“Teamwork makes the dream work,” but rarely admit that a single standout is often, not always, what make the whole team work. It’s just easier to downplay outliers than to acknowledge that talent is very unevenly distributed —tall poppy syndrome in action.

Just celebrated Swedish Midsummer and America’s 4th of July back-to-back, and they perfectly capture the togetherness and individualism that set these countries culturally apart. In Sweden, gatherings are all about shared experiences. You arrive on time. You sit down together.

Last point is an interesting one; once you’re ahead on PMF, your pro tier isn’t just about revenue—it’s how you lock in users and block out rivals.

Happy 4th 🇺🇸 ! After a decade in the US, I became an American last year. This country changed my life. Now I get to raise my four daughters here—a privilege I don’t take for granted. America’s ambition is unmatched. Yes, it’s easy to see the flaws—especially right now. But

"Checkout" looks deceptively easy to implement: a few address forms and the ability to accept payments. Underneath it hides effectively all business logic a company wants to implement. As such, to build Checkout, you basically need to build all of Shopify AND get merchants to.

Social commerce seems to be struggling: Meta eliminated Checkout on Instagram and Facebook three weeks ago, and now TikTok is restructuring its Shop initiative, including a reduction in workforce. It's interesting to consider why this approach hasn't been successful. I have

The problem isn’t having something on the side. It’s hiding it. When your employer thinks they have your full focus but don’t—that’s not moonlighting, it's false advertising. (3/3).

You're hired to think. It's not about deliverables or 40 hours per week: it’s about mindshare, company integrity, and the opportunity to get more than what the job demands (in exchange for the risk that you might get less). (2/3).

The “as long as he is getting his job done” shit take misunderstands what doing something fulltime in tech means. (1/3).

I am going to get canceled once this hits the socialists who will ignore the fraud part to defend having multiple jobs. It was good knowing you all. 🫡. Didn’t expect it to leave tech.

Playing in Cursor brings back a curiosity I don't remember having since early days of trying to figure out how to build websites. The "what happens if I press this button" -thing.

Last week @CanadaKaz said something I never thought I'd hear him say: "we've become too focused as a company" 🤯. Previously we put more people behind fewer bets. But AI allows smaller teams to hold larger scope and we must rethink the atomic unit of a team. He's right.

Lean Startup taught founders to prioritize shipping over holding a vision. The push against micromanagement killed strong opinions, and turned leaders into bureaucrats. What's the point of working on a team if you're not all trying to achieve the same thing?.
