Dating for people who send

Your proj list says more about you than your bio ever could. The grades you chase, the styles you love, and the crags you travel for. That is compatibility data.

How it works for climbers

Connect your climbing profile. 27 Crags, Mountain Project, or answer the interest questionnaire. We pull your tick-list, grade range, style preferences, and session frequency. Nothing is shared raw - only signals.

The algorithm understands that climbing exists in layers:

Niche overlap > mainstream overlap

Both listing "rock climbing" as a hobby on Hinge? That tells us almost nothing. Both projecting 7a+ at the same crag in the Peak District? That is a signal.

Mainstream
"I like climbing"
Generic hobby → NicheWeight 0.12
Niche
Trad climber, VS-HVS, Peak gritstone
Specific style → NicheWeight 0.87

The algorithm knows the difference between "tried climbing once at a birthday party" and "drives to Fontainebleau twice a year." Tick-list depth, crag diversity, and session consistency turn a generic interest tag into a real affinity score.

What gets scored

Climbing style - bouldering, sport, trad, top-rope, speed, alpine. Your style mix is a personality fingerprint
Grade range - not just your hardest send, but where you spend most sessions. A V4 boulderer and a V4 boulderer have a shared experience a V10 crusher doesn't
Crag preferences - limestone vs gritstone vs granite. Indoor vs outdoor ratio. Local gym regulars vs weekend warriors
Session frequency - how often you climb, what time of day, whether you train or just climb for fun
Shared tick-lists - crags and routes you have both climbed, weighted by how obscure they are
Partner style - do you want a belay partner, a bouldering buddy, or someone who is happy to just share the van life?
Dealbreakers - indoor-only vs outdoor-only, competition climbing vs chill sessions, crack climbing enthusiasm (or horror)

Your tick-list is a dating profile

Except it actually means something.

"You both boulder V5-V6, you have both ticked 14 routes at the same three Peak District crags, your indoor-to-outdoor ratio is within 10%, and you both climb 3+ sessions per week. Style overlap: 84%."

Not "you both like the outdoors." The actual data.

The crag, not the gym

Climbing is one of the few sports where the venue is the experience. Two people who both travel to Magic Wood have more in common than two people who both go to the same chain gym. The algorithm weights shared outdoor crags significantly higher than shared gym memberships - because making the trip is the signal.

That said, if you are both regulars at the same wall on the same evenings, that is still a signal worth surfacing. The algorithm doesn't gatekeep - it just knows the difference.
