Nokia announced in late August that Tero Ojanperä, the executive VP and a member of the the company's leadership team, was leaving the company after 21 years to become managing partner of a new investment fund Vision+.

During his time at the company, Ojanperä served in various roles, including chief technology officer, chief strategy officer, head of research and executive VP of services. Ojanperä's contract with Nokia ended Friday (Sept. 30). Here is his farewell letter to colleagues:

"Today is my last day at Nokia. Since the day, 21 years ago, I joined Nokia I have always enjoyed doing something new. It has been a great adventure with many memorable moments. I have had the privilege to serve in so many different roles as Head of Research, as CTO and Chief Strategy Officer, as Head of Entertainment & Communities and Head of Services always working on cutting edge technologies.

So after many exciting years in Nokia I have decided to create something new on my own. A new product investment fund Vision+ ( is focusing on commercialization of great products especially in Converging Gaming, Entertainment and Education, Preventive Health and Wellness and Clean Water and Energy. Vision+ finances products and earns its return based on the income generated through the commercialization of the product. It is a well-known model from video games industry but this goes way beyond that. Nokia is also participating as an investor so my relationship with Nokia continues. However, Vision+ is independently run and will invest into applications for all major technology platforms."
