Rex Tech Ventures

Software built inside real estate.

Rex operates 20,000+ apartment homes. We build the software our own teams needed to run them, then sell it to the industry. Eight products, all built from scratch, all generating revenue.

Used on properties we operate before it is sold to anyone

Global real estate market
The thesis

Real estate is a $280T industry. Its software was built to keep newcomers out.

Three times the size of the global stock markets, and most of it still runs on spreadsheets, phone calls, and tools from another decade.

01

Archaic tech

Work orders on whiteboards. Invoices re-keyed by hand. Pay stubs checked by eye. The biggest asset class in the world runs on the thinnest software.

02

Walled gardens

The incumbent systems own the data and decide who gets in. A new product has to win access before it can help anyone.

03

Outsiders underestimate it

Startups without operating experience miss how a property actually runs. Rex builds on 20,000+ units we operate, so every product gets used by a real team before it gets sold.

The portfolio

Eight products. One operating stack.

Each one started as a problem on a Rex property. Pick a product to see what it does and where it runs.

How we build

Run it on our own units first.

Every Rex product follows the same path. That is why the first customer is never a guess.

1

Operate

A problem shows up on a Rex property: a 2 AM call nobody answers, an invoice that takes three people to code.

2

Build

A dedicated team builds the fix and ships it to our own maintenance, leasing, and AP teams, who use it every day.

3

Sell

Once it works across the portfolio, it gets its own brand, site, and team, and sells to the rest of the industry.

Two ways in

One portfolio. Two perspectives.

For operators

Fix one problem at a time.

Every product sells on its own, with its own team and site. Start with the one that hurts most and add the rest when you are ready.

For investors

Back a portfolio built from inside the industry.

Rex funds and builds each product in-house, on properties it operates. Eight products, all generating revenue, with the distribution of a 20,000-unit owner behind them.
