How the powered-by loop works

Every time a user publishes something made with your product, other people see it. A badge on that output turns each viewer into a potential user:

  1. A user creates something: a form, a booking page, a website, an email.
  2. They send it to their own audience: customers, prospects, subscribers.
  3. Viewers use it, see the badge, and some click.
  4. A few of them sign up, create their own, and the loop starts again.

The viewer isn't seeing an ad. They are using a working example of your product, made by someone they already trust, at the exact moment they see what it does. That is why this loop can be so cheap.

The original is Hotmail. Investor Tim Draper pushed the founders to add a line to the bottom of every email; they agreed, minus his proposed “P.S. I love you” opening, and growth took off within hours. Every email sent was an invitation to get a free account. Within 18 months Hotmail had some 12 million users.

The strength of the loop is roughly viewers per user × click rate × sign-up rate. Most of the leverage is in the first number, which is why the products that win with badges are the ones whose output gets seen by a lot of people: emails, forms, booking pages and public websites.

Badge vs. branding removal: the pricing lever

Almost every company with a badge lets customers pay to remove it. That turns one feature into two jobs: free users spread the product, and brand-conscious users upgrade.

  • Calendly lists “Remove Calendly branding” as a paid personalization on its pricing page.
  • Typeform removes the Typeform footer from forms on its Plus plan.
  • Webflow removes the “Made in Webflow” badge from the bottom-right corner of published sites on paid site plans.
  • Tally puts branding removal in Pro ($24 a month); Softr in Pro ($99 a month).
  • Lovable made hiding the “Edit with Lovable” badge on published sites a paid feature, and the badge now comes back on the next publish if a workspace downgrades.

There is a smarter version: make the user want to keep the badge. Mailchimp requires a referral badge on free accounts' emails, and paid users can keep it to earn referral credits. Elena Verna pointed out that Superhuman turned its “powered by” footer into a referral link, so the user benefits when someone signs up through it. A badge that only helps you gets removed; a badge that pays the user stays.

    Every Hotmail email ended with a line inviting the recipient to get a free account. Investor Steve Jurvetson said Hotmail reached some 12 million users within 18 months.

  • CalendlyBranding on booking pages

    Free booking pages carry Calendly branding, so every invitee sees the product working; removing it is a paid personalization.

  • SuperhumanFooter as referral link

    Superhuman made its “powered by” footer a referral link, so the user gets a benefit when someone signs up through it and has a reason to keep it on.
