You don't need half of these services/tools. Especially when. You are building an MVP.

Your first version should be very simple with very few layers.

I couldn't think of any of those that aren't needed except for Segment. You definitely want monitoring and metrics in place before you launch otherwise you won't be able to figure out issues with your product.

And in the early days it's all about fast iterations.

Monitoring and metrics don't matter at launch when your scale is at most a handful of b2b clients. For an API-as-a-service? Maybe. But humans will be quick to let you know if they hit issues. More importantly, if you're fulfilling an important function for them, the number of 9s in your uptime is the least of their concerns.

This is exactly the trap the OP fell into.
