AI that ships, not AI that demos
Every founder wants AI in the product. Most AI features are demos that die in a sprint. Here's how I build the kind that survives contact with real users.
Most software gets designed for the person clicking the buttons. The person signing the cheque is watching a different scoreboard. Here's how to build for both.

You've shipped software that people liked and nobody bought. Beautiful onboarding. Smooth animations. Real users saying nice things. And the renewal never came.
I spent twenty years in sales before I wrote a line of code, so this pattern makes me flinch every time. The team optimized for the user. The buyer was watching a different scoreboard the whole time, and nobody was building for it.
The user is who touches the product. The buyer is who decides it's worth the money. In consumer apps they can be one person. In almost everything else, they split.
The engineer uses the tool. The VP approves the invoice. The support agent lives in the dashboard. The ops director signs the contract because a number on a slide moved. If you only design for the hands on the keyboard, you build something delightful that never clears procurement.
Not clicks. Not session time. They're measuring whether this line item survives the next budget review. That comes down to a short list:
Build the evidence for those three things into the product and you've armed your champion for a meeting you'll never be in.
Most products hide their own value. The work happens, the metric moves, and nobody connects the two. The buyer feels a vague "things seem fine," which is exactly the feeling that gets cut when money is tight.
So surface the outcome. A weekly "here's what changed because of us" summary does more for retention than a dozen micro-interactions. It's not a dashboard nobody opens. It's the sentence your champion pastes into a status update.
The user's job is to get work done. The buyer's job is to justify the tool that helped. Design for both jobs.
Seat-based pricing quietly punishes the buyer for rolling you out. Every new user is a new cost to defend. Pricing tied to the outcome flips it: more value means more spend, and the spend explains itself.
I'm not saying seats are always wrong. I'm saying every pricing page is a negotiation with a buyer who isn't in the room, and most of them argue the seller's case, not the buyer's.
This isn't a marketing note bolted on at the end. It changes the roadmap.
You start instrumenting for proof, not just for debugging. You build the export the finance team asked for before you build the theme picker the users asked for. You treat the admin and reporting surface as a first-class product, because that's where the buyer lives, and right now it's probably an afterthought with a table and no love.
None of this means ignoring the user. A tool the user hates dies from the bottom up. The point is that user-love is necessary and not sufficient. You need the person who pays to have a reason too.
It shows up hardest in B2B, but it's true anywhere money changes hands through a decision-maker: parents buying an education app, a team lead picking a tool, a client approving a rebuild. Wherever the payer and the user differ, this applies.
Only if you treat it as either-or. The buyer needs proof; users need the thing to be good. Proof usually comes from the product being good. Build both. Skip neither.
Then you have it easy on this axis, and you should still ask the buyer question explicitly: what would make a stranger defend this purchase to themselves in a month? That's the renewal, and it's worth designing for.
Ship for the user so they stay. Prove it for the buyer so they pay. Software that only does the first is a hobby with good reviews.
If you're building something and the "who signs off" question is fuzzy, that's usually the most valuable hour of the whole project. Tell me what you're building and we'll find it. Or read how I actually work first.

A design system isn't a Figma flex. It's how you ship faster and look like one company instead of five. Here's how I build ones that pay for themselves.

One language from the phone to the database. Here's why every project I take on is TypeScript end to end, and why I stopped apologising for it.
