Of the companies that claim to be committed to the planet, how many actually do? Founders of Nota Climat in Paris in 2021, Elsa Chai and Vincent Pappolla, former strategic consultants of KPMG, analyzed the data and figures of the CSR of a hundred companies with more than one billion euros in turnover, for a total of 500 brand names. The goal: to make their carbon emission trajectories available in a free application launched in May. The application, which now has 5,000 users, also allows everyone, with a swipe, to condemn or applaud the policy implemented. To make the brands move – and close the circle -, “we are building partnerships with associations, media, to make these data resonate”, explains Elsa Chai, who would find herself inside “Yuka for the climate”. The start-up expects to launch a platform in September where the companies’ CSR data will be listed, all in the same format, in order to facilitate comparisons.

To build a website, UX designers are used to face-to-face tests with users, in order to collect and analyze their reactions. To save them time, money and data, Odaptos has developed an artificial intelligence that automates these tests by tracking, on video, both what is said and the emotions and facial expressions of the interviewee. A report is then generated in less than an hour. “The average basket is 1500 euros for 10-30 interviews of thirty minutes against 20,000 usually”, assures Maximilien Joannides, co-founder. The economic model is based on a credit system (50 euros = 30 minutes of interview). Created in late 2020, supported by the Occitania region – its 3 employees and 4 freelancers work in Montpellier and elsewhere – the start-up launched the beta version of its tool the following year, then began its commercialization. earlier this year., with UX companies and agencies. With 2 VivaTechs and 1 CES in Las Vegas, it is currently raising € 500,000 for development.

The Rennes Sweetch Energy start-up is an offshoot of the CNRS projects on osmotic energy. Kesako? Water always passes from the least concentrated medium to the most concentrated medium, for example in salt. This is what causes the exchanges between the cells in our body. But extend this effect to large amounts of water, in estuaries, between a salty arm of a freshwater river and the sea, and you can recover energy. Or mechanical, by capturing the movement of water to make the turbines spin (low efficiency), or even directly electrical, managing to capture the exchanges of ions (charged particles) between the two media, through special membranes. With its osmotic power plant projects, Sweetch Energy could develop additional electricity. In France, the total potential would be 1.25 GW. But in South American countries, on the Amazon River, the supply of electricity could be over 100 times higher.
