Most people don’t bet their house on an idea.

In 2006, four founders of Marathon Consulting did exactly that. They walked away from stable, high-paying jobs, secured a line of credit, and personally guaranteed it. No salaries to start. One had a second child on the way. And just before launch, the one thing that was supposed to make the transition easier—a pipeline of clients—fell apart.

“They pulled back on their deal, and we started Marathon anyways,” said co-founder and president Tony Cortinas.

That’s the part most people don’t see when they hear “20 years in business.” They see the outcome, not the moment where it easily could’ve gone the other way. Because when that deal disappeared, Marathon wasn’t a company. It was four people, four clients, and a decision: retreat, or figure it out. They figured it out.

There’s a narrative people like to tell about entrepreneurship—that success comes from a big idea, perfect timing, or access to capital. More often, it comes down to something less comfortable: betting on yourself before there’s any real proof it will work. Marathon didn’t start with an advantage. It started in uncertainty, right before the Great Recession, in an industry shifting toward outsourcing and scale. The safer move would’ve been to stay where they were. Instead, they built something different.

They saw a gap as large consulting firms moved upmarket and offshore, and rather than follow that trend, they doubled down on something harder to scale but easier to trust: people. The mission was simple—hire great talent, deliver high-quality work, and build relationships that last. Simple doesn’t mean easy.

Over the next two decades, Marathon grew from four clients to more than 600, and from four founders to a team of 125 consultants. But what stands out isn’t the growth. It’s how they chose to grow.

“We always focused on realistic growth that also met our quality standards,” Cortinas said. “It would have been very easy to grow the company a lot faster… but that would be really shortsighted.”

That’s where most companies lose the plot. They chase speed, volume, short-term wins. Marathon didn’t. They turned down work, kept standards high, built across multiple industries to stay resilient, and invested in people for the long term instead of optimizing for quick placements. It’s not the fastest path. It’s the one that holds up.

Inside the company, that discipline shows up in ways you can’t fake. Employees don’t just pass through—they grow. An intern becomes a senior developer leading major projects. A consultant evolves into someone impacting dozens of clients across an entire portfolio. People leave, experience something different, and come back.

“There’s no better validation… than when we have somebody come back,” Cortinas said.

Clients feel it too. Not just in the work, but in the ownership—the sense that Marathon isn’t just delivering a service, but actually invested in the outcome. That kind of trust compounds, and eventually something shifts.

In the early days, Marathon had to convince people to join. It was a leap of faith—for employees, for clients, for anyone willing to take a chance on something unproven. Today, that dynamic has flipped.

“I don’t feel like we have to sell it anymore,” Cortinas said. “It’s not a leap of faith.”

That’s what happens when you stick to the bet long enough. Not blindly, not recklessly, but with conviction and discipline when it would be easier not to.

Betting on yourself isn’t the takeaway. Anyone can do that. Betting on yourself and staying the course when it would be easier to pivot, cut corners, or chase faster growth—that’s where the outcome changes.

Twenty years later, that decision has compounded into something real. The kind of company people want to work for. The kind clients return to. The kind that doesn’t just appear—it gets built.

And that’s exactly why Marathon Consulting was named to the IHR200 list—recognizing the companies shaping what’s being built across the 757.

Not because they took a risk.

Because they kept choosing it.
