EE 395 - Ireland’s Best-Kept Entrepreneurial Secret - The Untold Story of John Dennehy

The Entrepreneur Experiment

Imagine selling your startup for $18 million in less than a year—only to watch it vanish into thin air when the dot-com bubble burst.

Sounds like a wild ride? That’s just the beginning of John Dennehy’s incredible journey.

John is one of Ireland’s most successful (and underrated) serial founders. He’s the only entrepreneur I know who’s managed to sell the same company twice. Yes, twice!

In this episode, John shares how his journey went from massive wins to gut-wrenching losses—and back again. In 2024 alone, he pulled off two major sales, including the recruitment platform HireHive.

But the real magic lies in how he bought back his old company, Zartis, reinvented it, and sold it again.

John’s story has more twists and turns than a Hollywood blockbuster, and it’s packed with lessons for every entrepreneur.

This is the ultimate guide to resilience, reinvention, and embracing the unpredictable. Don’t miss it!
