ALE Partners have been active in the Antarctic since the late 1970s. A few have been involved with the company since the early days of ALE's precursor, Adventure Network International (ANI). In 2003, five partners came together to establish ALE and to purchase ANI. Over the following years, ALE has grown to be the premier deep-field Antarctic operator. In 2019, Mike Sharp decided to retire and his partnership share was taken over by Polar Holdings AG.
