Startup Feature: Blean Is Solving the Menstrual Cup’s Public Bathroom Problem

Reusable period products only work if they work everywhere you go. In this Periodwise startup feature, meet Blean, a young company building a portable device for cleaning menstrual cups and discs away from home, and Paula León, the medical device designer behind it.

Ask anyone who loves their menstrual cup when their confidence wavers, and you will usually hear the same story. It is not insertion, and it is not the learning curve. It is standing in a public bathroom stall, cup in hand, realising that the only sink is on the other side of the door, next to a row of strangers. Every option from there is a compromise: wipe it with toilet paper, rinse it with a water bottle balanced on one knee, or carry it to the shared sink and hope nobody looks over.

Blean, a startup based in Raleigh, North Carolina, exists because of that exact moment. The company is developing a portable device that lets you clean a menstrual cup or disc discreetly wherever you are — at work, at the gym, while travelling, or outdoors — instead of only where there happens to be a private sink.

The Problem Nobody Designed For

Menstrual cups and discs have a lot going for them. They hold more than a tampon, they can stay in for up to twelve hours, and a single cup can replace years of single-use products, which is why they sit at the heart of most sustainable period routines. We cover the wider landscape of those options in our guide to sustainable period products, and the pattern there is consistent: the products themselves are good, and the barriers to using them are almost all practical.

The biggest practical barrier is the away-from-home empty. At home, you tip the cup into the toilet, rinse it at your own sink, and reinsert. In a public bathroom, the sink is shared, the stall has no water, and the whole routine collides with the stigma of doing anything visibly period-related in front of other people. Plenty of would-be cup users try one, hit that wall on their first long day out, and go back to disposables. The product did not fail them; the bathroom did.

It says something about how period care gets designed that this problem has been left to workarounds for as long as cups have existed. Blean is one of the first companies to treat it as a product problem worth solving on its own — on its about page, the company describes its mission as making reusable menstrual products realistic for everyday life, not just for days spent near your own bathroom.

What Blean Is Building

Blean is still pre-launch, so the company is keeping the finer details of the device close. What it has shared publicly: the device is portable, it is designed for cleaning menstrual cups and discs in public settings, and the goal is privacy, convenience, and confidence when you are on the go. Think of it as the missing piece of kit between "I love my cup at home" and "I trust my cup anywhere".

The company is currently building high-fidelity prototypes, alongside early partnerships with menstrual cup brands, health educators, and nonprofits. If the device delivers on the pitch, it removes the single most common practical objection to switching to a reusable product.

The Designer Behind It

Blean is founded and led by Paula León, an industrial designer with a master’s degree from North Carolina State University who specialises in medical device design for women’s health. That background matters: this is not a marketer who spotted a niche, but a designer whose day job is the engineering of devices for bodies, applying that training to a moment of period care that mainstream product design has ignored.

León has been open about what drives her. She wants sustainable menstrual care to be genuinely accessible, so that anyone can manage their period with confidence rather than working around it, and she sees breaking period stigma as part of the product brief, not a side effect. In her NC IDEA founder interview, she describes the fulfilment of “creating a unique product that currently has no equal in the market”.

Her work is starting to collect recognition. Blean received an NC IDEA MICRO grant in fall 2024, a competitive award for early-stage North Carolina startups, which is funding product validation and business model work. León has also been supported by the Miller Fellowship through NC State’s entrepreneurship program, and her design work has been recognised within the Industrial Designers Society of America (IDSA) community.

Why This Matters for Period Care

Periodwise spends most of its time on pain, symptoms, and treatment decisions, so a cleaning gadget might seem off to the side. It is not. The choice of period product shapes daily comfort, cost, and waste for decades of menstruating life, and right now that choice is skewed by infrastructure: disposables win not because they are better, but because the world is built for them. Every public bathroom has a bin; almost none has a private sink.

Companies like Blean chip away at that imbalance. When the practical barriers fall, the decision between a cup, a disc, and a disposable becomes what it should have been all along: a question of what suits your body, your flow, and your day.

Where to Follow Blean

The device has not launched yet. You can sign up for updates at bleanhealth.com, or follow along as the company shares its progress toward launch: @blean.health on Instagram, @bleanhealth on TikTok, and Blean on LinkedIn. We are featuring the company because it is doing careful design work on a real, unglamorous problem, and that is exactly the kind of period care work that deserves an audience.
