Top executives at tech companies in Southeast Michigan are very bullish, with 99 percent of them predicting an increase in revenue this year, according to Automation Alley’s annual technology industry report released Monday morning at the Detroit Institute of Arts.

Twenty-five percent expect a revenue increase of more than 15 percent.

Executives are also planning to spend more this year. Eighty-three percent expect an increase in R&D spending and 82 percent plan to hire more employees.

The report billed itself as “Southeast Michigan vs. Silicon Valley,” and polled 75 tech executives in each region. Ken Rogers, Automation Alley’s executive director, was so buoyed by results that he wrote in his forward to the report: “Forget what you know about Silicon Valley. Forget what you think about Southeast Michigan. Let’s write a new headline for tomorrow’s paper: ‘Silicon Who? Tech Industry Booming in Southeast Michigan.’ ”

Silicon Valley execs were also optimistic about prospects this year, but not quite as much as Michigan execs.

Ninety percent of them projected revenue growth this year and 81 projected an increase in head counts.

But while only 3 percent of Southeast Michigan tech executives projected a decrease in employment, the number was 7 percent in Silicon Valley.

When asked if their region provides more networking opportunities than other metro areas, 81 percent in metro Detroit said yes, compared to 77 percent in Silicon Valley.

When asked if they agree that their area has leading academic institutions for self-advancement, 85 percent of Southeast Michigan respondents said yes, compared to 68 percent in Silicon Valley.
