People don't read product pages. They scan, hesitate, and leave.

An interactive graphic fixes that. Add hotspots to a product image, tap to see features, specs, pricing.

Simpler than a feature list. Works better too.

Clear proof that the market is ready for a truly great Quiz Maker. See you at the starting line. #BuildInPublic

@QzzrApp Exciting :)

We implemented @forgebitz's suggestion to change the "Join waitlist" button to "Buy now".
And the result were horrible! The conversion rate (previously 25%) dropped to 2,8% 📉

The next experiment will be to use "Sign up now" as the waitlist CTA. Stay tuned 📺

@_FriedrichMerz Wie wäre es lieber Herr @_FriedrichMerz, wenn Sie sich bei den Koalitionsverhandlungen nochmal an Ihre Worte vom 6. Februar 2025 erinnern. Oder muss man das als Politiker nicht? Frage für einen Freund.

@_FriedrichMerz Wie kann man sich so dermaßen von einer Minderheit vorführen lassen und alle Werte und Versprechen der CDU über Bord werfen?
