If by successfully you mean time to market, for sure you are right.

C++ gives more return when you start to save in infra because you have a more efficient language, if coded properly. Same goes for Go vs Python.

The right tool for the right job. I would use (and will, I am on it) Django for a SaaS that I have for the backend. If things start to work relatively well, then, I will keep identifying, if there are, bottlenecks and migrate with a hybrid architecture parts of the workload to C++.

This allows me to save in infrastructure bills.
