From CNBC Make It.

In 2015, Katerina Markov Schneider was newly pregnant and on the hunt for the right prenatal vitamin. There were plenty of options available on the market, but none that met her standards. She found most of them to have high levels of heavy metals and too many artificial ingredients.

Schneider decided to take things into her own hands. She quit her job as a venture partner at Atom Factory, an entertainment company, to start Ritual.

Less than 10 years later, the supplement brand has expanded far beyond prenatal vitamins and sold over 25 million bottles of supplements for daily health, better sleep, stress relief and more.
