So that's the metrics we will tackle next.

But right now we are more in this expansion space, grab as much land as possible in terms of getting our hardware into as many buildings as possible.

Yeah, it's a year.

uh well that depends a bit uh if you calculate purely the doors it's a different story we we now see upsell as i mentioned we not only do doors that's just the first step and then all the rest is wirelessly so we can upsell basically in a kind of a self-service so customers can buy their own sensors somewhere let's say in china bring them in the building we see them connected and then uh we add the you know the the fee for that um so customer acquisition cost uh is

It's really hard, look, it's enterprise sales, yeah?

So that has a high, how do you say, variance, right?

It can be, it's an inbound, they want us, they heard, word of mouth, and then it's near zero, and on the other, no, just the marketing cost.

And on the other end, we have things where we do workshops and this and that, and you look at several thousand euros CAG, right?

10K?

Yeah, yeah.

I'm just calculating, yeah, because I'm wondering, you know, the point is...

How long do I keep a customer?

Like from my current perspective, it's almost like unlimited because the building has a lifespan of, you know, 30, 40 years and the hardware is open hardware.

So it's standard hardware.

So, you know, it's a quad core processor based on the Pi compute platform.

So it's nothing where I would say they're going to churn out.

So if you can bring that in, you know, but I don't want to calculate.

So that's what I was just going on my head.

Do I calculate 20 years of recurring revenues?

But yeah.
