Y/n - Fanfiction but you're the main character. Play fics, write your own romance novels, or discover 1M+ interactive stories.
Backed by Y Combinator

Hi, my name is Gabriel and I'm the founder of Y/n.

Y/n is an app where you can create, share, and play interactive stories. Today, 100K+ teenagers spend 3+ hours a day in the app playing characters in text stories of their own making.

A few facts about why you should join Y/n:

  • We launched 8 months ago and are already one of the top books apps in the world (reached #4 app in the App Store this month).
  • We serve ~2T tokens (~200M user messages, growing 40% MoM) per month with a team of 3.
  • We raised $14M from top VCs.
  • My co-founder Eric is a technical genius. He trained the first-ever image editing AI in the world. Before Y/n, I was the founding designer at Substack.

We're looking for a founding full-stack engineer to own most of the app surface and our personalized recommendations infrastructure. This is a role with a lot of ownership across the product!

What we expect from you:

  • You’ve built actual infrastructure (not just pushed to Vercel).
  • You’ve worked at a startup or built meaningful side projects.
  • You’re into fandom, reading, and fanfiction!
  • You're based in (or willing to relocate to) San Francisco.

Hollywood authored the dominant stories of the last century. Our mission at Y/n is to create the most entertaining stories of the next one. If creating this entertainment machine sounds interesting, do reach out!

  • Send us your Github
  • 30 min interview with Eric (CTO)
  • Live coding session with Eng team
  • 30 min call with Gabriel (CEO)
