This is clearly a good prez to look at. Wo do you think is adressing these points in the space? Apigee? Webshell?
The "building bricks company" or the "API driven company"
My IT infrastructure is Amazon
My CRM is Salesforce
My Storage is Box.net etc...
Lots of players in API economy
You have API managements solution : Layer7, SOAsoftware, APIgee, Mashery, 3scale and plenty of new ones.
Then you have API distribution channels with market place and automation platforms : Mashape, Zapier, Apiary Temboo, elastic, IFTTT, Webshell
To my mind, this is all API economy which is addressing this point.
