Welcome to Binary to Billions, where we explore the human stories behind technology's greatest success stories. In this episode, host Rob Scott sits down with Danny Jenkins, co-founder and CEO of ThreatLocker, whose extraordinary journey from bullied school dropout to cybersecurity pioneer embodies the power of turning adversity into innovation.

Danny's story begins in Telford, where he was bullied and dropped out at age 15, teaching himself to code and writing scripts to delete his bullies' homework files. From those challenging beginnings, he built ThreatLocker into a $1.5 billion company protecting over 50,000 organizations worldwide—from small businesses to major airports like Heathrow.

What You'll Discover:

The Bootstrap Battle: How Danny maxed out $150,000 in credit cards, splitting grocery bills across three cards to feed his family while building ThreatLocker—until WannaCry proved his technology could stop ransomware cold.

The Malware Gambit: The incredible story of how Danny wrote custom malware in two hours (with a box of wine) to demonstrate to skeptical investors that traditional antivirus was useless—securing his first major funding.

Zero Trust Revolution: Why Danny's philosophy that "only trusted software runs, everything else is blocked" has gone from being dismissed as impractical to becoming the industry standard, and how it could "dismantle the economics of cybercrime."

The AI Arms Race: Danny's candid take on how artificial intelligence is creating millions of new potential cybercriminals overnight, and why traditional security approaches are failing.

Leadership Philosophy: The mindset that helped him launch companies after spinal surgeries, his instant decision-making approach, and why ThreatLocker hires based on attitude over credentials—with no degree requirements for any position.

This conversation reveals the brutal honesty behind building a unicorn company—from sleepless nights splitting grocery payments to moments of triumph when hospitals are saved from ransomware attacks. Danny shares why success means he can never quit, the weight of protecting 54,000 organizations, and his mission to change cybersecurity forever.

Perfect for entrepreneurs, cybersecurity professionals, and anyone who believes the most audacious moves are exactly what your business needs to survive and thrive.

Binary to Billions explores the human stories behind technology's greatest success stories. Hosted by Rob Scott, founder of Today Digital and several B2B tech media publications including CX Today and UC Today.

Join host Rob Scott for an inspiring conversation with Ifty Nasir, the visionary founder and CEO of Vestd who literally created an entire industry category. Born in Bradford to immigrant parents in a cramped terrace house with nine siblings, Ifty's remarkable journey took him from teenage hustler selling refurbished sewing machines to becoming one of the youngest Vice Presidents at BP, before making the bold decision to walk away from corporate success.

That leap of faith led to Vestd - the UK's first regulated digital share scheme platform and the company that essentially invented "ShareTech." Under Ifty's leadership, Vestd has revolutionised how startups think about ownership, helping thousands of founders share equity with their teams and contributing over £1 billion to the UK economy.

Discover how Ifty's early entrepreneurial idea for "computer aided real estate" - essentially Rightmove decades before it existed - planted the seeds for his mission to democratise equity sharing. Learn about his transformative experience at Stanford discovering the "ownership effect," his strategic pivot from marketplace to SaaS, and how Vestd went fully remote just weeks before COVID hit.

From Applied Financials team members paying off their mortgages through share schemes to building a global platform spanning from the UK to India, Ifty shares the real stories behind creating life-changing wealth for ordinary workers. His philosophy is simple but powerful: giving people a slice of the pie creates better businesses and transforms lives.

This episode reveals the grit, vision, and unwavering belief required to build not just a company, but an entire ecosystem that lifts everyone up. Ifty's journey from Bradford to building Britain's equity economy proves that with the right mission and relentless persistence, you really can create an industry that changes how business rewards success.

In this episode, host Rob Scott sits down with Ray Nolan, the Irish tech legend who turned college dropout into billion-pound business builder—all without venture capital. Ray's story demolishes Silicon Valley mythology with cold, hard pragmatism and customer-funded growth.

Starting as a self-taught programmer who abandoned electrical engineering, Ray stumbled from telephone billing software into the global hospitality empire that became Hostelworld. His unconventional approach? Skip the PowerPoint presentations and go straight to customers. Ray convinced hostels to invest €10,000 each for €20,000 worth of future bookings, funding development while creating passionate advocates with skin in the game.

The result? Hostelworld grew from €150,000 to serve 12 million monthly users across 170 countries, achieving a €500 million exit in 2009. But Ray didn't stop there. As chairman of Skyscanner, he guided the company from €30 million to €500 million in three years, culminating in a £1.4 billion acquisition.

Today, Ray is pioneering AI-powered customer service with eDesk, supporting $25 billion in annual e-commerce sales—with plans to quadruple that within 36 months. His platform has been integrating AI for over five years, long before the current hype cycle, enabling small businesses to expand globally without traditional multilingual support overhead.

Ray's leadership philosophy cuts through entrepreneurial fluff: create the vision, make decisions fast, stay brutally pragmatic. His preference for making wrong decisions over no decisions has driven rapid iteration and sustainable growth across multiple ventures.

What makes this conversation essential listening is Ray's refreshing honesty about building real businesses with real customers paying real money. In an era obsessed with unicorn valuations and endless funding rounds, Ray proves that customer focus, rapid execution, and relentless pragmatism create empire-scale businesses without sacrificing ownership or soul to venture capital mythology.

What does it take to transform from a young immigrant surviving on dollars a day to building one of America's most successful unified communications companies? In this powerful episode of Binary to Billions, we sit down with Tomas Gorny, founder and CEO of Nextiva, whose extraordinary journey embodies the American entrepreneurial dream.

Born in communist Poland where his village had just one telephone, Tomas dreamed of America from age seven. His father's gift of a secondhand Atari computer sparked a lifelong passion for democratizing technology. At 20, he immigrated to Los Angeles with almost no money, surviving on a few dollars a day while carpet cleaning and building one of the internet's first web hosting companies.

By 22, he was a millionaire. Then the dot-com crash wiped out everything.

Unable to pay his mortgage, Tomas started over the same day he closed his failed business. With just $6,000 from selling his remaining stock, he bought two servers and launched what became the world's second-largest web hosting company, eventually selling for $4 billion.

But Tomas wasn't done. Identifying a critical gap—companies growing disconnected from customers—he founded Nextiva in 2008. For over a decade, he chose to bootstrap rather than take venture capital, growing organically to serve 100,000+ customers before his first VC round in 2021.

His philosophy: "Build for value, not an exit."

In one of tech's boldest moves, Tomas abandoned a product generating millions to rebuild Nextiva's entire technology stack from scratch, positioning the company for the AI revolution with a unified platform that creates a single source of truth for all customer interactions.

Key insights from this episode:

• How failure became fuel for even greater success
• The strategic benefits of patient capital over quick funding
• Why the era of disconnected business applications is ending
• How emotional intelligence trumps technical skills for entrepreneurs
• The loyalty principle that creates unshakeable competitive advantages

As Tomas puts it: "VoIP is to Nextiva as books were to Amazon"—suggesting this is just the beginning of something much larger.
