Pathr is building the connected intelligence layer for boating. Our marine navigation app is live on iOS and Android, helping boaters plan safer routes, navigate waterways, monitor their vessels, and make better decisions on the water. We're also developing HelmLink, our hardware platform that connects directly to a boat's NMEA 2000 network and brings real-time vessel data into Pathr. Together, the app and HelmLink create a growing marine data network. We're building toward tools for recreational boaters, commercial operators, fleets, marinas, and other businesses that need better visibility into what's happening on the water. We're a small, early-stage team solving difficult problems across navigation, geospatial data, routing, hardware, mobile software, and marine intelligence. That means people joining Pathr early have the opportunity to own meaningful parts of the product and help shape the company from the ground up. If you're excited by boats, maps, connected hardware, real-world data, or building ambitious products at the earliest stage, we'd love to hear from you.
