Vulcan Capital is the multi-billion dollar investment arm of Microsoft co-founder and philanthropist Paul Allen.  We are not limited by traditional deal structures, asset classes or holding periods.  Instead we take an entrepreneur-friendly approach and can invest in both private and public companies with a long term investment horizon.  We have no defined limits on investment size but generally target investments of $10 million to $100 million or more, as well as select smaller venture investments.  Vulcan Capital was formed in 2003 and is headquartered in Seattle with an additional office in Palo Alto.
