Built on a gym floor, not in a pitch deck

I'm Jeremiah. I work in the fitness industry, on the operations side, and Churnline exists because I built these tools for a club I actually run before it ever occurred to me they were worth selling.

How this started

Nobody asked me to build a KPI tracker. I built one because the reports I could pull answered the wrong questions, and I wanted to know whether the club was really growing or just churning fast enough to look busy. The same thing happened with the decline report: I opened it one month, actually read it instead of skimming the total, and found members who had been training for months on a draft that stopped working in the spring.

The fixes weren't clever. Turn on the account updater. Stop retrying NSFs on a blind two-day loop. Flag the member at the front desk, where they're standing in front of you anyway. Split churn by tenure so the first-90-day problem stops hiding inside the average. None of it is novel — it's just work that nobody at an independent club has time to do, and that the big software vendors have no incentive to make easy.

Why I think this is worth your money

Most people selling to gym owners have never worked a shift in one. They come from software, they've read the industry benchmarks, and it shows the moment you ask them a specific question about how a member actually behaves at the desk. I can't offer you a decade of client logos. What I can offer is that I already know what your export looks like, what your staff will and won't actually do, and which of your problems is the expensive one.

Being early

Churnline is new. You will not find reviews, because there aren't any yet, and I'm not going to manufacture them. The trade I'm offering early clients is straightforward: the pricing is low for what the work is worth, the guarantee is real, and you get me directly rather than a support queue. In exchange I'd like the honest feedback and, if it goes well, permission to say your club's name.

If that's a fair deal, the fastest place to start is the leak calculator — it'll tell you in about thirty seconds whether this is worth a conversation.
