Fast Gorilla Marketing Company started from humble beginnings when Shay started the company to help her father with lead generation for a home remodeling company he invested in. She built the company to a point where she was able to get a shared office space with a real estate entrepreneur, Gil, where they joined in together in business and eventually marriage. Over the years, Gil and Shay now have four beautiful children and run successful real estate and flyer distribution companies.

“Thank you for the trust, faith, and confidence that you have placed in us and Fast Gorilla Marketing to take care of your business marketing projects.” –Shay Castilla

Our company has since evolved and grown into a Texas Corporation with regional markets serving San Antonio, Austin, Dallas, Houston and Corpus Christi. We are the flyer experts since 1994 and maintain an A+ rating with the BBB of Central Texas and our proud members of a national association of advertising distribution service companies.

We offer:

  • Design, Print and Door to Door Distribution with verifiable GPS tracking
  • Business to Business (B2B) Marketing
  • Full Color Digital Offset printing (business cards, flyers, Brochures, Tickets, etc.)
  • In-house large format printing (such as vehicle wraps, banners, and outdoor signage and self-serve printing options)
  • Indoor Digital Signage with Mobile Networking features
  • Business Lunch Programs
  • and Digital Customer Loyalty Programs

At Fast Gorilla, we know how most other flyer customers feel about their flyers and we were determined to create a reliable turn-key flyer distribution service that could be easily verifiable with our real time GPS tracking service. In the beginning Shay and Gil had no idea how they were going to make it happen but they did know they had faith and believed in Fast Gorilla Marketing and were ready to put in the hard work it would take. With that one giant leap of faith, Fast Gorilla Marketing since became the #1 Flyer Distributor in the state of Texas. We’ve been recognized for our outstanding customer service, marketing, and sales by national associations.

“We provide the highest quality print and distribution service, honestly and ethically. We know how most feel about flyer distribution and that is what drives us to do it differently.” –Gil Castilla

We’ve been able to bring our family on board with this dream. Ralph is our Chief Information Officer, our son; Elijah is in our vehicle graphics department. Our younger children, Zach and Sophia find a way to pitch in around the office and help where needed. As we’ve continued to grow, we’ve also brought on folks who grew into family. Even though our family has expanded, all the new faces we’ve brought on board over the years cherish our same values and are ready to provide the excellent customer service you deserve. We’d love the opportunity to help you experience the amazing benefits of our Lead Generation programs for your business. We’re a family-owned business so we absolutely know how important your business is to you. We’d love to be trusted with the opportunity to work with you. Give us a call or click, and we’ll help generate more leads for your business! Thanks again for choosing Fast Gorilla Marketing; we consider it a blessing to serve you!

“For business not to advertise is like winking at a girl in the dark. You know what you are doing but no one else does.” — Stewart H. Brit
