Diamond Management & Technology Consultants

Mid-sized boutique strategy and technology consultancy positioned between large generalist firms and niche specialists, known for technology-enabled strategy work before acquisition by PwC.

Diamond Management & Technology Consultants was a Chicago-based management and technology consulting firm founded in 2000, specializing in strategy, technology, and operations consulting for large enterprises. With approximately 500 consultants at its peak, Diamond carved out a reputation for blending rigorous strategic thinking with deep technology implementation expertise, serving clients across financial services, healthcare, media, and retail sectors. The firm was publicly traded on NASDAQ under the ticker DTPI before its acquisition. In November 2010, PricewaterhouseCoopers (PwC) acquired Diamond for approximately $378 million, one of the more significant consulting acquisitions of that era. The deal was intended to bolster PwC's advisory capabilities in the United States, particularly in technology-enabled strategy work. Diamond initially operated as a sub-brand under the name 'PwC's Diamond Advisory Services,' preserving some brand identity during the integration period. Over time, Diamond's distinct brand and organizational identity were fully absorbed into PwC Advisory. When PwC acquired Booz & Company in 2014 and rebranded it as Strategy&, Diamond's legacy capabilities were folded into that broader advisory structure. The Diamond brand was ultimately sunset, and the firm ceased to exist as a distinct entity. Its significance lies in demonstrating the mid-2000s trend of large professional services firms acquiring boutique strategy and technology consultancies to compete with McKinsey, BCG, and Accenture.
