GROUND3D's Low-Cost Sensors Map the Heat on the Street

A nonprofit founded in 2025, fresh from MIT's Delta V, is betting that community-owned data can build climate resilience where city sensors don't reach.

The most important climate data is often the data you don't have. It's the heat island on a block with no weather station, the particulate plume in a neighborhood downwind from a highway, the cultural landmark quietly succumbing to flood risk. GROUND3D, a nonprofit founded this year, is betting that the people who live there should own the tools to measure it.

Founded by Zoe Voss Lee and Wil Jones, the organization describes itself as a community planning practice. Its wedge is straightforward: co-design and deploy low-cost sensor networks and mobile data collection tools with neighborhoods, then help them use the resulting 3D street-level data to advocate for themselves [GROUND3D, 2025]. The initial focus is on New York City, tackling air quality, extreme heat, and heritage preservation [GROUND3D, 2025]. It's civic tech, but with a specific, physical point of view,the data lives on the block, not in a cloud dashboard only city planners can access.

The Co-Design Wedge

The bet here isn't on novel hardware. Plenty of companies sell environmental sensors. The bet is on a different ownership and governance model. GROUND3D's stated services,product development, strategic planning, workshop facilitation,are all in service of building what it calls "community-owned spatial data infrastructure" [MIT Orbit, 2025]. The theory is that data collected and controlled locally is more likely to be trusted and acted upon. It's a response to the perennial gap between municipal sensor networks, which are sparse and politically sited, and the granular, hyperlocal environmental justice concerns of underserved communities. If you can't get the city to install a monitor, build your own and use the maps to make your case.

Founders Lee and Jones bring backgrounds in urbanism and civic engagement, with Jones having prior roles at FloodLine, the MIT Trust Center, and the City of Boston [RocketReach, 2025]. The venture is structured as a nonprofit, a logical choice for a mission-focused entity that plans to partner with community-based organizations and city agencies, but one that inherently limits traditional venture scalability. They emerged from MIT's Delta V accelerator this year, a program known for pushing early-stage teams toward product-market fit [Martin Trust Center for MIT Entrepreneurship, 2025].

An Unproven, Early-Stage Model

The ambition is clear, but the path is entirely unmapped. This is a very young organization with no disclosed funding, customers, or deployed projects cited in public sources. The model faces significant, familiar hurdles.

  • The procurement puzzle. City agencies and large nonprofits are slow, budget-constrained buyers. The sales cycle for a co-designed planning project could stretch for years, with success often hinging on grant funding that comes and goes.
  • The maintenance question. Deploying a sensor network is one thing. Keeping it calibrated, powered, and transmitting data for years, through community leadership changes, is another. The long-term technical support burden for a small nonprofit could become overwhelming.
  • The impact measurement. The ultimate metric isn't sensors deployed; it's policies changed or investments secured. Proving a direct causal line from a community data project to a tangible resilience outcome is famously difficult, which can make sustained funding a challenge.

The nonprofit's answer will likely hinge on proving that its co-design process delivers more actionable, politically potent data than a top-down alternative, making it a worthwhile partner for agencies that need buy-in from the ground up.

For a sense of scale, consider a single city block. A basic commercial air quality sensor can cost a few hundred dollars. If GROUND3D's model can equip a community group with, say, ten sensors and the mapping tools to visualize a heat gradient, the capital outlay might be around $5,000. The real cost is the time,the workshops, the facilitation, the data storytelling. That's the service being sold. The incumbent it must beat isn't another tech startup; it's the status quo of inaction. It's the city's own inertia, and the community's lack of a technically legible case. GROUND3D is betting that the cheapest way to get a speed bump, a tree canopy, or a cooling center is to first get the data that proves you need one.
