Flex partners with Clue on HSA and FSA access

Flex partners with Clue to make Clue Plus eligible for HSA and FSA spending in the US, letting users pay for menstrual health tools with pre-tax funds.

HSAs and FSAs are US pre-tax accounts for eligible health costs. Announced on 16 December 2025, the move makes Clue Plus available via these benefits, with Flex citing potential savings of 30 to 40 per cent.

Clue Plus offers personalised cycle tracking, deeper analysis, advanced predictions and hormone insights, with options for pregnancy and perimenopause. It includes 12-month forecasting and clinician-backed guidance.

“At Clue, our mission is to empower women and people with cycles with trustworthy, science-based information about their menstrual and reproductive health,” said Rhiannon White, CEO of Clue. “Partnering with Flex allows us to make Clue more accessible to the millions of people who rely on our app for insights into their bodies. We’re thrilled to expand access through HSA/FSA eligibility.”

Flex says more than US$150bn is held in HSA and FSA accounts, and the partnership brings reproductive health purchases into standard benefits checkout.

“At Flex, we believe everyone should have affordable access to women’s healthcare,” said Sam O’Keefe, CEO of Flex. “After my own pregnancy and postpartum experience, I saw firsthand how confusing and hard to navigate women’s health can feel. Making Clue eligible for HSA and FSA spending is one way we are helping more people use their pre-tax dollars to access tools that provide meaningful data and insights into their health.”
