# Community Sync - who we are

*About CommunitySync*

# The platform we built for ourselves first.

CommunitySync is operated by Trusun Media, and it runs the real estate businesses of the people who built it.

## Born in real estate community ecosystem

CommunitySync started as **KW Rental Investments** - a working platform for Keller Williams agents, with real listings, real leads and a real education library. Everything on it had to survive contact with agents doing their jobs.

What proved out there became CommunitySync: the same system, made multi-tenant, so any organisation can run its own branded portal, public website, agent directory and content library under its own name and domain.

## The people who built it

CommunitySync was started by two people — one from the operating side of real estate, one from the engineering side. It is what happened when those two problems met.

## Jason Ross

Jason has spent three decades building companies across real estate, sports and entertainment, media and technology. He is President of Next Move, overseeing 40+ nationwide expansion teams, and Co-Director of Keller Williams Sports and Entertainment, where he helped create the first Sports and Entertainment community inside Keller Williams. He founded TSM Studio, a recording and marketing studio with a twenty-year legacy serving athletes, entertainers and corporate clients, and sits on two advisory boards at Full Sail University.

CommunitySync came out of that operating experience: the system he wanted for his own agents, then offered to every organisation with the same problem.

*CTO*

## Marcin Stempniewicz

Marcin is the architect of the platform. He designed CommunitySync as multi-tenant from the ground up: every community gets its own brand, its own domain, its own feature set and its own member portal, all served from one codebase.

Before this he co-founded **Ar-range**, a visual-commerce platform for furniture brands that renders millions of product images from a single 3D source. The same discipline runs through everything here — pipelines that produce the same output on every run, and checks that fail the build when they do not.

His design rule is short: the agent’s job comes first, the system’s cleverness last.

## The company

CommunitySync is operated by **Trusun Media**, a US company based in Longwood, Florida.

How we handle your community’s data - where it lives, who can see it, and what our AI features touch - is written out in plain language on the [Trust & Security](/trust) page, and kept current.
