During his toast at Windsor Circle’s open house, co-founder and CEO Matt Williamson had a tone of gratitude and hope for the future. After an incredible two years of fundraising and product building, in 2015, the company has converted capital into more than 75 employees and a new office, dozens of new customers and profits. 

 
And momentum is gaining. 
The Durham startup is a relatively young marketing software operation, specializing in e-commerce. The company helps more than 300 e-commerce customers deliver the right marketing messages to customers, specifically through email marketing. Its customizable and responsive templates in addition to algorithms that segment different types of purchasers help retailers keep customers buying. 
 
The December 1 open house was in celebration of Windsor Circle’s new office at 212 West Main Street in the heart of downtown Durham. Located on the fourth and fifth floors of a building American Underground is refurbishing for growing startups, the space is full of open office space, corn-hole rooms, a massive kitchen and meeting area (yet somehow, no ping pong tables). The windows look down on some of the busier and more picturesque areas of Downtown Durham. 
Both multinational companies like L’Oreal and small local businesses like monogrammed jewelry maker Moon and Lola have placed their faith in Windsor Circle, and its client list topped 300 at the beginning of December. 
 
Things at the open house seem to point towards growth and expansion. The new and young employees, renovated space and new ideas being implemented all show a company hitting a major growth stage.
