Data observability platform Sifflet has raised $18 million in new funding, signaling strong momentum as demand for reliable data infrastructure continues to surge. The round was led by existing investors EQT Ventures and Mangrove Capital Partners, with Capmont Technology joining as a new backer.
Founded in 2021 and officially launching its product in 2023, Sifflet has quickly emerged as a key player in data observability. Its platform stands out for blending technical and business context, enabling companies to monitor data quality and reliability at scale. With this new investment, Sifflet plans to accelerate its expansion in North America and continue advancing its AI-powered platform.
The company has seen rapid growth over the past year, tripling both its customer base and revenue. Notable new clients in 2024 include St-Gobain, Penguin Random House, and Euronext, highlighting Sifflet’s growing appeal across industries.
Sifflet’s unique approach treats data reliability as both an engineering and business challenge, which has resonated with large organizations. Pete Williams, Chief Data Officer at Penguin Random House, praised the platform for providing both depth and usability: “Their AI-native tools don’t just detect issues—they give our team the context to respond intelligently and efficiently.”
CEO and co-founder Salma Bakouk noted that the company’s strategy is aligned with a broader shift in the market. “Reliable data is no longer optional. It’s a core requirement for AI-driven enterprises. With this funding, we’re doubling down on innovation, AI features, and our North American footprint to help more businesses build trust in their data.”
Sifflet’s execution has earned continued investor confidence. “Backing a company once is a bet—backing it three times is conviction,” said Yannick Oswald of Mangrove Capital. “Sifflet is not just building a great product; it’s redefining how data-driven companies should operate.”
To support its next growth phase, Sifflet has added two seasoned executives: Rémi Bastien, formerly of ContentSquare, will scale global operations, while Romain Doutriaux, ex-Pigment, will lead pipeline generation and go-to-market initiatives. Together, they’ll help Sifflet expand its reach and impact within enterprise data teams.
