A letter from Willo's CTO

To those that are curious,

For most of my research career, I believed that the last few meters of electricity was an unsolved frontier. Humanity built incredible solutions for power generation, electricity storage, and renewable energy. But the final step, the moment when electricity meets our devices, remained the same: a cable, a connector, or a surface charger.

Every engineer learns to work around this limitation. Every product is constrained by it. Entire industries have had to adapt to it.

But I kept wondering: *What if that final cable didn’t need to exist?* What if devices could move freely, in the air, at any angle, and still receive power effortlessly?

For years we moved through a mix of small wins and unexpected setbacks, learning a little more each time. Some experiments worked, others didn’t, and the path to answering my question kept moving.

And then, eventually, everything changed when our research team discovered a breakthrough solution.

We discovered a new way to deliver power through the air while devices are moving, rotating, shifting, and behaving like they do in the real world – with full misalignment tolerance, no line of sight, no pads, no ports, and no mechanical contact.

This breakthrough is not just a shift in product design, it’s a shift in infrastructure. The same kind of shift that happened when Wifi set us free from RJ45 ethernet cables.

And now, the last meters of electricity are ready for the same transformation.

I picture workspaces where our tools are always powered. Warehouses where fleets never pause. Factories that have zero downtime. Robots that move with complete freedom. Homes where devices simply work. Hospitals where equipment is always ready. Drones that never need to land.

And countless other places where cables limit our lives.

This isn’t a metaphor. It’s engineering. And engineering, at its best, is the careful removal of constraints we once assumed were permanent.

We are at the beginning of a long journey. We will keep building. We will keep learning. And we will keep pushing this frontier until power becomes as ambient as air itself.
