I am one of those building an analytics platform.

The reason: out of the tens of projects I tried, this is what customers wanted and were willing to pay for.

It's not even easy to build, it's a lot harder and more complex than some niche-specific tools.

I still do have many other projects, and constantly try new stuff, but this is what worked for me, it was not really my choice, it just happened.
