Tech for Non-Techies — Product Thinking & Innovation for Business Leaders
Too many smart, hardworking professionals focus on creating value, but never capture it. They take on more responsibility, lead bigger projects, deliver real results — and somehow end up getting paid the same. This is one of the most popular episodes in the Tech for Non-Techies back catalogue, and the timing could not be more relevant. It is Q4. Promotion decisions are being made right now. Budgets are being signed off. Whether you are running a business, looking for your next role, or want to get paid more in the job you are already in — this episode is for you. In this episode:...

Q4 is here. This is when budgets get signed off and promotions get decided. The opportunities won't necessarily go to the smartest or most hard working people in the room. They will go to the most visible. This episode is about how to be that person — without making daily LinkedIn content, without a PR agency, and without becoming someone you are not. Listen to learn: How to stand out now that everyone can create content with AI How to be on the list of experts that AI recommends (because people aren't going to Google search to find out anymore) The one thing that...

Crypto has grown up. It's now no longer just about overnight millionaires and meme coins. It is now how the largest corporations do business. JP Morgan has processed over $5 trillion through its blockchain division, even though Jamie Dimon famously hated crypto a decade ago. Visa, Mastercard, Fidelity and BNY Mellon are all in now too. This episode is about the grown up side of crypto — where nobody goes to jail or becomes a millionaire overnight — and why it matters to you as a business leader even if you have no intention of buying a single coin. Listen to learn: Why JP...

How much does it cost to build an app? Is my agency ripping me off? How do I know if what they built is any good? Am I being too demanding — or not demanding enough? Every non-technical founder is terrified when they start working with developers. If you don't have a background in tech, you don't know what you don't know and asking AI can spin you down a rabbit hole. My guest this week has spent years on the other side of that conversation. He knows what founders get wrong, what agencies hide, and what it actually costs to build a product. Vuk Nikolic leads Hurricane Studio — a...

Contrast two AI projects. One cost $600,000 to build, $500,000 per year to maintain and was shut down as functionally unusable. The other cut energy waste, reduced equipment damage, and returned 35.8% on investment. Same tech. Different outcomes. The difference had nothing to do with the AI — and everything with how the project was set up and managed. In this episode: The New York City AI chatbot that confidently told people to break the law The Korean steel plant that used AI to solve one specific measurable problem — and returned 35.8% on its investment The five reasons AI...

Tope Awotona had no co-founder, no coding ability, and three failed startups behind him. None of that stopped him — today, Calendly is worth $3 billion, used by over 20 million people in 230+ countries, and adopted by 86% of the Fortune 500. In this episode, I break down exactly how a non-technical founder built one of the most capital-efficient startup success stories of the last decade — and what you can actually steal from his playbook. What you'll learn: How he chose the idea that finally worked, after two failures How he built a $3 billion company completely alone, with no...

A financial analyst spots something wrong with a deal. He writes up his dissent. But the AI disagreed. The investment committee spent 90 seconds discussing his objection, and went with the AI score. A year later, the analyst stopped writing dissents entirely — what’s the point? This story is from finance. But the pattern is emerging everywhere — in law firms, in startups, in any organisation where AI is now in the room when decisions get made. This episode is about what to do about it. You will hear from Rana Gujral, the author of the AI Instinct: The Future of Humans and Machine...

Slack went viral without spending on ads. Dropbox grew 3,900% without a marketing team. Every founder knows these stories. What most don't know is what was actually happening behind the scenes. This episode is about the marketing myth that is costing founders millions — and what the smartest ones actually do instead. Listen to this episode to learn: The viral growth myth — why the most famous "organic" growth stories in startup history were actually the result of deliberate marketing investment Why the average UK startup exits for around $15 million while the average US startup...

A non-technical CEO built a mobile network, then transformed a startup into an AI company. Here's exactly how he did it — and what he learned about investors. Peter Scott has done things that most people would walk away from. He was handed a business running on Power BI reports and a vision that was bigger than the technology could deliver. Two and a half years later, it's a fully AI-enabled platform. Before that, he built a mobile network from scratch — with no technical background — because the opportunity was too good to turn down. This episode is his playbook. Listen to learn: ...

Did you wake up today thinking that you really want to use a cup? No! Because you are not insane. You woke up thirsty, and then used a cup. That distinction sounds obvious. But many founders and investors ignore it completely — and build or back the wrong thing as a result. This episode is about what a product actually is, and why getting this right is the foundation of everything else. In this episode: Why a product is not an app, a site or an algorithm — and what it actually is Why the person and the problem always come before the solution How companies that stay focused on the...
info_outlineYour core business is doing well. Maybe it's doing really well. But you also know that if you don't innovate in the next 5-10 years, you'll be irrelevant.
So you want to invest in the next thing. But how much? How do you do it without either recklessly spending or being so conservative that you never actually build anything?
This is the innovator's dilemma. And it's not just a startup problem — it's a corporate problem.
David Wells was the CFO at Netflix for nearly 15 years. He joined when they were a fledgling DVD-by-mail company with 400,000 customers. He didn't solve the innovation problem with reckless spending. He solved it with financial guardrails.
Key takeaways:
- Guardrails, not gates: Netflix didn't say "spend whatever you want." They set boundaries like maintaining operating margin growth and never going into consolidated net loss. This let them innovate aggressively within discipline.
- You need three types of people: Financial modelers (business thinking), data scientists (insight), and technical teams (execution). Missing one type is why most innovation projects fail.
- The CFO's real job: Not to hold the company back, but to ensure you can survive hard times. It's constant scenario planning between growth and sustainability.
- Risk tolerance changes: Risk-taking gets harder the deeper you get into life (debt, family, obligations). There's a sweet spot for taking big bets.
- Data matters more than coding: Non-technical people should understand data fundamentals and insight, not learn to code.
