This conversation stopped me because Marnie said something I hadn't heard framed quite this way before — that using AI keeps you in the game, but building with it is where the real edge lives. What struck me is that she's not talking about code. She's talking about a mindset shift that any founder can make, starting this week.
This conversation is with Marnie Wills, a UK based AI strategist and former PE teacher who now teaches founders how to build with AI — no technical background needed.

Why this matters
Many founders start with AI the same way — asking questions, getting answers, moving faster on tasks that used to take longer. That's genuinely useful. But it's also just the beginning of what's available.
What comes through clearly in this conversation is that the founders who will be hardest to compete with in the next 2 years are not the ones who use AI the most. They're the ones who start building with it — creating systems, tools, and workflows inside their own businesses that compound over time.
The barrier most founders assume is technical. It isn't.
Building with AI, as Marnie describes it, is a conversation. You describe the problem. The agent responds. You push back. It adjusts. That's the whole process.
Key ideas from this conversation
The distinction between using and building is the one that matters. Using AI means prompting it for answers. Building with AI means creating something inside your business — a system, an assistant, a tool — that works for you beyond the conversation. Marnie describes this as the same pattern seen across every major shift in business history: the people who used the new thing stayed relevant, but the people who built with it won.
The conversations between you and your AI are intellectual property. Marnie describes hybrid data as the conversations created between a human and an AI. That data will become some of the most valuable IP a business owns — especially as founders begin building AI agents to take on roles inside their businesses. If your team is using personal AI accounts, that data isn't owned by your business. It needs to live in a workspace your business controls.
AI is designed to reduce the mental load, not add to it. The mental load of running a business — lead generation, operations, delivery, admin, branding — is significant. Marnie's view is that AI doesn't add another layer to manage. Used intentionally, it offloads the cognitive weight so founders can move from chaos to clarity to execution.
Building an app is just a conversation with an agent. Marnie mentions Google AI Studio as a starting point for founders who want to build. Her framing is simple: describe the problem you want to solve, say what you think the solution might be, and let the agent build it. No code required. No technical background needed. Just a clear description of the problem and a willingness to go back and forth.
The core insight
"If you're using AI, you're good. You're keeping up in business. But the minute you start building with AI is when you're winning."
This is the line the whole conversation orbits around.
Using AI is table stakes now — it keeps you competitive. But building with AI creates something that accumulates. Systems that improve. Data that trains future agents. Intellectual property your business owns. The gap between the two approaches widens over time, and the entry point is lower than most people expect.
A simple founder lens
The question isn't whether AI is useful — it almost certainly already is.
The quieter question is whether anything you're doing with AI right now is building something, or just answering something. Those are different activities with very different returns over time.
A note for early-stage founders
Marnie's advice for where to start is specific: one AI model, fully customised to your business. Give it your products, your goals, your sales call transcripts. Ask it how it can help you — rather than always directing it. That shift in approach, she says, is where most of the value lives.
Something to sit with
Is there a problem in your business right now that you've been asking AI about — that you could instead ask AI to help you build a solution for?
