The story

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

In May 2015 Frank Brienzi was appointed CEO. The company acquired Singapore-based agriculture commodities solution provider JustCommodity in June 2015.

In April 2019, Allegro was acquired by ION Group.

2013 Governance Litigation

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.
