Kairos is a portfolio of brands across healthcare and financial services that focuses on making life simpler and more affordable for our generation. We start by identifying the toughest problems and build products to solve them. We have built five Kairos solutions to date: Rhino replaces the security deposit, Cera provides affordable care from the comfort of the home, and Little Spoon is a modern parenthood brand to help keep your kid healthy. Bilt is the first rewards program that lets you earn points on rent. Alloy is a new kind of women’s health brand. Kairos’ 5 brands have a collective market cap of $2.5bn, and we’re currently funding our businesses through our venture studio fund.
