    • CozyKin Massachusetts | High Tech | Creates the sharing economy for childcare by matching local families together and placing them with Montessori-trained nannies in in-home nanny shares..."

    "The sharing economy isn’t just for your home or your car rides anymore. The Massachusetts startup CozyKin brings the sharing economy to your child care by matching local families to nannies and then partnering with other families in need of care. “When you join a CozyKin nanny share, you get more than incredible nannies supported by leading baby Montessori experts,” the website says. “Your child experiences the joy of growing up with another child — their new best friend.”"

    "MassChallenge is a four-month startup accelerator that takes zero equity in participating startups, which have a chance to win their share of more than $1.5 million at the program’s awards gala on Nov. 2. The 2017 cohort comes from an application pool of over 1,500, which were judged by 850 serial entrepreneurs, corporate executives, investors, academics and other community members — many of whom will remain with the program as mentors, speakers and potential partners."

    "For the founders of this startup, it’s also personal: Iyer and co-founders Tatyana Gubin and Jeremy Au all grew up in separate nanny-share arrangements of their own. Iyer says his parents moved as immigrants to Huntsville, Alabama, where they connected with another family and shared childcare. “That community was such a part of my family life,” he says."

    "At the event and afterward, I talked with a few of the investors who were there, off the record, asking them which companies they liked. Here's what I gleaned ... CozyKin is like Uber for nanny shares. That's when a couple families get together to share nannies for small kids. With daycare centers costing roughly the equivalent of a mortgage on a house on the Cape, it's a sought-after arrangement."
