Project Heirs · Atlanta
We build infrastructure for buildings, power, water, networks and compute.
One company in each domain: Build, Energy, Water, Connectivity and Compute. All five start in metro Atlanta, where 4 Seasons field crews work today and the first Current, Flow and Relay devices are in development.
- Build Crews on real streets
- Energy 500, 230 and 115 kV lines
- Water Towers and tanks
- Connectivity Towers and mesh links
- Compute Readings to Groundwork

Every count is computed from the map files this site uses, and the last one from the 4 Seasons code.

Mapped assets in a 64 km square around Atlanta. Open data misses some assets, so these are counts of what is mapped. Map data © OpenStreetMap contributors, Overture Maps · ODbL. Lines of TypeScript and Swift in the 4 Seasons repository, tests and comments included.
We wrote the software for every step of it, from the price to the crew's pay.
06 · Pay
An approved step goes into the crew's pay ledger, and each payment has a receipt with the photos behind it.
One job through the 4 Seasons software
It mounts beside the electrical panel and runs the water heater and cooling on the cheapest hours of a time-of-use rate.
04 · The bill
The house gets the same hot water and comfort, bought on cheaper hours. The numbers are illustrative.
A day of power on a time-of-use rate
It measures every gallon where the main enters the house and closes its own valve on a leak, with or without a network.
06 · Gallons lost
About 8 gallons lost, against about 1,090 if nobody notices until 7 am. The numbers are illustrative.
A pipe bursts at night
It holds fiber or cable, two cell networks, a neighborhood mesh and satellite, and it switches between them on its own.
05 · Online
The house stays online through all three failures. This is the planned behavior, shown as an illustration.
Three failures in one afternoon
Groundwork starts from the 4 Seasons software and will keep the record of each house.
04 · The record
Groundwork keeps one record per house, by domain. The events here are an illustration.
The record of one house
The utilities' networks end at the meters, and the five systems past them are the owner's.
Section · one house, five domains
Left of the dashed line is the utilities' network. Right of it is the owner's, and that is where we work.
Each one is in development and none has shipped. These are design renders, and each turns in 3D.
Current HubCurrent · Energy
The Current Hub mounts by the electrical panel and runs the water heater, cooling and EV charger on the cheapest hours of the utility's rates.
Flow NodeFlow · Water
The Flow Node sits on the main water line, measures every gallon and closes its valve when a pipe leaks.
Relay NodeRelay · Connectivity
The Relay Node holds fiber or cable, two cell networks, a neighborhood mesh and satellite in one box, and switches between them on its own.
Each one stands between us and a company that works.
Bd Build (4 Seasons) · En Energy (Current) · Wa Water (Flow) · Co Connectivity (Relay) · Cp Compute (Groundwork)
There are eleven founding roles, and most of the work is in Atlanta.
