Our Story

Tangilla is the story of three friends who decided to spend a working week in the beautiful Kangaroo Valley in New South Wales, Australia. Apart from giving Jeff the opportunity to take some pretty pictures (see below), the main purpose was to take a hard look at the North American Real Estate industry to identify an opportunity to focus our complimentary experience on solving a meaningful problem.


Was there a meaningful problem we could solve? The answer was a definitive yes. We had all worked closely with REALTOR® Association staff over the course of our years launching various real estate technologies. This included our time together at RealSatisfied. As a result, we had developed strong relationships with a number of Association Executives. As friends, they would often share pains unrelated to the software we were providing.

The stories we heard consistently centered around the inefficiency of the platforms available for managing communications with Association members. The plots became familiar. The software was hard to learn, hard to use, and it was hard to get meaningful information in and out of the platforms. To make matters worse, tales of attempting to switch to other known platforms were told with regret. They had nowhere to turn.

From our temporary home on the Kangaroo River, we called around to a few of our Association friends. It quickly became crystal clear – REALTOR® Associations needed a fresh approach to the software used to manage their member relationships. Existing software offerings were outdated and over-complicated. Our solution would need to be a true SaaS platform built from the ground up on the latest technologies, with a fresh design that was both flexible and easy to learn.

Tangilla is that platform. It is the result of listening to the needs and desires expressed by Association Executives and Staff just like you. We know we have solved a real problem. And we're proud of the solution we've built for specifically and exclusively for REALTOR® Associations.

We think you will be too.
