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

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.

02. What we do

A two-sided marketplace, on your terms.

04. What makes us different

The four things we won't compromise on.

• Your preference, maximum convenience.

  Train at home, in your garage, at the park, at work, etc. The coach adapts to you not the other way around.

• Reviews you can actually trust.

  Every rating comes from a verified account that booked and paid through DoorGuard. No anonymous stars, no fake five-star padding. What you see is what that coach actually did.

• Money moves clean.

  No cash, no Venmo, no awkward payment conversations. Book and pay in the app. Coaches get paid directly to their bank account easy.

• Built by someone who lived it.

  DoorGuard wasn’t built by a tech company that saw a gap in a spreadsheet. It was built by a World Champion athlete who spent years grinding to find clients despite having the credentials to back it up. That context is in every decision we made.
