About Justin Brewer

Justin Brewer is an American entrepreneur and merchant services professional. He is the founder and chief executive officer of Greenhub, a payment processing company based in Las Vegas, Nevada. His work focuses on helping small and mid sized businesses understand credit card processing, manage fees, and use payment systems as part of their financial planning.

Brewer was born and raised in Somers, Connecticut. He studied at Sacred Heart University in Fairfield, Connecticut, where he completed a Bachelor of Arts in Communications Technology in 2013. While at Sacred Heart, he was a four year NCAA Division I soccer player and a regular starter on the men’s team. Balancing academics and athletics shaped his views on discipline, preparation, and time management.

After university, Brewer began his career in sales and digital marketing roles working with local and regional businesses. In these positions he reviewed many merchant accounts and processing statements. He observed that many owners had limited understanding of their contracts, pricing structures, and the effect of processing fees on their margins. This experience led him to specialize in merchant services.

In 2019 Brewer founded Greenhub in Las Vegas. Through Greenhub he works with clients in retail, e commerce, and business to business sectors. His approach emphasizes clear explanation of interchange, pricing models, and contract terms, along with regular review of fees.

In 2025 Brewer was named a Vegas Inc 40 Under 40 honoree. The recognition cited his leadership, activity in the regional business community, and work in the payment processing field.
