INTERNAL USE ONLY — T-Mobile authorized personnel only. Not for public distribution.
T-Mobile made the investments: $160M in campus infrastructure, net-zero commitments, 61 WELL-rated locations. Willow is designed to make those investments perform the way they were intended to.
We have a building management system that controls our HVAC with general occupancy norms. We're in the market for software that will coordinate settings to match the needs of the exact number of people in a specific space at any given time without wasting energy.
HVAC efficiency. Predictive maintenance. Sustainability reporting at scale. Here's what peer organizations with comparable challenges have achieved with Willow.
The difference is not a better dashboard. It is a different operating model, where the platform can take action before anyone notices a problem.
Willow Copilot connects to the entire Knowledge Graph — every asset, every fault, every energy signal, every open work order — and answers questions in natural language. At Northern Arizona University, new technicians were productive in their first week, not after months of training.
What does this look like for a campus the size of Bellevue? Here's the kind of question your team could ask and what Copilot returns.
Watch Copilot in action ↗"We can actually know when or predict when something is going to break. We can schedule that maintenance at night when it doesn't impact customers — and then, of course, that saves a lot of money."
Chris Poinsatte, CFO — Dallas Fort Worth International Airport · Read the DFW storyWillow is a Microsoft-recognized Frontier firm built natively on Azure, available through the Azure Marketplace and eligible to count toward your MACC commitment. That means faster procurement through a vendor relationship T-Mobile already trusts and native integration across the Microsoft stack your teams rely on: Azure Data Factory, Power BI, Power Automate, and Dynamics 365.
How Willow drives innovation with Azure ↗There is a category of building analytics tools that detect faults and generate reports. They are diagnostics. They tell you something is wrong. Willow is different in kind, not degree, and the scope of what you're trying to accomplish demands that distinction.
Occupancy-based HVAC control, automated CMMS work orders with fault data, digital twin functionality, conversational AI, and the ability to scale nationally — these are platform use cases. Any evaluation should be structured around that scope.
