Things I learned the expensive way, written down so you do not have to.
At Elya I built the inbound engine off 60+ long-form pieces engineered for AEO, GEO and search. Those are three jobs, not one, and treating them as one is why a page can rank and never get cited.
Bamboo Connect launched on top of an 11,700-person community that already existed. That did not solve the product. It removed the problem everyone obsesses over and exposed the one that actually mattered.
Every other product I have built fails by being unhelpful. ReliefAI can fail by saying the wrong thing to someone in real distress, and that changes what prompt engineering even is.
FutureSelf went from an idea to a stranger paying money in under three weeks, run by one person. The interesting number is not anywhere in the product. It is on the clock.
FitIL has a trainee, a trainer and a gym owner inside one product. Each of them would happily be a separate app, and keeping them a single coherent thing is the design problem, not a detail of it.
On BiroClick the analysis is free and the document is paid. That split is not generosity. It is the only honest way to sell something that might not apply to you.
Generating one good image is a solved problem. Generating the same child twelve times in a row is the entire business, and it is a different problem.
