01Context
Ukuu was a startup marketplace for renting the things people own and rarely use, like a power drill, a pressure washer, or a ladder. I joined as the designer and inherited a prototype that worked but needed a lot of help. My job was to make it feel like something you’d trust with your credit card and your drill.
02The flow
Trust is the design problem, not the layout.
The real question for Ukuu wasn’t about layout. It was whether you’d hand your $200 drill to a stranger because an app told you it was fine. So the screen I cared most about was the moment the drill changes hands. Both people confirm it, with a code only the lender can show.
- Drew opens the exchangeHe taps the code prompt in his chat with Mike.
- Enters Mike's codeType T2B4 from Mike's screen, or scan the QR code.
- Both sides confirmThe deposit is held and the return time is set, in both chats at once.
Mike is standing in his driveway holding the drill. Drew is holding his phone.
03Details
Put the deposit in the price, not the fine print.
A deposit is the only insurance a renter can see. So it sits as its own line in the price breakdown, where people look, and it says when the money comes back.

Reviews on every listing and every person.
You’re not renting a drill. You’re renting Mike’s drill. So people get ratings as well as items, and the owner’s face sits right next to the Request button.
Confirm the handoff on both sides.
Ukuu can’t see the driveway. The exchange code turns the in-person moment into a record both people agreed to.
04Familiar on purpose
New category, familiar shape.
Search, results, listing, request. Ukuu follows marketplace conventions closely, so all the novelty is in the one place it’s needed. I animated the main flow in After Effects so the founders could feel it before a line of it was built.
05What happened
I delivered the full UI, the flows, and an animated prototype of the main experience, taking the product from a rough functional build to something ready to ship. The company wound down before launch.
