyone?

Hello everybody

I'd love to talk to some folks that work in API-first businesses. I'd like to understand more about metrics and tools used to support your company running.

I promise you, I'm not gonna try to sell anything.

I've been working as a software engineer for more than 8 years. Currently, I work in a big US company, so I can also provide help with something.

Thanks in advance.
