Data analyst+3x marathoner. Nights and weekends I build real things with AI-a run coach off my Strava, a portfolio tracker, and more. I write what worked

I gave Claude one prompt: find a business and build it.

It killed its first two ideas on evidence. The third became a real product with a site, pricing and a launch video.

Nobody has paid for it yet. That part was always my job.

Every morning Claude reads my inbox and gives me one paragraph on what actually needs me. Not 40 unread — the 3 that matter.

The value isn't the writing. It's that it makes the call and takes the triage off my plate. Half of productivity is someone else deciding what to ignore.

Spent a week using Claude to plan a trip to China — itinerary, bookings, the lot. Got so into building the planning system that I forgot to do the business it was meant to free up time for.

The tool works. The discipline is still on me.

Everyone automating with AI learns this the hard way once: it hands you a confidently wrong answer in the exact same tone as a right one.

Build the check you'd do yourself into the thing. Flag stale inputs. Show the source. Assume it has no idea when it's wrong.

When a frontier AI model is free and everyone runs the same one, being able to "use AI" stops being a skill worth anything.

What's left that's scarce: knowing what's worth building, and for whom. The tool went to zero. The judgment didn't.

[victor luisw @victorluisw]

I'm not a founder. I have a full-time day job.

The things I build with Claude at night aren't a startup — they're me finding out what one person plus a very good tool can do now. Turns out it's more than I expected, and less automatic than the hype says.

[victor luisw @victorluisw]

Claude coaches my marathon training — reads my Strava after each run, adjusts the week.

Last month it caught what I was hiding from myself: I'd cut my easy runs to half distance two weeks running. Not fitness. A "not making time" problem. Data won't let you pretend.

[victor luisw @victorluisw]

A Chinese lab just gave away a frontier AI for free.

Everyone read it as China vs the US. I think it's about what your job is worth.

When everyone has the same tool for nothing, the only edge left is knowing what to point it at.
