Microsoft's 2015 acquisition spree shows no sign of abating: The latest scuttlebutt is that the company has snapped up Germany's 6Wunderkinder to-do list app maker. (UPDATE 6/2/15: Microsoft has confirmed the acquisition.)
As I documented in April ("What's behind Microsoft's not-so-crazy acquisition spree?"), Microsoft was off to its fastest acquisition pace ever this year with 4 deals confirmed and 1 widely rumored to have been signed (and in fact, Microsoft recently confirmed the buyout of that 5th company, Surface pen maker N-trig).
Now come reports that Microsoft has spent $100 million to $200 million on 6Wunderkinder, which recently announced that its Wunderlist to-do list app works with the Sunrise calendar app -- an app whose developer Microsoft happened to gobble up in February. Wunderlist is a popular consumer app that also has applications at the office. (Big vendors like Microsoft tend to take their time revealing sub-$1B purchases like this.)
Microsoft's acquisitions this year, including that of Acompli, have been largely focused on personal or work productivity.
