Start free like Duolingo, then add a monthly paywall once AI costs pile up
Free model failed: investors wanted revenue and AI costs hit hundreds of thousands
Mixedpaywallpricing
What they did
Launched as a free product inspired by Duolingo's years of free growth, aiming to collect users and monetize later. Investors wanted revenue, and AI token costs scaled to hundreds of thousands of dollars, so introduced a first paywall with a single monthly subscription.
What happened
Free phase reached ~23K MAU but did not raise money and was unsustainable on AI costs; the switch to paid started the revenue ramp.
