Ask HN: How to find a buyer for cycling power meter analytics software?

A few years ago we've built an app for analytics cycling power meter tracks. It is available at strivemax.com

Because we can't provide enough attention to support and grow this service, we would like to find a potential buyer for it. We currently have a few dozens paying customers.

We tried to connect with some of the power meter producers but with no luck for now.

What would you recommend to do to find a buyer for this kind of software?
