Companies that use Fly.io

I noticed that Fly.io attracts companies building digital infrastructure and platforms, often with AI at their core. These aren't traditional SaaS businesses. They're creating marketplaces (Pickle for fashion rental, Peek for experiences), developer tools (Spacedrive, Roomote), AI agents and automation platforms (Humanlike, Zerg AI, Luno), and specialized vertical software (Evitat for construction, autarc for heat pumps). Many are tech-enabled service businesses that need reliable, scalable infrastructure to power customer-facing applications.

These are overwhelmingly early-stage companies. Most have 2-50 employees, with funding stages clustering around pre-seed, seed, and Series A when disclosed. Many show no funding information at all, suggesting bootstrapped or very early operations. However, I spotted some outliers: mature businesses like Fletchers Solicitors (1,+ employees) and established brands like Loloi Rugs, indicating Fly.io also serves companies beyond the startup world.
