Market Gap & Origin Story
Market Snapshot: In 2012, social media management meant expensive enterprise tools like Hootsuite ($99/month) or clunky manual posting. SMBs and freelancers were underserved, stuck between overpriced solutions and time-consuming native platform management across Facebook, Twitter, and emerging networks.
Origin Scene: Thanksgiving weekend 2012. Ervin's brother needed a free Facebook scheduler for his travel agency in Tirana. No decent options existed under $50/month. Ervin built a simple Facebook app over three days—his first taste of solving real pain. Six months later: first paying customer. The travel agency? Now one of Albania's biggest, powered by that weekend hack.

- Build affiliate program early — 50-70% first-month commissions create army of promoters spreading organically.
- Price per social account, not seats — Simple math beats complex tiers; customers pay for what they actually use.
- Launch on AppSumo when ready — Lifetime deals sacrifice margin for massive user acquisition and social proof.
- Stay lean, bootstrap hard — 19 employees at $2.4M ARR = healthy unit economics and founder control.
