What Our Clients Say
Founders, product leads, and teams who shipped with us
Working with Flat 18 felt like having an in-house team. They were responsive, strategic, and nailed the direction fast.
They rebuilt our web app and the product finally felt clean and reliable. The team could ship again without fear.
They took our outdated site and made the story obvious. Cleaner UX, clearer messaging, and a site we're proud to send.
They translated complex workflows into a UI our customers actually understand. That alone was worth it.
We've worked with bigger agencies that didn't deliver half as much value. Flat 18 was fast, focused, and cared about the outcome.
Ed at Flat 18 helped design and launch our first website back in 2018.
Along with the Bitcoin Design Community, we created and delivered a new brand and website design for WalletScrutiny.
Professional, responsive, and easy to work with. We saw quick wins across the site.
