AddyStack

Software that moves real estate.

We build the software real estate runs on — focused, fast products for the people who move property: the agents and brokers who list it, the investors who flip it. We take the industry’s messiest workflows and turn them into tools that just work.

What we build

Five products, one stack.

Each one solves a single real problem completely, rather than a dozen halfway.

flipsterz.com

Flipsterz

Flip project management, end to end — every renovation’s budget, timeline and crew in one place, from acquisition to sale.

Wolliz

A real estate platform for buyers and the agents who work with them — matching what someone actually wants against what is actually out there.

The Funkopedia

Every figure, catalogued properly — the reference a collector checks before they buy, built on the same stack as everything else here.

Garrison Realty Group

A working brokerage led by Jennifer Garrison, twenty years in the market — and the proving ground for everything we build.

Living in Lake County

A local area guide for people deciding where to live — neighbourhoods, schools and the things a listing never tells you.

Built by people who have worked inside real estate.

Not around it. We build a small number of things exceptionally well, and we ship them.
