On 23 September 2025 we were at BIG, the annual event held by Bpifrance and the largest gathering of entrepreneurs in Europe. The theme of this edition was truth. And the question put to everyone: what is truth to you?
Want to know more about the Molleaumètre?
Thirty minutes to discuss your situation and estimate the potential hot water savings.
Our answer: what you do not measure, you do not change
For Molleau, the answer comes down to one line: truth means making the invisible visible. In the shower, nobody knows how much water they are using at the moment they use it. As long as that figure stays hidden, it bears on no decision at all. The Molleaumètre puts it in front of you, in real time, through a light ring.
And the field results bear that out: 23% less consumption per shower measured in a residence, and up to 61% less among the heaviest users. Not by inducing guilt, not by cutting the flow: simply by telling the truth, continuously.
Organised by Bpifrance, BIG brings together tens of thousands of entrepreneurs, executives and ecosystem players each year for a day of talks, meetings and introductions. An ideal place to test your thinking and meet future partners.
The day also extended an already concrete relationship with Bpifrance, which has supported Molleau through its innovation grant and incubation schemes. We cover this in our support journey.
Our thanks to Bpifrance and the BIG Média team for the coverage.
