About

We build software for the people who keep customers

Lumio SaaS began at a service company that lost its biggest customer and never understood why. Six years on, 1,400 companies use it so that story does not repeat.

Why Lumio SaaS exists

It started with one lost contract

In 2020 the founders’ previous company lost its largest contract — 22% of revenue — and nobody saw it coming. Digging through the data afterwards, every sign was already there: the customer had stopped logging in four months earlier, opened six complaint tickets and paid late twice. The data simply sat in four different systems and nobody joined it up.

The first Lumio SaaS was a colour-coded spreadsheet used in-house. Six months later three other companies asked to share it. Today it serves 1,400 companies and still answers the original question: who do we call first today?

How we work

Three things we do not trade away

We say so when it does not fit

If Lumio SaaS does not solve your problem, we say so in the first review instead of closing the sale.

We answer during working hours

No chatbot runaround. Real people, answering in under two hours on average.

The data belongs to the customer

Export whenever you like, delete on request, and we never use your data to train anything.

Inside the company

What a day at Lumio SaaS looks like

Support sits beside engineering, not in a separate room. Every reported bug has a name against it and a deadline. Every Friday the whole company reads the five harshest pieces of customer feedback from that week.
