Modern, all-in-one HR & payroll software for construction firms
Mason is building the AI workforce management platform for construction. We help contractors run their entire back office — time tracking, HR, payroll, compliance, and communication — without the manual work that slows teams down.

Today, managing labor in construction is fragmented across paper field notes, spreadsheets, text messages, emails, HR platforms, payroll systems, benefits websites, and accounting tools. These workflows are ripe for unification and automation through AI and modern, cloud-based systems that connect the field and back office.

Mason replaces firms' siloed tools with a single platform that connects the field to the office in real time — capturing hours, simplifying HR, running payroll, and ensuring compliance automatically. Our platform saves teams 20+ hours per week by eliminating repetitive data entry and reducing errors across HR, payroll and accounting. Workers get a modern, intuitive way to track time and manage their pay, while office teams receive clean, structured data that flows directly into payroll and job costing systems.

Construction is the least-digitized major industry in the U.S. — and we’re changing that. Mason is a NYC-based, venture-backed company on a mission to bring AI-first workflows to the field. Come build the future with us!
