About
Built in Texas, made for businesses that want to grow.
H1 Collaborative is a Texas-based marketing agency built to help businesses grow with clarity, speed, and accountability. We work with owners and operators across Texas and nationwide who are ready to turn attention into revenue.
We are here for the long haul. Our focus is on building systems, content, and campaigns that keep producing value long after the launch. No vanity metrics, no disconnected tactics, just work that moves the business forward.
Established in 2024, we have already partnered with a wide range of businesses across industries, from local service companies to brands scaling nationwide. Every engagement is built around the same question: what will actually make this business more valuable?
Our home base is El Paso. We work in person across El Paso, Las Cruces and southern New Mexico, treat Dallas-Fort Worth as our second focus market, and work remotely with businesses across Texas and beyond. See where we work.

Founder
Zechariah (Zack) Harrelson
Zack Harrelson was born and raised in El Paso, Texas. He founded H1 Collaborative in 2024 to build the kind of marketing and AI systems he wanted local businesses to have: connected, measurable and built to grow revenue, not just followers.
He loves AI, social media marketing and ads, and he loves the work itself: sitting down with an owner, finding where the growth is and building the system that captures it. He leads H1's strategy and client work.
His goal is simple to say and hard to do: be the best in the world at what he does, and build and lead a team that is the best in every field it takes on, starting with the businesses in his hometown.
