Most founders don’t fail because of a lack of passion. They fail because they don’t understand their numbers.

In this episode, I sit down with Rachel Phillips, Co-Founder and COO of Fully Accountable, to break down the financial blind spots that quietly sink startups, and the simple systems that can save them.

Rachel went from practicing law to building one of the fastest-growing outsourced accounting firms in the digital and e-commerce space. But her journey wasn’t smooth. At one point, she was running payroll with $2 in the bank account, choosing to bet on herself rather than take on the wrong clients.

This conversation is packed with the kind of clarity every founder needs, especially if numbers make you nervous.

We talk about:

• The #1 financial mistake early founders make

• Why your bank account balance is NOT an indicator of success

• When you actually need a CFO (and when you absolutely don’t)

• Cutting the bottom 20% to double your profit

• How to turn your accounting department into a profit center

• Building and scaling a remote-first culture long before it was normal

• The moment Rachel realized she had to niche down or risk losing everything

If you are scaling, pivoting, fundraising, or simply trying to understand your financial reality, this episode will give you the confidence and clarity you’ve been avoiding.

At just 20 years old, Aleksandar Svetski lost everything, $200,000 in debt, wiped out by the stock market, living on a friend’s floor, and selling door-to-door to afford a can of tuna. That rock-bottom moment didn’t break him; it built him.

In this raw and unapologetic conversation, Sonia sits down with Alex to unpack the failures, pivots, and rebuilds that shaped his unconventional path from debt to becoming a leading voice in the Bitcoin space. From early entrepreneurial mistakes to launching the world’s first Bitcoin-only savings app to stepping away when regulation and burnout crushed his joy. Alex shares the truth behind resilience that most founders rarely discuss.

In this episode, we dive into:

• Losing $200K and rebuilding from zero
• The life-changing lessons of door-to-door rejection
• Why his early startup failed and how that led to Bitcoin
• Battling regulators while trying to innovate
• Knowing when persistence becomes self-destruction
• How to avoid “founder Frankenstein” product mistakes
• What the next generation of Bitcoin adoption will really look like

If you’re a founder facing uncertainty, burnout, or the fear of letting go, this episode will challenge how you think about resilience and what it truly means to rebuild.

What makes a founder walk away from stability, an excellent salary, and a clear corporate path, just to start over from scratch?

In this episode of Tenacity with Sonia C., Marco Benitez, CEO of ROOK, shares the pivotal moment that changed the trajectory of his life. From a national Taekwondo champion in Mexico to a biomedical engineer and then climbing the ladder in big pharma, Marco had everything society tells us to want. Yet he felt deeply unfulfilled.

When his wife asked, “Why are you so sad?”, it forced him to face a truth he’d been avoiding: he was meant to build, not maintain.

Sonia and Marco unpack:

• ⚡ The internal battle between comfort and purpose
• ⚡ How he navigated a high-risk pivot from fitness wearables to healthcare & insurance
• ⚡ The real emotional cost behind raising capital (400 investor calls!)
• ⚡ Why being “in love with the problem, not the product” saved his company
• ⚡ What founders misunderstand about resilience and long-term vision
• ⚡ The future of health data, wearables, and consumer control
• ⚡ How to make the leap when fear has you frozen

This episode is a powerful reminder that tenacity isn’t loud; it’s the quiet decision to keep walking, even when the world tells you to stay where it’s safe.
