Who's Actually Behind Your Gym's Marketing? How to Verify an Agency Before You Trust Them
It has never been easier to look like a marketing agency. A polished website takes an afternoon. Testimonials can be invented. Case studies can be "illustrative." Some agencies have no owner you can name, no face you can find, and no way to reach a real person until after you've paid.
As a gym owner, you're not just buying a website. You're handing someone your Google Business Profile, your reviews, your leads, and your reputation in your town. So before you trust anyone with that, including me, run them through the checklist below.
The six-point verification checklist
1. Can you find a real name and a real face?
Not a logo, not "our team," not a stock photo. A person who owns the business, with their name on it. If something goes wrong, you should know exactly who is accountable.
2. Can you watch real clients talk, in full?
A two-line quote with a first name is easy to fake. A gym owner on video, under their own name and gym name, talking for more than a few seconds, is not. The best proof is a full conversation you can watch end to end, not just a highlight clip.
3. Can you reach the owner directly, before you buy?
Try it. Send a DM. Send an email. Ask for a quick call. How fast a real person answers before you pay tells you a lot about how fast they'll answer after.
4. Are they actually in your world?
Anyone can pick "BJJ gyms" as a niche off a list. Look for a real history: training, competing, being known in the community. Someone who's on the mats understands why your trial students are nervous, why kids programs matter, and why culture keeps members.
5. Are the results specific, and stated honestly?
Real results come with real context: what was built, over what time frame, for what kind of gym. Be careful with anyone who guarantees a number of leads or students. Nobody honest can promise that. They can promise the system and show you what it has done.
6. Do you keep what's yours if you leave?
Your domain, your Google Business Profile, your reviews, and your rankings should belong to you. (Here's who should own your gym's website and Google profile.)
The real filter
Almost any agency knows how to do this work better than you'd do it on your own. That's not the hard part.
The hard part is finding someone with a real track record in your industry, who has been in the community for years, and who is willing to put their face on it publicly where you can verify it. Most new agencies can't check all three boxes. That's the filter that actually separates them.
Run the checklist on me
I'd rather you verify me than take my word for it. Here's everything, in one place:
- Who I am: Tanner Sullivant. Military veteran, international competitor, and a brown belt with ten years on the mats. I started Grapple Growth in 2023 after dropping into gyms while traveling and seeing great gyms that were invisible online. The full story is on my About page.
- My face, my training, my work: Instagram at @tsullybjj (me and my jiu-jitsu) and @grapplegrowth (the business).
- Real clients, on video, in full: my full interview with Don Dees, owner of Modern Martial Arts in Clarksville, Tennessee. It's a real conversation about what changed at his gym, lightly trimmed, not a scripted ad. There's also a 2-minute highlight version.
- Everything else I publish: the Grapple Growth YouTube channel.
- Results, with context: the Results page, where every number comes from a current client, and the Georgia case study.
- Reach me directly: DM me on Instagram, email grapplegrowth.co@gmail.com, or book an optional call. Prefer not to talk yet? Watch the 5-minute breakdown first. No sales call required.
Why I put my face on it
The jiu-jitsu world is small. The people I train with, compete against, and learn from know who I am. If I did bad work for a gym owner, it wouldn't stay quiet, and it shouldn't.
That's the point. My name and my reputation in the sport are on every site I build. I hold every one to the same standard: if my dad opened a gym tomorrow, would I build it this way for him? If the answer is no, it doesn't ship.
A fair note on faceless agencies
Not every agency without a public face does bad work, and a big team can be a good thing. But when you can't verify who's behind something, you're relying on trust you haven't been given a reason to have. For something as personal as your gym, you deserve to know exactly who you're working with.
Quick answers
How can I tell if a marketing agency's testimonials are real?
Look for testimonials you can verify: video from a named owner of a named gym, ideally a full conversation rather than a short clip. Then look the gym up yourself.
Should a gym marketing agency guarantee leads or new students?
No. Results depend on your market, your gym, and how you follow up. An honest agency explains what it builds and shows what it has done, without promising a specific number.
Is it a red flag if I can't find the agency owner online?
It isn't proof of anything bad, but it means you can't check their track record or hold anyone accountable. For something tied to your gym's reputation, being able to find the owner matters.
Who runs Grapple Growth?
Tanner Sullivant, a BJJ brown belt and military veteran who started Grapple Growth in 2023 to build websites, local SEO, and lead automations exclusively for BJJ and MMA gyms. You can find him on Instagram at @tsullybjj and on YouTube.
