SiteWorx.
The cloud platform that reads a building’s wasted watts. Built on connected lighting, it now watches water, air, gas and energy - and quietly cuts the bill.
The cloud platform that reads a building’s wasted watts. Built on connected lighting, it now watches water, air, gas and energy - and quietly cuts the bill.
Here is a fact that should bother every plant manager: you cannot fix what you cannot see. A factory burns money on lights left on in empty rooms, on a compressor that never idles, on a steam line scheduled without regard to price. None of it shows up as a single number. It shows up, eventually, as a utility bill nobody can break apart. SiteWorx exists to break it apart.
SiteWorx is a cloud-based energy and facility management platform for industrial and commercial buildings. Its founding trick is almost embarrassingly practical - it starts with the lights. Lights are everywhere in a facility, they already have power and wiring, and if you make them smart they can double as a sensor network. So SiteWorx uses intelligent lighting controls as the entry point, then extends outward: occupancy sensors, meters, environmental readings, third-party devices stitched in through APIs and gateways. The result is one view of a building that previously spoke in a dozen unconnected dialects.
The pitch is not glamorous, and that is rather the point. There is no fusion reactor here, no hydrogen. There is a dashboard that tells you the east wing has been lit and empty for three hours, and a rule that turns it off. Multiply that across thousands of facilities and you have a climate story that works because it is boring - measurable, repeatable, and cheap enough that the savings pay for the software.
Numbers worth a footnote: the software itself predates the company that now owns it. SiteWorx launched in 2017 as a product of Digital Lumens; the funding that built the underlying technology - roughly $54 million across five rounds, including a $23M Series C in 2014 - belongs to that earlier chapter. What SiteWorx Software bought in 2023 was not a fresh idea. It was a proven one that had already survived being sold twice.
“We help your facility be safer, more efficient, and more sustainable.”— SiteWorx, company mission
SiteWorx distills its entire value proposition into an acronym. It is a small idea with a real payoff - when you name the four things you are measuring, teams stop arguing about which one to fix and start fixing all of them.
Leak detection and consumption monitoring before a drip becomes a flood.
Occupancy-based system management so you condition rooms people are actually in.
Usage monitoring and scheduling optimization tied to when it is cheapest to run.
Occupancy-driven controls and load management - the fixtures that started it all.
Uses smart sensors and cloud software to optimize lighting and cut energy use while keeping safe, comfortable light levels.
Meters and monitors equipment, utility services, sensor data and environmental conditions across a facility-wide wireless mesh.
Observes occupancy and activity throughout a facility in real time using integrated occupancy sensors.
The connected-lighting and automation layer for exploring building intelligence data and acting on it.
The apps deliberately reuse the same infrastructure. The cheapest sensor network, SiteWorx wagers, is the one you do not have to install from scratch - so the lights carry the mesh, and the mesh carries everything else. Installation follows a partner model: local ESCOs and contractors do the wiring, and SiteWorx engineers guide it remotely. It is a quiet way to scale expertise without scaling headcount.
SiteWorx is B2B software with a channel at its heart. It reaches customers through building owners and operators, ESCOs and dealers, specifiers and contractors, distributors, and lighting manufacturers - the ecosystem that already touches a facility’s electrical and mechanical guts. That respect for the installed base matters: adoption in enterprise operations is a subtraction problem, not an addition one. Nobody wants to rip out what works, so SiteWorx integrates with the third-party devices already in place and adds intelligence on top.
Good technology is stubborn. The code inside SiteWorx has passed through a startup, a German lighting giant, a private-equity firm, and finally a company that took its name - because the value was never the logo. It was the data.
A Boston startup begins building intelligent LED lighting and controls for industrial spaces.
Digital Lumens closes a $23M Series C, bringing total funding to roughly $54M.
Digital Lumens debuts SiteWorx - a cloud-based platform for lighting control and building intelligence as a service.
The German lighting giant buys Digital Lumens to strengthen its IoT and facility-management software.
Private-equity firm Skyview Capital acquires Digital Lumens and Encelium from ams Osram.
Singapore-based SiteWorx Software acquires the assets and continues developing the platform under the SiteWorx name.
Refreshed Tune, Sense and Area applications launch on a rebuilt siteworxsoftware.com.
SiteWorx began as a Digital Lumens product in 2017 - the platform predates the company that now bears its name.
The system often piggybacks on fixtures: your lights double as a wireless sensor mesh for the whole building.
The entire value proposition compresses into WAGE - Water, Air, Gas, Energy.
Roughly 42 people operate a platform used across facilities on three continents.

It’s a cloud-based energy and facility management platform that unifies smart lighting controls, sensors and metering to help industrial and commercial buildings cut energy and resource waste.
Yes. SiteWorx was originally a Digital Lumens product launched in 2017. SiteWorx Software now owns the Digital Lumens brands and continues developing the platform.
SiteWorx Tune (lighting control and energy savings), SiteWorx Sense (metering and environmental monitoring), and SiteWorx Area (real-time occupancy tracking).
Building owners and operators, ESCOs, contractors, specifiers, distributors and lighting manufacturers - across thousands of facilities worldwide.
Its US operations are in Shrewsbury, Massachusetts, with additional presence in Singapore and Dubai.
