Our shared values
- Lead with Intention: Leaders are made not born. Leadership is a practice of intention. And through that intention is how we will ultimately succeed in realizing our mission and vision.
- Embrace Accountability: We are imperfect in our actions, results, and even sometimes our intentions. By making accountability a practice, we destigmatize failure, increase trust with others, and accelerate learning both at the individual and the team level.
- Practice a Growth Mindset: Growth comes at the edge of our comfort zone. We repeatedly place ourselves there by risking failure and embracing the challenges that failure presents us to own our growth and support others in theirs.
- Be You: We want people to show up as they are because that creates a healthier, more dynamic, and effective work environment. Just as much to do with being oneself, it’s everyone’s responsibility to create space for others to be their authentic self as well.
About The Flex Company
The Flex Company was founded by Lauren Wang after years of experiencing recurring infections linked to traditional tampon products. When she began researching menstrual care, she discovered the category had seen almost no meaningful innovation in nearly a century. Convinced women deserved better, Lauren founded Flex to redesign period care from the ground up.
Flex created the menstrual disc category in 2016 and has since sold more than 150 million discs, becoming the #1 selling modern period care brand in the U.S. Today, Flex’s award-winning products are available in more than 30,000 retail stores, including Walmart, Target and CVS. Based in Venice, California, Flex designs its disc and cup products in-house and manufactures in the U.S. and Canada.
