Founders who stopped guessing at marketing.

Booking.com: On-location travel ads from four app screenshots

Booking.com helps travelers find cheaper hotels and flights: search any city, sort hundreds of stays and flights by lowest price, grab late deals and flight + hotel bundles, and book in a few taps. Travel sells on TikTok through place and mood, so the ads needed to feel like a trip, not a desk.

  • 3 on-location ads from four screenshots
  • ~5 min from upload to finished ads
  • $4.30 per ad, vs. $100+ for a UGC video

Gemrush: 41,200 installs in 90 days from ads Otto made out of three screen recordings

Gemrush is a fast match-3 puzzle game built for the commute: clear a level in under two minutes, open a free daily chest, climb the weekly league. The team had a game players loved once they tried it, and no one to make the short-form video that gets people to try it.

  • 41,200 installs from Otto ads in 90 days
  • 3.1M organic views on TikTok + Reels
  • 2,140 new paying players

Threadly: 18,600 signups and 1,240 paying customers, with zero creators hired

Threadly is a fashion shopping app with an AI stylist: a For You feed scored by how well each piece matches your style, deals under $50, and complete outfits built around anything you like. Fashion sells on TikTok through creators, and Threadly didn't have any.

  • 18,600 signups in 120 days
  • 1,240 paying customers

We'd tried posting gameplay ourselves and gave up after two weeks. Otto had three ads in our queue the same afternoon, and the speedrun one became our best install source that month. — Daniel Okafor, Founder & CEO, Gemrush
I'm an engineer, not a marketer. Now I spend ten minutes on Monday approving videos and the rest of the week building the product. — Priya Raman, Co-founder & CTO, Threadly
Creators quoted us $250 a video. Otto gave us a new creator-style ad every other day for less than one of those, and the ads actually show our app. — Maya Chen, Founder & CEO, Threadly
Being able to test three hooks a week instead of guessing at one changed how we think about growth. The before/after format still outperforms everything else we run. — Leo Martins, Head of Growth, Gemrush
