Yahoo has acquired the to-do list app Astrid, which will continue running as is for the next 90 days. “Over the next 90 days, Astrid will continue to work as is, and we will no longer be accepting new premium subscriptions. To make future changes as easy as possible, we’ll be in touch with users shortly to share how to download data,” Astrid said in a blog post. Astrid co-founder Jon Paris revealed that the company’s apps had been downloaded over 4 million times. He thanked the company’s investors and mentors, including Thomas Korte, AngelPad, Google Ventures and its Startup Lab, Nexus Venture Partners, TMT Investments, Jump Associates, LUXr and unnamed angel investors. The app offered a unique take on the to-do list genre by syncing up with the TaskRabbit API to allow users to outsource tasks that they didn’t want to do themselves.
