Our Story
Named after the signal
that guides ships home.
Before radio, before GPS, ships relied on semaphores to communicate. Flags, lights, clear signals across open water. We picked that name in 2002 because it felt like us. We're not the loudest company in the room, but we're the clearest. That goes for how we talk to clients, how our teams work together, and how we build software. No noise, no guesswork.
