• Our Mission

    Solve America’s childcare shortage by creating an option that lets both families and nannies thrive. At CozyKin, our goal is to help children flourish, support new parents in their return to work and to provide competitive living wages and benefits to nannies.

  • About CozyKin

    CozyKin Nanny Shares provide the personalized attention and convenience of a nanny with the structure and socialization of a daycare. It’s the best of both worlds.

  • Our Story

    Our founders, Tatyana Gubin and Jeremy Au, grew up in nanny shares, and know first hand how much nannies can transform the lives of families.

    While researching postpartum depression, our founders uncovered that a huge source of anxiety for new parents was finding quality childcare. They also found that there was a childcare shortage specifically when it came to infants. And on the care side, they knew there weren't many options apart from daycares for those who wanted a career in early education.

    What if we could help new parents find quality care that would allow them to return to work with peace of mind? What if we could help those who want a career caring for and teaching little ones find job stability? Those are the questions that drove the start of CozyKin.


  • Values Matter

    Our organization's values are fundamental to our mission. They act as a guide to inform our decisions.

    Heart for Children

    We do what's best for the children in our care. In doing so, we also do what's best for parents, nannies and our community.

    Courage in Action

    We do the hard thing. We take the hill. We own our work. We get it done.

    Accelerating Together

    Change is constant. We choose to accelerate. We champion growth, both our own and CozyKin's. We empower others to do the same.

  • Press Mentions

    "On November 2, MassChallenge held the 2017 MassChallenge Boston Awards at the Boston Convention and Exhibition Center. In addition to using their eighth-annual event as a means to celebrate the accelerator's success this year, MassChallenge Boston also handed out $1M in equity-free prizes to winners of its Top 26 startups (of 128 total). "

    "The startup accelerator’s top four winners — CozyKin, Off Grid Box, Pykus Therapeutics and Vence — each won $100,000 while 12 other startups each received $50,000. One of the $50,000 winners, Guardion, and two other startups won a share of $500,000 from CASIS-Boeing for research projects on the International Space Station. The eighteen startups were chosen out of MassChallenge’s 26 finalists, which came from a pool of 128 startups that participated in this year’s accelerator."

    MassChallenge Names Four Startups As $100K Winners

    11/2/17, Boston Business Journal

    "During the ceremony, MassChallenge awarded $100,000 prizes to each of four of the "highest-impact" companies from its 2017 class. Those companies, which lead a pack of 128 startups that entered the accelerator in June, are:

    • 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..."

    "Pykus Therapeutics, which makes a device to improve retina surgery, and CozyKin, a company that connects families with trained nannies, also each received $100,000...“It’s never been more clear that ideas — even at the earliest stage — have the power to change the world,” Kiki Mills Johnston, managing director of MassChallenge Boston, said in a statement. “With support from the community, these ideas have since grown into capable, profitable, and sustainable ventures.”"

    "CozyKin has tapped into the sharing economy for childcare by matching local families together and placing them with Montessori-trained nannies that they share. To date, more than 600 families have signed up across Boston, Cambridge and Somerville."

    "CozyKin, a network connecting families with trained nannies is,,, among more than two dozen finalists in this year’s MassChallenge startup accelerator... “It’s amazing to see just how far these companies have progressed in such a short amount of time,” Kiki Mills Johnston, managing director of MassChallenge in Boston, said."

    "We got them all. Across the i-lab, Launch Lab and Life Lab, there’s a total of 145 teams in the fall cohort of the Harvard Innovation Labs. We’re already familiar with some of them... Here’s the full list of the 145 ventures, a fascinating catalog of ideas and goals. CozyKin is Airbnb plus childcare: families sharing great nannies."

    "MassChallenge has named the top 26 startups of its Boston startup accelerator that will compete for a total of $1.5 million in equity-free prizes.


    The 26 startups — which span from high tech and consumer goods to healthcare and social impact — were chosen out of 128 startups that have been working out of MassChallenge’s Seaport space since May. CozyKin creates the sharing economy for childcare by matching local families with Montessori-trained nannies for 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."

    "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."
