YouTube tactics
How founders used YouTube videos, Shorts and creator sponsorships to grow apps. 38 tactics from 21 founder interviews.
For most apps here, YouTube meant Shorts: creator videos made for TikTok or Instagram were cross-posted there as one more outlet, which added reach at little cost. Apps built with or around a creator who already had a trusting YouTube audience did well. Founders launching to their own channels mostly saw a short spike, and one B2B tool's YouTube ads did not work.
- Halo AI had creators cross-post each video to TikTok, Instagram, Facebook and YouTube Shorts with no posting cap, and reported 600M views in 60 days and $300K MRR in 45 days.Halo AI (1)Halo AI (2)
- Payout found link-in-bio calls to action failed on YouTube, so Shorts cuts are shorter and name the app in a pinned comment; one Short got 206K views, about level with TikTok, with a download spike that day.Payout (1)Payout (2)
- Waking Up launched on Sam Harris's podcast and video audience and reportedly earns over $1M a month; a Skibidi Toilet game promoted in one Short got 50M+ views and 2-3M downloads in about two weeks.Waking UpSkibidi Toilet mobile game
- Launching to a founder's own channel gave little lasting lift: Symmetry saw only a tiny spike, and Built With Science got a launch spike and then a trickle, needing Meta ads and SEO for growth.SymmetryBuilt With Science
- Built With Science tracked clicks per long-form video and found stories of users who transformed their bodies on the app brought more trials than broad educational videos that reached more people.Built With Science
- Faceless Shorts channels reached huge view counts: one did 26M views in 28 days but earned little from ads, and one founder's Minecraft Shorts sat at zero views for six months before reaching 180M.A faceless viral video channelsA Minecraft YouTube Shorts channel
Summary written 2026-09-26 from the tactics below. Figures are as founders stated them.
What worked, with the best evidence
What didn't work, or only partly
- Run 10+ faceless Shorts channels with fake texts, cartoon clips and satisfying videos26M views in 28 days on one channel; over a billion total, but low revenue
- Curiosity Quench: Post a daily talking-head video demoing your appSome blew up, but downloads were inconsistent; ~50-60 a day
- ZenMaid: Publish blog posts and YouTube videos on your customers' business problemsLots of traffic, few direct signups; builds the brand
- Symmetry: Launch to the founders' own YouTube fitness audienceOnly a tiny download spike
- Built With Science: Hype the app launch to your YouTube viewers, course members and email listA launch spike, then a steady trickle; not a growth engine on its own
- Built With Science: Film a months-long science experiment video with real people in a rented studioOne of the year's top videos; decent but not major app conversion
- attn.design: Post about your journey every day on X, LinkedIn, Reddit and YouTube at onceLittle response, especially on X; Reddit needed heavy nurturing. One $99 sale in 30 days
- StageTimer: Run YouTube video ads for a B2B toolDidn't work; founder blames the video

- Built With Science: Mention the app softly mid-video, and tell user transformation storiesStory videos bring more trials than broad educational ones; old videos give steady monthly trials
- Waking Up: Build the app around a trusted podcaster, and put his voice in the first sessionTiny download numbers earn $200K-$1M+ a month; creator-dependence makes the app harder to sell
- Sprout: Train 2-10 creators until one goes viral, then scale to hundreds200+ active creators; 100M views a month, peaking at 400M in one week
- Curiosity Quench: Schedule a week or two of videos at once to every platformDaily posting dropped from ~1 hour to 10 minutes; the tool became its own business
- Payout: Post every creator video on Instagram, TikTok, YouTube and FacebookInstagram beats TikTok; YouTube similar (206K views) with a download spike; Facebook minor
