A "spin-in" is a form of R&D in which a company is the sole investor in a startup. It sends a team of employees off to build an experimental product and then buys that startup for a predetermined and very healthy price.
Cisco has spent on average $763 million to acquire each spin-in that these three men have founded, even though Cisco was also the sole investor in each.
