How it started
History
Appen was founded in Sydney in 1996 by linguist Dr. Julie Vonwiller.
In 2011, Appen merged with the US-based Butler Hill Group to become Appen Butler Hill. Butler Hill had been founded in 1993 by Lisa Braden-Harder, a former IBM Research employee who worked on grammar checking technology.
In 2012, Appen acquired Wikman Remer, a California based firm that developed tools and platforms for employee engagement, online moderation and curation. The following year, Appen Butler Hill was re-branded as Appen and, on January 7, 2015, the company went public.
In October 2016, Appen acquired UK-based transcription services company Mendip Media Group (MMG). Appen also acquired Leapforce in November 2017 adding additional capabilities in search relevance, and, in 2019, Appen acquired Figure Eight. In 2021, Appen announced it has signed an agreement to acquire Quadrant, a global leader in mobile location data, point-of-interest data, and corresponding compliance services.
