Anubis Consulting Group (ACG) is a business consulting firm built specifically for gym owners, martial arts academies, and service-based businesses across the United States. We exist to solve the real problems that quietly drain revenue, kill growth, and burn out owners, overpaying on payment processing, using the wrong software, and running marketing that simply doesn't convert.
ACG was founded by Gannon Lang, a black belt under Keenan Cornelius and Andris Brunovskis and the owner of Nexus American Jiu-Jitsu, a thriving academy he grew to over 230 members. Having built his own gym from the ground up, Gannon understands exactly what it takes to scale, and what most consulting "gurus" get completely wrong. He's not a marketer pretending to understand your business. He's an operator who has lived it.
Our core services cover three pillars: payment processing optimization (we help gyms stop losing thousands of dollars a year to unnecessary fees), software stack consulting (finding the right tools for scheduling, billing, and member management), and targeted digital marketing, including high-converting Meta ad campaigns, professional website design, and landing pages built to fill mats.
We work with Jiu Jitsu academies, MMA gyms, home service companies, restaurants, law firms, and more. Every engagement is hands-on, direct, and results-focused. No fluff. No cookie-cutter strategies. Just real business advice from someone who has actually built something.
