Fourth Crossing Systems

Fourth Crossing Systems is a custom software and connected-systems company based in Maple Valley, Washington, serving growing organizations throughout Western Washington. Founded in 2026, we design and build software around the way each client actually operates—not around a generic template. Our work starts with discovery. We learn how information moves through the business, where handoffs slow down, which tasks are repeated manually, what teams cannot see clearly, and which existing tools need to communicate. We turn that operational picture into a focused system that makes daily work faster, clearer, and easier to manage. Our services include custom web and cloud applications, internal business systems, custom CRMs, employee and customer portals, dashboards, reporting platforms, workflow automation, API integrations, data synchronization, application modernization, and ongoing application support.
