The NOI Index

One studio. Four operating companies.

Built on shared AI infrastructure, owned end to end. Each brand owns a distinct flow in property — energy, billing, lending and robotics — and compounds across the same landlords, owners and tenants.

The Thesis · Software is eating the home

The home is becoming a piece of software. The capital, energy and labour that flow through it are being rewritten as automated, AI-native systems — and whoever owns those flows owns the next property economy.

01 / The shift

The home becomes programmable

Energy, billing, lending and maintenance are collapsing from paperwork into software. Every dollar that moves through a property is now addressable by an API.

78% of property operating cost is software-addressable
02 / The shift

Capital follows the operating system

The platform that runs the workflow captures the financing, the energy margin and the billing relationship. Ownership of the flow is ownership of the economics.

Autonomy reaches the doorstep

After the back office, the building itself. Humanoid robotics turns the home into an on-demand, serviceable surface — the final layer of the property OS.

The NOI Model

A studio, not a fund.

We don't write cheques and wait. We identify a broken financial flow in property, build the company on shared infrastructure, and compound returns across one customer base.

01

Source

Find a high-friction, high-volume flow — a bill, a loan, a meter — that property still runs on paper.

02

Build

Stand up the company on a shared AI core, design system and operating team. Weeks, not years.

03

Scale

Distribute through the landlords, HOAs and REITs already inside the portfolio. Demand is pre-aggregated.

04

Compound

Each new company cross-sells the last. One customer, many flows, rising lifetime value.

Where we're heading

From the back office to the front door.

Each year we add a layer to the property operating system. The flows came first. The home itself is next.
