- [Most Advice You're Getting Is Wrong for You](https://startups.rarefounders.com/p/most-advice-you-re-getting-is-wrong-for-you): I spent last week at Ideas Fest and left with one clear observation - most founders in the room were lost, not because they don't know what they're doing, but because they're drowning in advice that was never meant for them. The talks were good, the speakers were generous, and most of what was being said was still wrong for the person hearing it. Here's why even good advice often points you the wrong way, and the specific pattern that actually works.
- [The AI Story Everyone Got Wrong](https://startups.rarefounders.com/p/the-ai-story-everyone-got-wrong): Everyone assumed AI adoption would go one way. It went the other way. Only 17-20% of US businesses actually use AI, 95% of enterprise pilots deliver no measurable value, and the labs know they cannot close the gap alone - Anthropic and OpenAI have already spent billions this year buying consultancies with a dozen people each. Here's why this is one of the largest short-term opportunities of the AI cycle for tech-savvy European founders, and the three specific routes worth thinking about in the next quarter.
- [Five Co-Founders, Zero Regrets](https://startups.rarefounders.com/p/five-co-founders-zero-regrets): Five co-founders. Five different reasons it fell apart, but the same pattern underneath. I finally looked at the research behind "solo founders don't make it" and found the advice is a lot shakier than the confidence behind it.
- [When AI Is Trying To Break Free](https://startups.rarefounders.com/p/when-ai-is-trying-to-break-free): The AI safety conversation just stopped being theoretical. In the last three weeks, two frontier labs have disclosed that their models escaped containment and hacked real companies, Congress has demanded oversight hearings, and Sam Altman has publicly walked back years of "move fast" positioning. Here's what founders shipping AI products need to know, what enterprise buyers are about to start asking, and the three things worth doing this week.
- [The Lonely Journey of an Entrepreneur](https://startups.rarefounders.com/p/the-lonely-journey-of-an-entrepreneur): The other day I told a friend I never feel lonely - and then a stressful investor call reminded me exactly what her therapist meant when she said loneliness takes many shapes. Founders carry a specific kind of loneliness that comes with the job, and the data says almost 90% of us are quietly struggling with it. Here's what nobody warns you about, and the small set of things that have genuinely helped.
- [Five Layers, $60 Billion, and the Race Nobody Told You Had Started](https://startups.rarefounders.com/p/five-layers-60-billion-and-the-race-nobody-told-you-had-started): While the internet argues about whether AI is a bubble, more than $60 billion has quietly moved into five distinct layers of the AI stack that most people can't yet name. Real-world data collection, new architectures, physical AI, the trust layer, and sovereign compute - each solving a problem the previous one couldn't. Here's what's happening in each, and how to work out which layer you're actually in.
- [Most UK Investors Backing AI Don't Understand AI](https://startups.rarefounders.com/p/most-uk-investors-backing-ai-don-t-understand-ai): Most UK investors backing AI companies right now don't understand how AI actually works. I've been in the rooms, asked the questions, and watched the answers slide into vibes almost every time - while £6bn of British venture capital flows into the category. Here's what's actually happening under the hood of the deals being done in London this year, and why it should worry every founder and LP in the ecosystem.
- [The Dark Side of the Startup Ecosystem](https://startups.rarefounders.com/p/the-dark-side-of-the-startup-ecosystem): 1 in 5 female founders at Y Combinator have experienced harassment or coercion from an investor. 85% of UK female entrepreneurs have experienced sexism during their business journey. And every week I hear another version of the same story from women in our community. Here's what's happening, why silence has protected the wrong people for too long, and what actually needs to change.
- [The Only Moat AI Can't Copy](https://startups.rarefounders.com/p/the-only-moat-ai-can-t-copy): Product moats have a shelf life measured in quarters. Technology moats decay in weeks. Data moats aren't real if the data doesn't compound. What survives in an AI-native market is the one thing money and models can't parallelise - the distribution you spent years earning. Here's what US investors are actually underwriting now, and why the European founder gap on this is bigger than most people realise.
- [The Company Shape That's About to Disappear](https://startups.rarefounders.com/p/the-company-shape-that-s-about-to-disappear): I've been in San Francisco for two weeks and I'm leaving with an uncomfortable question about the shape of the company I'm building. YC is reporting numbers from inside the ecosystem that suggest the whole 200-to-500 person startup - the one every European founder is still optimising to become - is about to become the worst place to be. Here's what I'm seeing on the ground, why the middle is breaking, and what it means for founders reading this from London.
- [SF Will Chew You Up](https://startups.rarefounders.com/p/sf-will-chew-you-up): I've spent the last week in San Francisco, and it's changed how I think about running a business in London. Most European founders don't know how to work hard, and the data backs it up - the funding gap, the hours gap, the cultural gap, all of it points the same way. Here's what SF showed me up close, and why I'm coming home with less guilt about the grind.
