When I was at Blinkist, one of the things that I was really proud of is establishing paid content as one of the main drivers — Outbrain and Taboola. That took me and my team I think nine months. It's a long time, it's like nine months of suffering and really bad performance and people saying are you sure you know what you're doing, but it eventually paid off.
Budget any new paid channel for 9 months of bad numbers before judging it
Blinkist's now-flagship paid content channel took nine months of poor performance and internal skepticism before becoming a top driver. New channels need a multi-quarter runway and explicit air cover, not a 30-day kill switch. Protect long-horizon bets from short-term ROAS judgments.
Every click you're losing 10% of your users. I have to install Netflix's app store, get a big scary sheet — I'm a normie, I don't know what this is but it looks scary. Then navigate inside and click again, another big scary sheet. By the time you get to the end of this chain — 30% comes at you real fast when you compound a couple gates.
Two scare sheets + every click loses 10% = compounding conversion loss
Apple inserts two Apple-controlled scare sheets in the sideloading flow: one to install the marketplace, one for each app inside it. Each is a friction point Apple controls. The compounding effect roughly recreates Apple's 30% cut as conversion loss instead of fee — the friction IS the moat.
There's a play for whatever you're stuck on.
