I just read an article in the Wall Street Journal about the rise in acceptance of business start-ups by large corporations. According to the article, large corporations such as Vanguard Health Systems are broadening their base of technology companies beyond the Microsofts, Ciscos, and Oracles of the world (i.e., other large corporations). More are relying on the quickness, nimbleness, and flexibility of smaller companies.
The article states that CIOs, the perennial technology decision makers, are the ones leading the charge. This bodes extremely well for tech and related startups. If you have a tech company and want to make inroads into a large corporation, pursue the CIO. Stay away from the IT Director and others. Go straight for the top. Even go for the CFO. Think big and it will pay off.
