The Twitter cofounder announced on Wednesday that the publishing platform will be shuttering two offices in New York and Washington D.C. as part of the down-sizing. The majority of the employees let go are in sales or other business functions, leaving the engineering and product teams largely intact.

The downsizing comes as the company looks to change its business model after it felt that it was "falling short" of its original goals.

According to Williams' original mission, Medium was supposed to be a "new model for media on the internet." Yet the startup didn't exactly pioneer a new path when in October it announced that it was going to be rolling out native ad campaigns and sponsored posts on the site.

Medium has now changed its mind about that direction and the startup says it will be looking at a new way to support the internet's writers and creators.
