This seems ok given that the startup has generated approximately $60,000 in stripe revenue.
I would try to reduce costs in those Heroku workers... $175/month seems steep.

By the way, your use of Heroku makes total sense given that you're basically alone, I hope that the lock-in won't be too difficult to overcome when moving away from it.
I also want to say that your site has a great design. Are you doing that yourself or would you mind sharing the service you're using?
It may pay off for certain organisations, but it currently a quite a rabbit-hole, with a constantly changing landscape, complexities of its own, etc.
