Contact CNX BJJ

Whether you run a gym, train on the mats, or want to work with us, we would love to hear from you. CNX BJJ is based in Chiang Mai, Thailand, and we read every message that comes in.

Get in Touch

CNX BJJ exists to map the Brazilian Jiu-Jitsu scene across Thailand, from the academies in Chiang Mai to the busy mats of Bangkok and the training camps on the islands. That work is never finished, and the most useful pages we publish are the ones shaped by people who actually train here. If you have something to share, a message from you genuinely helps.

You do not need a formal reason to write. A quick note pointing us toward a gym we have missed, a tip about a class that has changed, or simply a question about training during a visit are all welcome. The more local knowledge we gather, the more useful our guides become for the next person searching for a place to roll.

Reasons to Reach Out

Most of the messages we receive fall into a few clear categories. Knowing which one fits your situation helps us reply faster and point you to the right person.

Gym featuring and partnerships

If you own or coach at a gym in Thailand, let us know it exists. We build our city guides independently, but a short introduction with your location, head instructor, and schedule makes it far easier for us to research and feature you accurately. We also talk to event organisers, training camps, and brands that serve the local BJJ community about genuine partnerships that benefit readers.

Corrections to a guide

Details change. A gym moves, a price goes up, an instructor earns a new belt, or a class disappears from the timetable. If you spot anything out of date or wrong in one of our guides, tell us. Include the page address and the specific detail, and we will check it against a reliable source and fix it. Keeping our information honest is the whole point of the site.

General questions

Planning a trip and unsure which gym suits a beginner? Wondering about drop-in fees, gi rules, or what to expect at your first class in Thailand? Ask away. Many answers already live in our beginner guides and city pages, but if you cannot find what you need, send a message and we will help where we can.

Contact Details

The quickest way to reach us is by email. We are a small team based in northern Thailand, so please allow a few working days for a reply. Corrections to live guides are always handled first.

Frequently Asked Questions

Send us a short message with your gym name, location, head instructor, and a link to your schedule or social pages. We build our city guides independently and visit or research every gym we list, so a message helps us put you on our radar. Featuring is editorial and free, and we cannot promise inclusion or a publication date.
Email us with the page URL and the specific detail that is wrong, such as an outdated mat schedule, a closed gym, a changed price, or an instructor's belt rank. Accuracy matters to us, so we check every correction against a reliable source and update the page if it checks out.
We do not sell advertising or paid placements in our gym guides or reviews. Rankings and recommendations are kept independent so readers can trust them. If you want to explore a genuine partnership, get in touch and we will tell you honestly whether there is a sensible fit.
Our city guides for Chiang Mai, Bangkok, Phuket, and the wider country are written to answer exactly that. Start with the city you are visiting, and if you still have a specific question about drop-in fees, gi rules, or class times, send us a message and we will help where we can.
CNX BJJ is run by a small team, so replies usually take a few working days. Corrections to live guides are treated as a priority, while general questions and feature suggestions are handled in the order they arrive.
