About Us

Our mission is to provide people with personalised support along life’s critical journeys.

73% of parents don’t feel supported by their employer. Kami wants to change that statistic, and is already helping large organisations such as JP Morgan and Meta (Facebook) turn the tide.

Kami ensures employees receive the specialist coaching, emotional, and professional support needed, on family planning and fertility through to pregnancy, parenting, returning to work and beyond. Kami empowers people to reduce burnout, improve work/life balance and reach their career goals.

We’re a growing, dedicated team of experts in Machine Learning, NLP, Psychology, Coaching, and Family Support. Our parenting consultants and digital platform deliver tailored support to our diverse user base spanning individuals, established families and everyone in between.

To date we’ve been backed by Google, Microsoft, Innovate UK, and Founders Factory, who recognise the potential impact we can have on supporting the wellbeing of families and wider society. And we’re just getting started.

Through our matched-subscriptions policy we have also pledged to help tens of thousands of low-income families get the support they need.
