01 · Five domains
Every card says what exists or is in development today and what comes later. Nothing marked later is built.
014 Seasons
Buildings, repairs, renovations, field labor, construction robotics
02Current
Microgrids, batteries, distributed generation, physical power
03Flow
Capture, purification, recycling, storage, distribution
04Relay
Mesh communications and resilient telecom for when conventional networks fail
05Groundwork
Edge computing, physical AI infrastructure, machine coordination
Drawn solid: today or in developmentDrawn dashed: later, not built

03 · The street
A 4 Seasons crew drives one road to a row of jobs, and one visit can install a Current Hub, a Flow Node and a Relay Node. Neighbors' Relay Nodes will reach each other by radio when a line goes down.

Install a Current Hub, a Flow Node and a Relay Node08:00
All three go in during one visit, with a goal of under four hours.
Water heater replacement12:15
The price is fixed and agreed before the visit.
Leak repair under a kitchen sink14:00
A Flow Node alert opened the job.
Relay Node antenna check15:30
The visit was booked from the node's signal readings.
Building positions and the road are real, from Overture Maps and OpenStreetMap (ODbL). The open data has no side streets or building outlines here. The homes with a Relay Node, the jobs and their times are an illustration.
04 · The city
This is the infrastructure those buildings depend on, as open map data records it. Every count here is computed from the map itself.

Map data © OpenStreetMap contributors, Overture Maps · ODbL
Counts of mapped assets in a 64 km by 64 km square around Atlanta, from Overture Maps and OpenStreetMap. Open data misses some assets, so the real numbers are likely higher. The outlined square is the 490 m block from the street chapter of the home page. Point at or tap a marker to identify it.
05 · What we have built
It takes a job from the quote to the crew's pay, and it is the code Groundwork starts from. Each part below names where it lives in the repository.

01 · Quote
A vision model reads the homeowner's photos or video into catalog tasks. The code prices them, sets a ceiling for what the photos cannot show, and compares every quote with what the crew found on site. An iPhone LiDAR scan with Apple RoomPlan measures a room and reprices it to a fixed price.

ScheduleCrew days in priority order
Jobs are placed in priority order on the crew and start date that finish them earliest with the least driving. Deck days avoid forecast rain, and a crew that ends a job nearby starts the next one from there.
core/scheduling.ts · core/capacity.ts
OfferA minute to accept
A visit goes to a wave of nearby, qualified pros, each with a minute to accept. The first to accept takes it under a database lock on the visit and on that crew's calendar day, so a visit never has two crews and a crew is never booked twice.
platform/offers.ts · core/matching.ts
RouteEvery order tried up to 8 stops
The planner tries every order for a day of up to 8 stops and improves longer days by swapping segments (2-opt). Drive times come from a model corrected by the crews' own past drives, by hour of the day, weekdays and weekends apart.
core/routing.ts
Steps with proofPhotos before done
Each step has a procedure card in English or Spanish with its tolerances and the photos it needs, and it cannot be marked done with fewer. Waterproofing and the final walkthrough are gates: a reviewer approves the photos before later steps can start.
core/procedures.ts · platform/qa.ts
PayPaid per checked step
An approved step goes into the crew's pay ledger. Crews can cash out checked work from the app, each payment has a receipt with the photos behind it, and the app keeps a yearly pay statement.
platform/payouts.ts · platform/pay-trail.ts
Each scheduled job's bill of materials becomes purchase order lines, one draft order per supplier, and a kit staged the working day before the job starts.
platform/purchasing.ts · platform/kits.ts
Every job is laid out as dated money in and money out over 13 weeks. A start date that would take the company below its cash floor is not sold.
core/cash.ts
Other businesses order work over REST. AI agents order it through an MCP server with the same operations: quote, commit, follow, accept or dispute.

The plan day by day, every proof photo, payments as work is proven, the crew's van on a map, and booking a repair.
apps/home
What a crew does on site is saved on the phone first and sent when there is signal, so a basement with no bars works the same.
apps/pro/src/lib/queue.ts
Crews pick English or Spanish. The app, the procedure cards and the texts follow that choice.

06 · Build
4 Seasons crews do building work, repairs and renovations in metro Atlanta. The work runs on software from the first quote to the final walkthrough, the owner gets a fixed price before work starts, and crews are paid for each verified step.
4 Seasons is the field labor for every domain. Every device the studio puts in a building will arrive through one of its visits. Construction robotics comes later and is not built.
Current Hub
Design render · in development · not yet built
07 · Energy
The Current Hub switches a home's largest loads and schedules them around the utility's time-of-use prices. It measures every circuit it controls.
Across many homes, the same equipment becomes load a utility can call on during a peak, paid on measured results.
Flow Node
Design render · in development · not yet built
08 · Water
The Flow Node measures flow, pressure and temperature where the main enters the house, and closes its own valve on a leak, with or without a network.
Flow Reserve stores drinking water for outages and boil-water notices. Both report into the same record of the house.
Relay Node
Design render · in development · not yet built
09 · Connectivity
The Relay Node tests every connection it holds and moves traffic to one that works when the main line drops. Neighbors' nodes reach each other by radio.
Relay plans to hold the phone number on its own account, which needs carrier agreements we do not have yet.
10 · Compute
Groundwork starts from the code 4 Seasons runs on today: quotes, scheduling, offers, routes, steps with photo proof, pay and supply.
Next it adds device provisioning and the record of each site. Edge computing on the devices and coordination of machines in the field come later and are not built.
11 · One foundation
Each company has its own name, product and team. Everything that is expensive to build twice is built once.
The roles are on the careers page. Founders who want to start a domain's next company, such as construction robotics, distributed generation or water purification, can apply as founder in residence.
