Not sure where to take my SaaS app - partner? sell?

Hello IH, I have a SaaS app that has been around for about 4 years. It has been sitting between $300-$1100 revenue for the past two years (seasonal - it's a cycling training web app). I've been feeling some burnout on it over the past year. So, I'm looking to partner up with a co-founder (or let it go to the right person who wants to take it somewhere).

The right co-founder would need to be fairly knowledgeable or interested in road cycling. It's built on Rails, so I'd say that's probably a requirement if you're more interested in development (but I'm new to anything entrepreneurial or development). A mix of development and marketing would be ideal.

I would love to share more and talk details over email!
