We talked about big ideas in Lisbon. Now, let's nail the developer handoff!

Everyone promises speed, but they skip the crucial steps. Stop wasting time on "just one more revision." Get the exact handoff checklist we use to go from design file to final code – clean and fast.

Stop the back-and-forth. Get straight to code with our handoff checklist.

Your team's design files are gold, but they're useless if the handoff process is sloppy.

We don't believe in friction. That's why we use clear and dimple handoffs, just like this one. It helps you:

Check File Hygiene before you even share the link.

Make sure every Technical Spec is covered so your dev team gets it right the first time.

Cut down on frustrating back-and-forth by creating one, single source of truth.

They are first-class in terms of quality, but I have been more impressed with how well they have stuck to their deadlines and how well they have embraced any change requests which we have brought in and understood that we are working in a fairly unique environment.
