Data Observability Platform Sifflet Raises $18 Million.

Led by Salma Bakouk(CEO), Wissem Fathallah(Chief Product Officer), and Wajdi Fathallah(CTO), Sifflet has raised $18 Million in funding from existing investors EQT Ventures and Mangrove Capital Partners as well as a new joiner, Capmont Technology. Sifflet has appointed industry veterans Rémi Bastien (ex-ContentSquare) and Romain Doutriaux (ex-Pigment) to lead global operations and pipeline generation, accelerating its go-to-market strategy.

As Data & AI become core to enterprise strategy, Sifflet ensures the reliability of data powering these initiatives at scale. Over the past year, the company has tripled both revenue and customer base—adding leading names like Saint-Gobain, Penguin Random House, and Euronext.

The new funding will fuel product innovation, AI enhancements, North American expansion, and team growth across engineering, sales, and marketing.
