Strategy Consulting for Real Estate


Beyond Ordinary Commerce

7DS Associates


Rob Hahn and Sunny Lake Hahn met while at a real estate technology conference in 2016. It was magic from the very start, for many reasons. Only one of them was the perfect overlap between their respective industry expertise.

Rob focuses on Associations, Multiple Listing Services, and Technology and Sunny specialized in Brokerages, Brands, and Agents. They found that their individual specialties complemented each other’s perfectly, and brought a balance to the combined practice that had been previously missing. With a profound love for the real estate industry, Rob and Sunny have been challenging the status quo and empowering companies to operate beyond ordinary commerce.

Rob was born in Korea and moved to the States when he was nine. The child of Methodist ministers, he lived throughout the Northeast for most of his life. As a PK ("Preacher's Kid"), Rob moved every two years and ended up attending four elementary schools, two junior high schools, and two high schools.

Sunny was born and raised in Seattle, in the same house where her father still lives, and then moved to Bellingham for school and fell in love with the access to the outdoor activities - she is an avid runner and hiker. While Rob's idea of running involves internal combustion -- "Is the engine running?"

Nonetheless, out of such differences, a beautiful unity is born. Not only are Rob and Sunny business partners, but they were married in 2017, surprising everyone -- not the least of whom were the two of them! Rob lured Sunny away from the Pacific Northwest to Texas with promises of sunshine and a life of adventure - and he delivered on all fronts.

Client Work

Where 7DS Associates differs from most industry consultants is that we conduct conflict-checks prior to taking on any new clients. You can rest assured knowing that we will not be advising your competitors. While that may cost us business, it allows us to focus solely on what is in our client's best interest. There is no replacement for integrity.

We take confidentiality seriously. With Rob's legal and Sunny's real estate sales and brokerage background, fiduciary duty means something to us. From the initial consultation, throughout the term of our contract and beyond, we keep our client's' confidences. We won't discuss or name our clients without express written consent, or if ethics or the law requires us to.
