Contentsquare started with a cheque smaller than the price of a Paris flat. In 2012 a club of software executives called Seed4Soft put in EUR 400,000 and bought a bet on a student.
Jonathan Cherki was studying at ESSEC Business School in Paris when he began the project inside the school's incubator. He told the French start-up magazine Maddyness in 2024 that he started it as a student. Profiles describe the early work happening in an attic and at home. One weakly sourced profile places his birth in Marseille in 1986, with a grandfather who ran an import business in dried legumes, but that detail should be treated with caution.
It forced the product to pay attention to paying customers, not only to investors.
He had noticed a gap. Brands believed they were offering customers one experience, and customers were having another. A shop owner can see a shopper wander off. A website owner could not, until someone showed where people actually moved the mouse and where they gave up.
The quiet years were long. Seed money in 2012. Then nothing large until June 2017, when a $20M Series A arrived. Five years is a long time to live on a seed round. It forced the product to pay attention to paying customers, not only to investors.
When the money did come, it came fast. $42M in January 2018, $60M in January 2019, $190M in May 2020. Then in May 2021 SoftBank's Vision Fund 2 led a $500M round, then the largest in French tech. In July 2022 a $600M Series F led by Sixth Street, $400M of it equity and $200M debt, doubled the valuation to $5.6bn.
Between rounds it bought its way into a bigger market: Clicktale and Pricing Assistant in 2019, Dareboost and Adapte Mon Web in 2020, Hotjar and Upstride in 2021, Heap in 2023, and Loris AI in 2025. It joined the French government's Next40 list in 2025.
There is a price to buying so much. Combining products and teams across several countries is slow work, and the software market cooled after 2022. Third-party estimates put annual revenue near $370M in late 2024, and about 1,800 people work there.
The takeaway for a first-time founder is the shape of that first cheque. A small seed forced Cherki to build something customers would pay for before the large rounds arrived. When the large rounds came, they were buying proof, not a promise.
