The most expensive data in construction is the kind that never gets written down. It lives in the foreman's notebook, on a grease-stained timecard, or in the gap between what a crew was supposed to do and what they actually did.
For ten years, Rhumbix quietly built a business on capturing that data where it lives, on the jobsite. Its platform consolidated timekeeping, production tracking, and billing for trade contractors [Rhumbix].
In 2024, Autodesk acquired the company, folding its field-first workforce management system into the software giant's construction ecosystem [Autodesk Construction Blog, 2024]. The bet is that real-time labor and equipment data can finally plug into project forecasting and controls.
The Wedge Was the Timecard
Co-founders Zach Scheel, a Professional Engineer and U.S. Navy veteran, and Drew DeWalt, a Stanford GSB alum, started the company in 2014 following Scheel's experience as a project controls engineer in the Atacama Desert copper mines [The Org] [LinkedIn].
Their initial idea involved IoT hardware, but they pivoted to a mobile-first software wedge: accurate, digital timekeeping for field crews [LinkedIn]. By giving workers a simple tool to log hours and tasks, they captured the foundational data layer. This data flowed into production tracking, time-and-materials billing, and compliance reporting [Rhumbix].
Why Autodesk Wrote the Check
For Autodesk, the acquisition is a data play. Autodesk's tools help plan and model construction, but the link to real-time field execution has often been a manual, lagging data entry process.
Rhumbix closes that loop. The platform's reported customers include major general contractors like Turner Construction, Suffolk Construction, and DPR Construction [Construction Dive]. By integrating Rhumbix, Autodesk can now feed live labor costs, equipment usage, and production rates directly into its project controls and forecasting tools.
The Decade-Long Build
Rhumbix raised approximately $53 million across seven funding rounds from investors like Greylock Partners, Blackhorn Ventures, and Autodesk's own Forge Fund [Tracxn] [GlobeNewswire, 2018].

The Integration Challenge
The value of the Rhumbix acquisition hinges on smooth integration and adoption.
- The platform tangle. Rhumbix must convince its existing contractor base that becoming an Autodesk module is a feature, not a distraction from its 'worker-first' mission [Rhumbix].
- The data gravity well. Success requires building bidirectional data pipelines that are useful to both the field crew and the project manager in the trailer.
- The incumbent alternative. Rhumbix must beat the inertia of the status quo: paper timecards, standalone spreadsheets, and legacy field data systems.
If a mid-sized trade contractor has 500 field workers averaging $40 per hour, a 5% reduction in unproductive time or billing errors represents about $2 million in annualized labor cost clarity. Capturing that value consistently is what Autodesk paid for. Now, as part of Autodesk, Rhumbix must prove that data can reliably beat the spreadsheet.
