We built the bridge between great coaches and the people who need them.

DoorGuard is a mobile training network, with credentialed coaches, real reviews, secure payment, and zero friction between a client wanting to train and a coach ready to teach.

01. Origin

Why DoorGuard exists

The fitness industry has a broken discovery problem. Great coaches, the ones who actually get results, are teaching privates out of garages and gyms with no way to reach clients who need them.

And clients? They're stuck scrolling Yelp reviews and hoping for the best.

DoorGuard fixes both sides of that equation.

02. Founder

Meet the founder.

Kade Anastasios Tsitos

I'm a world champion with a degree in Exercise Science and over ten years of coaching experience, and I still couldn't find clients.

For five years I did everything I could. Cold outreach, word of mouth, posting online. I hit a drought. The problem was never my skills. It was the connections.

There are countless great coaches out there struggling to make a living. And on the other side, people who want to train but don't have time to drive to a gym, don't want to leave their house, or just want to learn in their own space on their own schedule.

I built DoorGuard because nobody, whether you teach BJJ, self-defense, or personal training, should have to struggle to find great clients. And nobody looking to get better should have to struggle to find a great coach. Not anymore.
