Film a valuable card, scan it with the app in hand, then reveal its price
First one hit 184K views; became the repeatable format behind the TikTok growth

What they did
After the brand-content flops, they found a format with the app in hand and condensed it into a hook-and-demo series filmed at sports card shows and value bins: show a desirable card for 3-5 seconds with on-screen text like 'What is this MJ card worth?', scan it with the app, reveal the value. Jacob voices over it as a vlog ('I was at a card show in Orlando and I found this Michael Jordan card'), since they really use the app to find underpriced cards (e.g. bought a $500 card for $30 and flipped it). The goal is 'what's the app?' comments; the app name is rarely said and a 'link in bio' CTA seemed unnecessary. They picked this format because every element (hook text, first image, story) is controllable and testable, unlike negotiation videos. Kyle wrote a TikTok strategy doc as a checklist (hook, storytelling, 'every action, text, word should have a purpose', clear the idea as fast as possible, feel organic).
What happened
The first app-in-hand video reached 184K views; the format repeated reliably and TikTok (with a Christmas spike) plus a hard paywall took Cardstock from ~$10K to ~$30K/month.

- growth
This shipped together with other changes, so the result can't be credited to this alone.
In their words
The Superwall Podcast · Kyle Fowler - How I make $42k/mo passively with simple no-code apps (copy me)“The first one that used that was 184K, went to the card shows and condensed that into like more of a hook-demo style. That's why you can see all these like repeatable ones.”
“Yes, exactly. That's the whole premise. Like, the goal is the "What's the app?" comments. That's That's the whole goal.”
“That's why we condensed down to those like value bin ones 'cause it's so easy to control.”
“Like, every single action and text should be done for a reason if you can control it.”
