Microsoft Pinpoint was a search engine/searchable online directory of software and professional services based on Microsoft. this included all of Microsoft's partners at the time (with their Partner Center), and independent IT companies. Pinpoint was launched in 2008 in the USA, and by mid 2010, more than 7,000 app listings from more than 30,000 of Microsoft's partners were on the site. by the end of 2010, Microsoft had announced a plan for expanding the Pinpoint engine to larger markets/more major markets around the world. a year before, Microsoft started to roll out Pinpoint to other countries around the world. at the end of 2017, however, it was shut down and replaced by the Microsoft Partner Center.
there isn't much information on Microsoft Pinpoint right now, which is why there is not that much writing here.
