Jack Hayes


Jack founded The Vector Group in the late ‘60s as a business consultancy to mid-market logistics companies who were interested in growing their top-line performance. He was a pioneer in the field of management consulting and over time his practice morphed into a consulting model he called Build:Sell:Play. Using that model, he assisted small business owners to achieve their dream of increasing the value of their businesses and selling at multiples well-above industry averages.

His son Jeff joined the firm in 2003. In late 2005, Jeff approached Jack with an idea: to shift The Vector Group’s biz dev focus on to business owners who were committed to social and environmental entrepreneurship – he wanted to go after “green businesses” as they were becoming known.  Jack’s response was “over my dead body”. It was a defining moment for the firm.

But times change - and people do too - and Jack has since become a big fan of The Vector Group’s groundbreaking eco-business tools, FootPrinter™ and CONDUCTOR™ . When he’s not serving on boards you can find Jack on the tennis court playing men’s doubles, or traveling with his wife Charlotte.
