Rahim Siddiq and Burhon Nassir, cofounders of Silk (Duolingo for the Central Asia diaspora), share how they built a viral app in 48 hours and crossed 150K+ views on their launch video.
In this interview we cover:
- How they validated the idea through content before writing a single line of code
- Why they launched at 60% done and had their first purchase overnight
- The "to really sell, you gotta not sell" philosophy
- How they filmed the winning video in 20 minutes and edited it inside TikTok
- Why pain points matter more than the build itself
- Testing content with trial reels and A/B hooks
Rahim and Burhon won Week 1 of the Replit Agent 4 Content Challenge.
