I want to tell you the honest version of this story.

Not the polished pitch version. The real one, where the idea came from a lived frustration, where the product started as something people laugh at until they stop laughing, and where the engineering logic of solving that problem led us somewhere none of us expected: designing sanitation infrastructure for a planet 140 million miles away.

It Started With a Problem That Shouldn’t Exist

Bathrooms are one of the oldest solved problems in human civilization. Running water, indoor plumbing, flush toilets, we’ve had versions of these for thousands of years. So why, in 2026, does a packed stadium still funnel 80,000 people through restroom infrastructure designed for a fraction of that demand, with lines stretching through concourses during every halftime, every timeout, every intermission, regardless of which door you’re standing in front of? Why does an elderly person at home alone have to choose between risking a fall walking to the bathroom at 3am or an adult diaper? Why does a soldier on a forward operating base, a disaster relief worker at a flood shelter, or a construction crew on a remote site have to make do with whatever improvised solution is nearby?

These aren’t edge cases. They’re the daily reality for hundreds of millions of people.

The problem isn’t that hygiene and sanitation haven’t been solved. The problem is that they’ve been solved for one person at a time, in one place, with permanent infrastructure. Take away the infrastructure, or double the number of people who need access at the same moment, and the solution falls apart.

That’s the gap Urinup™ was built to close.

The Product We Built First

Urinup™ is a freestanding, dual-occupancy, dual-mode portable hygiene pod on wheels. It weighs less than 50 pounds. It serves two people simultaneously, doubling bathroom throughput without construction, without permits, without touching a single pipe.

It operates in two modes. In Tanked Mode, the unit is completely self-contained, a sealed internal waste tank means you can deploy it anywhere, whether or not there’s any existing infrastructure within miles. In Funnel/Tankless Mode, a hose is positioned near any existing toilet bowl or wall urinal, and liquid flows through in real time as the unit is being used. Nothing is collected inside. Nothing needs to be emptied between uses. No plumbing connection of any kind is made.

Two users. Two modes. Zero installation.

The Women’s Edition (pentent filling in progress). The Men’s Double Edition accommodates two men standing, with full privacy. Both are on wheels. Both are patent pending. Both exist because someone got tired of waiting for someone else to build them.

That’s the product we’re launching. It’s real, it’s in manufacturing development, and reservations are open at capaciflow.com.

But that’s not the end of the story.

The Question That Kept Coming Back

When you design a product around the constraint of no infrastructure, something interesting happens. You start to notice that the list of places where infrastructure doesn’t exist is a lot longer than you first thought.

Military forward operating bases. Hurricane evacuation shelters. Off-grid expedition camps in the Arctic. Construction sites are a hundred miles from the nearest town. Refugee camps housing tens of thousands of people. Disaster zones where every pipe in the city has been destroyed.

And then, almost inevitably, if you’re paying attention, you arrive at the most extreme version of the constraint: a pressurized habitat on Mars, where there is no infrastructure at all, where every system has to work flawlessly without a supply chain, without a service call, and without a second chance.

The question that kept coming back wasn’t could Urinup™ work there. It was: what would it have to become to work there?

The Answer Is Autonomy

A sanitation system for a Mars habitat can’t have a maintenance crew. It can’t wait for a technician. It can’t require a user to manage it between uses or empty a tank manually in a pressurized suit. It has to position itself, clean itself, manage its own waste, and do all of this reliably across years of continuous operation in an environment where temperature swings by 100 degrees, gravity is 38% of what we’re used to, and every failure has consequences.

That’s not a portable urinal. That’s a robotic system. And designing it that way, from the very beginning, with those constraints baked in, means it will also be the most capable, most reliable, operationally independent sanitation system ever deployed on Earth.

Which brings us to the Urinup™ Autonomous Model.

What We’re Building – And Who We’re Looking For

The Autonomous Model is the Men’s Double Edition, evolved. Same dual-occupancy footprint, same dual-mode architecture, but with a full autonomous systems layer on top: self-positioning navigation, sensor-based user detection, automated cleaning and sanitization, smart waste management, privacy shield auto-positioning, and health and usage monitoring.

We’ve been in early exploration discussions with a leading university about the research path forward. We’re pursuing a formal SBIR/STTR federal research grant to fund the engineering work. No autonomous product has been finalized or announced, this is a long-term, multi-phase initiative, and we’re being honest about that.

What we’re not being modest about is ambition.

We are building this with the explicit design intent that it should one day be relevant to NASA Artemis lunar base habitats, SpaceX Starship Mars surface missions, and the generation of off-world infrastructure that will need to exist before sustained human presence beyond Earth is possible.

We’re a founder-stage company. One-person, real IP, provisional patents filed, product in development, and a clear-eyed sense of what comes next. We don’t have a full R&D team yet. We’re looking for people who want to help build it.

If you’re an engineer, a robotics researcher, a faculty member at a research university, a manufacturing partner, or a strategic collaborator who believes this problem is worth solving, we want to hear from you.

A Final Thought

People laugh at the word “urinal.” I get it. It’s not a glamorous category.

But sanitation is infrastructure. Infrastructure is civilization. And the gap between where hygiene infrastructure exists and where human beings actually need to be, in combat, in crisis, in space, is one of the most consequential unsolved engineering problems of the next century.

We started with a portable urinal. We’re ending up somewhere much bigger.

Come build it with us.
