Digital transformation is moving fast. Businesses must embrace the changes or risk getting left behind. David R. Bell, a pioneering aficionado of the digital economy and a specialist in how to integrate the digital world with the real one, is helping companies win in today’s evolving marketplace.

Bell’s international best-selling book, “Location Is (Still) Everything” (New Harvest, 2014), focuses on how we use the internet to shop and search for information. Its key thesis – that real world factors systematically drive virtual world behaviors – is reinforced though rigorous analysis and countless practical examples. Most recently, he co-authored “Pharma 3D: Rewriting the Script for Pharma Marketing in the Digital Age,” an e-book discussing how pharma companies can capitalize on patient engagement through digital marketing.

David speaks frequently and globally on digital marketing, retailing, and the future of commerce for clients including Alibaba, Google, Haier, Nike, and Ralph Lauren. He also practices what he preaches: David is an early investor in leading retailers including Bonobos (acquired by Walmart for $310m), Diapers.com (acquired by Amazon for $545m), Harry’s (valued at $750m), Jet.com(acquired by Walmart for $3.3b), and Warby Parker (valued at over $1b), among others.
