The platform we built for ourselves first.
Born in real estate community ecosystem
CommunitySync began as KW Rental Investments, a working platform built for Keller Williams agents, with real listings, real leads, and a real education library. Nothing on it was theoretical. Every feature had to survive contact with agents actually doing their jobs.
What proved out there became CommunitySync: the same system, now made multi-tenant, so any organization can run its own branded portal, public website, agent directory, and content library, all under its own name and domain.
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 Co-Founder and President of Next Move, overseeing 40+ nationwide expansion teams, and Co- Founder and Director of Keller Williams Sports and Entertainment, where he co-created the first Sports and Entertainment community inside Keller Williams. He founded TSM Studio, a recording and marketing studio with a twenty three-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.
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](ar-range.app), 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.
