A software for managing BJJ and martial arts academies that it's both easy to use and have everything they need like assistance tracking, payments, communications, etc.

It's called MatGoat[1], and it's going quite well so far. Nowadays I'm working more on the marketing/sales side.

Keep working on MatGoat (https://matgoat.com/en/) - management software for Brazilian Jiu-Jitsu and other martial arts' academies.

I train BJJ and kept hearing the same pain points from academy owners regarding attendance tracking, communications, missing payments, etc.

So I built a tool for martial arts academies in 2024 with belts progression, automated payments, attendance tracking, and a tablet check-in system. Nowadays I'm still onboarding new academies every week and working a bit more on the marketing side to keep growing.

Amazing to see such a long tenure in that competitive market. Thanks for sharing!

I wonder, apart from the normal exposure/distribution on App Store, what are the main strategies you've used for marketing?

Building MatGoat (https://matgoat.com) - management software for Brazilian Jiu-Jitsu and other martial arts' academies.

I train BJJ and kept hearing the same complaints from academy owners regarding attendance tracking, comms, missing payments, etc.

So I'm building a tool for student tracking with belts progression, automated payments, attendance-based promotion criteria, and a tablet check-in system.

Focusing on Spanish-speaking markets first since it's completely underserved. Currently onboarding early academies, and will market it in the US/UK soon.

New comment by josem in "Why parenting makes you human"

Author here :)

I’m sorry this article felt that way. My intention was not so much saying that you cannot be in touch with that human side if you’re not a parent. It was more about celebrating the good parts of parenting when it comes to how they change you.

That said, I can understand how this could be seen how you shared it, thank you for your thoughts!
