Stop designing your onboarding and signup screens from a blank canvas. The apps you compete with for attention have already done that work in public.

Large apps push far more new users through these screens than a new app ever will, and they keep changing them until the numbers move. You are not going to out-test that from a Figma file.

We call the alternative the Fast Follower Advantage: take the decision behind what already works, not the pixels, and adapt it to your own app.

Below are three current screens, captured from Mobbin in November 2026: Wealthfront shows the value, Airbnb simplifies sign-in, and Slack helps people finish. The numbers on each screen match the notes under it, followed by a paragraph each for founders, designers and builders.

A reason to sign up, before the form.

1. Start with a goal. Accounts are grouped under Save and Invest, so the first choice is about what you want, not which product you need. It feels useful, not administrative.
2. Put the payoff up front. "Cash Account with 3.95% APY" and a "0.65% boost applied" line are visible before anyone has entered a single detail.
3. Ask for details next. One tap chooses the account. The form only starts on the next screen ("Who will own the account?"), one question at a time.

For founders. Your strongest reason to sign up should be visible before the first form field. Ask yourself what your equivalent of "3.95% APY" is. If you can't name one, the onboarding isn't your problem yet.

For designers. Notice the hierarchy inside each card: a bold product name, then the incentive in a smaller line, then one sentence of explanation. The section labels do the sorting so the cards don't have to. Copy that ordering and the grouping by intent, not the purple.

For builders. The choice made here decides which path you load next, so treat it as routing. Store it the moment it's tapped, before any account exists, so analytics can show which offer pulls people in and where they drop out.
