Most growing software companies end up coordinating multiple vendors — one for the AI, one for infrastructure, one for integrations, one for the mobile app. Each handoff is a place the system can drift, and the coordination cost is paid by the in-house engineering lead who least has time for it.
Arc10 is one team across all of it. The senior engineer wiring the Kubernetes autoscaler is the same one writing the integration tests against Business Central, on the same Slack as the engineer shipping the AI feature into the product. The system stays coherent because the people building it stay in one room.
