Forum Energy Technologies, Inc.
A Houston-based maker of equipment for the oil, gas, and renewable energy industries, Forum Energy Technologies builds everything from drilling tools and subsea robots (its Perry and Sub-Atlantic remotely operated vehicles) to flow-control gear used on drilling rigs and pipelines. It took its modern shape in 2010, when five separate oilfield companies—including Forum Oilfield Technologies, Triton Group, and Subsea Services International—merged into one. Fun fact: its subsea robots come from the storied Perry Slingsby Systems line, a pioneer in underwater vehicles whose roots trace to the 1960s.
