That said, there's more commonalities between HyperTrack and TalkJS than just that we're both SaaS - both products help you build a marketplace type platform faster. HyperTrack makes it easy to build location sharing between your users, we make it easy to build message sending between your users. Most SaaS products, even most chat products, don't have that dynamic. You can't use Intercom or Slack to build user-to-user messaging on your platform, just like you can't use Google Maps or Mapbox to (easily) build realtime location sharing on your platform.
About your Stripe example: I agree about Stripe in general, but as a matter of fact their Stripe Connect product happens to be a miraculously great fit, becaue it's a service for user to user payments. HyperTrack + Stripe Connect + TalkJS means you can have a functional Uber with all bells and whistles in just a few days.
I felt it was on-topic because this article isn't just about HyperTrack, it's about building an "Uber for X" in a single day.
