Working title: Ritmo-style copycat for Brazil and Mexico (working name)
Summary
BriefingVerified
Ritmo (solo founder, no coding background, founded Sep 2026; about 4-6 weeks old) matches active singles by sport. TrustMRR shows $4,195 MRR, 442 active subscriptions and $4,229 all-time revenue (RevenueCat-verified, Oct 21), with 1,492% month-over-month growth, and Marc Lou's newsletter named it the week's fastest-growing startup ('0 to $3,835 MRR in one month').…

Description
Original: iOS dating app positioned on shared active lifestyle, free access with Ritmo Pro and Boosts (TrustMRR), RevenueCat billing, founder with 1,300 X followers who says he cannot code. HBV version: a city-by-city 'training partner' app (running, padel, tennis, gym buddies) rather than pure dating, entering Mexico …

and Brazilian cities where padel/running clubs are booming, with a safety-first friend/group mode (lower moderation risk than dating). Faceless growth: SEO/GEO city pages ('parceiro de corrida em São Paulo'), AI-persona and club-account clips, partnerships with clubs via self-serve listing. Revenue: Pro subscription + boosts. Global Application: sports-partner matching per city and sport, same engine in every language. LatAm Version: Brazil and Mexico, padel/running/futevôlei, WhatsApp-group handoff after match, Pix/card web paywall. Key risk: two-sided cold start and trust & safety.
Target customer
Urban singles and fitness-minded 22-38 year-olds in Mexican and Brazilian metros
Pain
They exercise alone and dating apps ignore shared activities
Why this score
Why it scored lower: Cold start and trust & safety
MoatHypothesis
City-level density + club partnerships. Local club listings, city SEO pages and group formats can build density before generic dating apps adapt. Network effects are real but slow; defensibility is Hypothesis.

Jobs to be done
When I want to exercise regularly but I go alone and dating apps are not about activities, I want to find vetted partners for my sport nearby, so I can keep the habit and maybe meet someone.
