Allegro was founded in 1984 by Eldon Klaassen.^[1][2][3] The company was the first to develop an enterprise software platform designed specifically to manage trading, risk management, and logistics associated with physical commodities.^[1][4]

In June 2013, Eldon Klaassen, founder and former CEO of Allegro, sued the company and directors Mick Pehl, Bob Forlenza, Patrich Simpkins, and Ray Hood for fiduciary breach. On October 16, 2013, Vice Chancellor J. Travis Laster handed down a 56-page memorandum opinion that said the claims asserted by Eldon Klaassen were barred because of his delay in bringing his suit.^[7]

The company’s primary product is Allegro Horizon, an enterprise-level risk management architecture.^[8] The software is used by traders, risk managers, and decision-makers across the globe, including energy industry companies.^[1][9]
