137 Founders Later: What Sonia Couto Learned About Building Companies the Hard Way

Most founder stories follow the same pattern. The origin myth. The breakthrough moment. The successful exit. Somewhere in between, there is usually a version of events that makes everything sound inevitable.

Sonia Couto got tired of that story.

“I wanted to have conversations about what happened before anyone was paying attention,” Sonia says. “The fear. The failures. The moments when you had no idea what you were doing. That is usually the most interesting part of success. Because as a founder that’s what I went through myself.”

That impulse led her to create Tenacity with Sonia C., a podcast where founders talk honestly about the decisions they made, the failures they survived, the pivots they had to accept, and the resilience that got them to wherever they are now.

Three seasons. 137 founders featured. Downloads coming in from more than 50 countries every week. The show sits in the top 2 percent of all podcasts globally with 186,000 total downloads and an average of 950 listeners per episode.

What the Numbers Actually Mean

Those numbers did not happen by accident. They happened because the podcast fills a gap. Founder content usually comes in two flavors. The inspirational version, where everything worked out and the path seemed clear. Or the trauma-dumping version, where difficulty is performative and the lesson is always “stay positive.”

Sonia wanted something different.

“I wanted to talk to people who have built, failed, lost, changed, struggled and kept going,” she says. “Not the polished version of success. The real version.”

The result is a podcast where founders talk about what they actually did when the plan fell apart. Not what they learned in hindsight. Not the motivational takeaway. What they actually did in the moment when things were falling apart.

The Question Behind Every Interview

Every conversation on Tenacity with Sonia C. comes back to the same question. What did you actually learn from the version of events no one talks about?

The answers are specific. A founder talks about the product feature they refused to kill even after the data told them to. Another talks about the investor meeting where they realized they were about to run out of money. Someone else talks about the co-founder who left and what it took to keep going alone.

These are not case studies. They are conversations. The kind of conversations founders usually have privately, late at night, when they are comparing notes on what really happened.

Why Tenacity?

Sonia chose that word deliberately. She had watched other founders get stuck because they confused persistence with progress.

“Tenacity is about being willing to adapt,” she says. “It is about carrying forward what the last experience taught you while you figure out what comes next.”

That definition runs against the common understanding of what resilience means in entrepreneurship. The common understanding says keep going, never quit, push through. Sonia’s understanding says something different. Sometimes the most tenacious move is to admit something is not working, learn from it, and change direction.

“The biggest lesson I have learned is that tenacity is not stubbornness,” Sonia says. “Sometimes the most tenacious thing you can do is admit something is not working, learn from it, and change direction.”

The Mission Behind the Numbers

Sonia is focused on growing Tenacity with Sonia C. over the next twelve months. She wants to reach more founders who are navigating the realities of building a business. The fear. The uncertainty. The failures. The moments when everything feels like it is falling apart.

She is also working to help entrepreneurs use technology and AI strategically. Bringing an idea to life. Solving a problem. Creating capacity. Finding new growth opportunities.

“Everything I am building connects to the same goal,” Sonia says. “Helping founders move forward when they do not have all the answers.”

For anyone listening to the podcast or following her work, the message is the same. Success does not require certainty. It requires the willingness to start before you feel ready, fail without quitting, and keep adapting until you find what works.

That is what 137 founders have taught her. And that is what she is trying to pass on.
