We trained in advertising and marketing. We founded and ran several restaurants and food businesses; one of them was Santo Mar, which we opened during the pandemic and which showed us from the inside how marketing turns, or doesn’t, into full tables.

Gastrup Marketing is a marketing agency for restaurants based in Colombia, founded by Julián Betancourt and Edgar Fumero, advertising and marketing professionals. They founded and ran several restaurants and food businesses, including Santo Mar (opened in 2020 and closed in 2023), which gave them an understanding of the business from the inside. Today they work with restaurants in more than 10 countries (including Colombia, Chile, the United States, Spain, Mexico, Peru, Ecuador and Argentina) and support brands on their way to franchising.
We are marketing experts who were also restaurant owners. In 2019, Edgar (branding) and Julián (digital advertising) were working together with clients from several industries. With the pandemic, in 2020, food and restaurant campaigns took off and we decided to go further: we opened Santo Mar, one of several restaurants and food businesses we founded and ran.
That step let us live the challenges of the business from the inside: peak hours, staff, costs, manuals, turnover and how marketing turns (or doesn’t) into full tables. We learned to align communication with the offer and the operation.
It wasn’t because of the business’s results. The property where we operated fell within a government public works project and we had to vacate it. We decided not to reopen at another location and to dedicate ourselves fully to what we do best: food and restaurant marketing grounded in real operations. Gastrup Marketing was born from that decision.
Today we apply those lessons with every client: strategies that respect how a restaurant works and campaigns focused on occupancy and orders.
Plans designed around a restaurant’s peak hours, staff and real costs, not just the posting calendar.
What gets promoted matches what the kitchen and the dining room can deliver, so every campaign turns into a good experience.
We point every campaign at what moves your business, not at likes, and tell you clearly what we adjust and why.
