Bridging the gap between circular entrepreneurs and the financiers who fuel them.

Our story

Right now, most businesses make money by selling as much stuff as possible. Products that break fast, get tossed out even faster, and leave behind a giant mess for the planet.

But what if we could flip the script?

What if businesses earned money by fixing, upgrading, and reusing products over and over again—a circular model?

Here’s the catch: whether a product can be reused infinitely depends on the quality of its parts. So, it’s about everyone in the value chain showing up.

That’s why collaboration is key.

So, circular models? They’re all about businesses collaborating and retaining value together, again and again.

Sounds great, right? But here’s the deal:

→ Most businesses struggle to figure out how to set up such a circular business model.

→ And financiers are hesitant to invest—it’s a whole new way of making money.

That’s where we step in.

At cise.network we create tools —financial models, legal contracts, and educational content—that help businesses make circularity profitable.

And we make sure financiers understand how to invest in such new, circular businesses.
