In this episode of The Founder’s Gambit, Gabriel sits down with John Martin, founder of Paid Ads, a Google Ads agency that has managed campaigns generating more than $100 million in client sales.

John’s journey started in a traditional 9-to-5 marketing job in the UK, where he first discovered the power of digital advertising. After seeing one young digital marketer outperform an entire traditional marketing team, John became obsessed with mastering Google Ads. He taught himself the platform from scratch, began freelancing on Upwork, and eventually quit his job before he was even earning half his salary, trusting he could make it work.

Over the years, John went from taking on free projects to building a global remote agency based in Thailand. He shares how he found his very first client (who’s still with him a decade later), the mistakes he made hiring too early, and why niching down to Google Ads only became their biggest competitive advantage.

In this episode, John opens up about what it really takes to scale a service business without losing your integrity. He explains why most clients come to him after a bad agency experience, the red flags business owners should look out for, and why he refuses to lock anyone into long-term contracts. John also breaks down the biggest mistakes brands make with Google Ads, how AI is reshaping the industry, and why “set and forget” is the fastest path to wasted ad spend.

You’ll also hear John’s thoughts on deep work, remote-team culture, productivity, and building systems that keep clients happy for years. From managing time zones to running an agency from Thailand, he shares the habits and mindset that keep him focused, grounded, and constantly improving.

If you’re an agency owner, freelancer, or operator looking to build a long-term business with trust, transparency, and real results, this episode is full of practical insights, honest lessons, and stories you’ll relate to instantly.
