HSI

Heidrick & Struggles International Inc

A leader in the business of finding and hiring top executives, this Chicago firm recruits chief executives, board members, and other senior leaders for companies around the world, and also advises organizations on leadership and succession planning. It was founded in 1953 by Gardner Heidrick and John Struggles, who gave the firm their two names. Insiders sometimes lump it into the "SHREK" club of five big executive-search firms — and its H is the second letter.
