Sebastian Delmont, a co-founder and the top programmer at StreetEasy, last month became the last of a group of seven senior executives to be replaced or leave the website since it was acquired last year by the publicly traded Zillow.

Delmont, whose title was chief technology officer, departed around the same time the company launched its second redesign since Zillow paid $50 million for the then 34-person company in August.

Former colleagues credited him with developing the architecture of the popular website, most importantly a platform that understood New York City’s high-rise apartment buildings, a challenge that befuddled other national listings firms and led to Zillow’s purchase of StreetEasy.

Since the acquisition, the entire senior staff has turned over. Robin Allstadt, former COO; Sofia Song, head of research and communications; Neeta Vallab, head of product management; John Darby, head of marketing; and Daniel Sultan, head of business development, resigned or were forced out.

In addition, Michael Smith, company co-founder and CEO, was replaced in September with Susan Daimler, the general manager of Zillow New York. “I decided to leave Zillow/StreetEasy,” Delmont told The Real Deal. “I enjoyed my time at Zillow/StreetEasy and wish them all the best.”

Correction: In an earlier version of this story, Vallab and Darby’s titles were reversed.
