“I have brought GMT in to support
multiple startups I work with.”
“They have strong technical expertise across paid social, paid search, and affiliate marketing, and they’re fantastic partners—whether you’re setting up your first advertising tests or looking to take existing programs to the next level through optimization. What I appreciate most is how deeply they embed with your team. They truly operate like internal performance marketers, helping evaluate and scale your efforts while staying focused on overall business impact and ROI.”

“I am 100% confident GMT is the right choice for you and your company.”
“When GMT took our account on, our programs were not ROI positive and we were not sure if we would maintain paid channels. Now, these channels bring in over 60% of our inbound MQLs. I cannot recommend GMT highly enough for any team, but especially startups who have a lot of questions to answer and something to prove. They’re knowledgeable on all aspects of advertising: the platform, tracking, technical issues, audience creation, optimization, testing, all of it. They’re experts at everything!”

“They’ve been a pillar partner for us for more than two years.”
“We never actually had a week where our sales reps ran out of demos. In fact, we had to expand the team and bring on another sales rep because our main problem became calendar availability. That level of demand helped put the company in a position to be acquired. We were acquired last year, and this was really thanks to Tushar and his team.”

“The right balance of professional and genuinely caring.”
GMT supported our paid media during high-pressure, always-on campaigns.
Their reliability, responsiveness, and commitment to outcomes made them a trusted partner we could depend on.
