A live model the whole team can work at the same time. Move an assumption and the numbers move with you, with your partners and a team of focused agents on the same model. Every number traces to its source.
The Upside Explorer came out of our own development work, and it is the clearest example of what we do. Try it on a deal. Then, if it fits, we can go deeper on it with your team, shape it to your work, or build and operate a system to your specifications.
Industry surveys say nine in ten real estate firms are piloting AI, and one in twenty got what they hoped for; the gap is trust in the numbers, not the models. On a complex deal the value hides in the gaps: siloed teams, a pro forma only one person can really drive, and dozens of moving variables that never get tested together. The Upside Explorer makes the whole model live and shared. Change any assumption and watch the deal respond, with your partners and a team of focused agents working the same numbers beside you, every move attributed, every input sourced.
Two parts, kept apart on purpose. One underwriting model does every calculation, the same way every run. The agents only ever propose assumptions. So an agent can be wrong about a number without ever being wrong about the math, and nothing it does can quietly nudge the result.
A fixed pro forma that runs the same calculations every time, tested number for number. Same inputs in, same numbers out. No agent can reach in and change it. This is the part you hand to a lender, with no guesswork and no surprises.
A team of agents, each fluent in one part of the deal, propose moves and show their reasoning and their source. A dedicated Anchor holds the feasibility baseline and flags anything that drifts from it. The model does the math.
Eleven agents, each a distinct discipline:
Begin with an honest base case, tied to the feasibility study and calibrated to real market comps, the program, the costs, the financing.
Move the levers yourself and watch the numbers move with you. Or hand the deal to the agents and watch them find value, one sourced move at a time.
A full underwriting: sources and uses, returns, debt, and program. Behind every assumption sits its source, its confidence, and who put it there.
“An agent can be wrong about an assumption without ever being wrong about the arithmetic. That is the whole design.”
Acquisition tools lay a single AI reviewer over a deal you have already shaped. The Upside Explorer is a development tool, for finding the value that makes a ground-up project work and keep working, for everyone at the table.
A project can fail because it never pencils. It can also fail a slower way: it gets built, then delivers a place people and the surrounding community did not really need. The first is a financial-assumption problem. The second is an outcomes-assumption problem. Now City is building an engine for each.
The financial assumptions engine, and the working example you are looking at. It finds the value that makes a project pencil and hold up, with the source behind every number.
The outcomes assumptions engine, and the twin we are building next. It clarifies what a place actually needs, then aligns the upside work here with those outcomes. Read the early thinking →
Try it on a deal you know, or book a walkthrough. Then tell us what your team needs: we can go deeper with your team, build to your spec, or drive it with you.
