seats.aero

A search engine that aggregates award flight availability across multiple airline loyalty programs, helping travelers quickly find seats they can book with points and miles. Originally built as a side project by a solo developer frustrated with the tedious process of checking each airline's website individually, it grew organically into a subscription-based SaaS business. Operating as a one-person company with no outside funding, seats.aero now generates $400,000 per month in recurring revenue from premium subscribers — demonstrating that a highly focused tool solving a genuine, persistent pain point can scale remarkably well without a large team or complex go-to-market strategy.
