CozyKin

CozyKin provided personal care by matching families to share a Montessori-trained nanny with modern tools. The platform raised over $8 million in venture capital and was acquired by Higher Ground Education in 2020.“Who will take care of my baby when I go back to work?” Millions of new mothers in America asked this question every year as theyincreasingly plan to return to the workforce earlier and earlier. Millennial families struggle to find the right care due to the shortage of childcare, complexity of the search and their increasing desire for cognitively-appropriate care. CozyKin ran the two-sided market between new families and great nannies. Families were grouped based on location, schedule and preferences. CozyKin-employed nannies cared for 2-3 infants at the same time in the private home of these families.For parents, we delivered better quality, convenience, socialization and value than daycares or nannies. We backed this up with easy-to-use tech, 24/7 customer support and our 100% satisfaction guarantee. | $6M / Series A / May 20, 2019 | |
