Hi, I'm Benjamin.

I've always had a lot of climbing friends — across different gyms, different schedules, different chat groups. For years I watched the same pattern repeat: someone asks "who's climbing today?" in a group chat, three people respond hours later, and the session either never happens or you miss it because you weren't checking your phone.

The climbing community is incredible when you're at the gym. The problem is getting there together. I lost touch with friends not because we drifted apart, but because we had no simple way to stay in sync.

I thought about this for years. An app that doesn't try to be a social media platform or a training log — just a cleaner way to coordinate climbing with the people you actually climb with. Something that replaces the group chat, not adds another one.

Eventually I stopped waiting for someone else to build it. I'm a physicist by training, which means I'm stubborn about solving problems properly. I teach climbing, which means I understand the community from the inside. And I code — obsessively — which means I could actually build the thing.

So I did. ClimbSync is that app. It's early, it's evolving, and it's built by someone who actually needs it every week.
