“When it comes to evaluating the potential of a venture-funded start-up, I always look to the fundamentals: core technology, executive management team and the strength of the investors,” said Johnson. “With breakthrough DWDM packet switching technology, a management team led by industry veteran Sam Mathan, and blue chip investors, Matisse more than meets my criterion of a company poised for success. I’m excited to be joining the company.”

Most recently, Johnson was chief financial officer and senior vice president of the public company @Road. He is a California Certified Public Accountant (CPA).

"Matisse is entering a new phase in its lifecycle that requires the next level of financial and operational expertise,” said Mathan. “ I've teamed with Michael while we both were at Ascend Communications and then again when he was CFO at Amber Networks. I know first hand the value he brings to a management team, and I’m exceptionally pleased to have him join Matisse.”
