Simon Jenner is the co-founder of Million Labs. He has spent the last two decades building, breaking, and rebuilding startups, from selling his first business in his mid-twenties to helping shape the early UK accelerator scene and supporting the launch of more than 1,900 startups.

What makes this conversation timely is what he is seeing now. AI has made it far easier to build. People without a technical background can now ship products that once needed a team and serious funding. That has changed who gets to start and how quickly ideas can move. It has not made startups easier.

In this episode, we get into where founders still get stuck once building is no longer the hard part, why sales and distribution decide far more than product quality, and what changes when AI lowers the cost of execution but raises the pressure everywhere else.

What we cover

1️⃣ When building stops being the bottleneck

Simon explains how AI and no-code tools have compressed the time and cost of getting something live, and what that changes for founders at the start.

2️⃣ The real pressure moves to sales and distribution

As execution gets cheaper, attention gets harder to win. This part gets into why go-to-market is still where so many startups fall apart.

3️⃣ Why narrower ideas can work now

Serving a focused market is more viable when upfront build costs are lower and founders can move faster without needing a huge team.

4️⃣ Side hustles as a better runway

A lot of strong businesses start alongside paid work. That breathing room can extend the learning window and reduce bad decisions made under pressure.

5️⃣ Launching before you feel ready

Founders lose time waiting for certainty that never comes. Simon talks about what real user feedback reveals that internal polishing never will.
