About G3

Owners do better when they have people.

Veteran owned and led

Our story

Built by veterans for owners who carry a lot.

Running a business can be lonely. Your team cannot hear everything. Your family hears too much. And most networking is really selling.

G3 started with a simple conviction: owners grow faster, lead better, and enjoy the ride more when they are surrounded by people who understand the weight they carry and want them to win.

We built G3 around practical coaching, candid peer forums, and shared experiences that make it easy to show up. It started in Austin, and we are building chapters across Texas.

Vision and mission

Vision

A Texas where owners grow healthy companies, lead with purpose, and have people they can count on.

Mission

Bring owners together through practical coaching, candid forums, office hours, and shared experiences so they can solve real problems and win together.

What we value

Our values

    We lead by serving. Owners, their teams, and their communities come first.

  • Candor

    We tell the truth with care. Real problems get real answers.

    We do what we said we would do, and we help each other follow through.

    Business is hard. The journey should still be good, and the people should make it better.

Our faith

G3 is Christian centered. Our commitment to service, integrity, and generosity comes from our faith, and we will not hide it. We also will never require it. Owners of every faith and no faith are welcome, respected, and fully part of G3.

Our service

G3 is veteran owned and led. Service taught us the value of a team you trust and a mission bigger than yourself. We make veteran owners a priority, and we welcome every owner who wants to build something good.
