More Than a Marketing Agency

“I believe that in business it doesn’t matter what you do... it matters why you do it. There’s always a greater cause in what you do than just making money. Innovation, helping people, community, company culture, and family are always going to be prior to any amount of money ever earned.
At my company, we have a very strong company culture, which we contribute to with our own ambition. For us, work is an art in which each individual get’s the chance to contribute his own mark.”

How It All Started

‘Once’ was founded by Gergo Mezes in 2021. Alongside his business partner, Matyas Laneury, ‘Once’ has been able to achieve a significant presence in the industry. Both sharing extensive background in digital marketing & sales, they’ve worked with some of the largest companies in the market. Common interests led to forming a strong partnership to become the best growth partners for up-and-coming online businesses. - efficient, predictable growth achieved through streamlined processes, transparency, and simplicity, instead of empty promises, inflexibility, or irresponsibility.
