Sifflet raises $18M to power AI with trusted data as demand for observability soars

Sifflet, the AI-native data observability startup, just secured $18 million in fresh funding. The round was led by existing backers EQT Ventures and Mangrove Capital Partners, with Capmont Technology joining in as a new investor.
The money comes on the heels of a big growth spurt. Over the past year, Sifflet has tripled both its revenue and customer base. Its platform is gaining traction in Europe and North America as companies scramble to clean up their data stacks before throwing AI into the mix. Sifflet’s pitch is simple: if your data is broken, your AI will be too.
Founded in 2021, Sifflet officially launched its product in 2023. What makes the platform stand out is its hybrid focus — it looks at data issues from both a technical and business perspective. That seems to be working. Big names like St-Gobain, Penguin Random House, and Euronext have signed on.
With $18M in New Funding, Sifflet Triples Growth and Targets AI-Driven Enterprises
Sifflet will use the new $18 million in funding to accelerate growth, particularly in North America, where demand is rising, and speed up development on new product features.
As more companies lean into Data and AI to stay ahead, the real challenge isn’t just building the models—it’s trusting the data behind them. That’s where Sifflet comes in.
Over the past year, Sifflet has seen strong traction, tripling both its customer count and revenue. New clients like St-Gobain, Penguin Random House, and Euronext have joined the roster, signaling broader industry confidence in the platform.
While Gartner expects half of all enterprises to adopt data observability tools by 2026, Sifflet is already ahead of that curve. The company’s approach goes beyond just flagging technical issues. It treats data quality as both a business and engineering concern—something more teams are beginning to realize they can’t afford to ignore.
Pete Williams, Chief Data Officer at Penguin Random House, said, “Sifflet has become an essential part of how we ensure data reliability across the business, not just within engineering. What sets them apart is their ability to combine technical depth with real-world usability. Their AI-native approach doesn’t just detect issues, it gives our team the context to act faster and smarter. That’s game-changing at our scale.”
Sifflet’s CEO and co-founder, Salma Bakouk, believes the market is finally catching up to what they’ve been saying all along — data quality isn’t just an engineering problem, it’s a company-wide issue. “At Sifflet, we’ve always believed that data quality is both a technical and organizational challenge, and the market is now confirming that belief. With this new capital, we’re doubling down on product innovation, AI-native capabilities, and North American expansion to help enterprises unlock trusted, actionable data at scale,” she said.
Investors are clearly sold. “Backing a company once is a bet. Backing a company three times is conviction,” said Yannick Oswald from Mangrove Capital Partners. “What Sifflet has accomplished in the past year — tripling their customer base and revenue — is extraordinary. The team is not just creating a new product but defining a new standard for how data-driven companies operate.”
To support the next phase, the company has added two experienced hires: Rémi Bastien (ex-Contentsquare) to lead global operations, and Romain Doutriaux (ex-Pigment) to ramp up pipeline generation.
Capmont’s Torsten Kreindl said his firm was drawn in by the clarity of the company’s focus. “Sifflet stood out immediately: a sharp team solving a complex, enterprise-critical problem with both speed and precision. As AI adoption accelerates, the need for trusted, usable data becomes non-negotiable. We’re excited to support Sifflet as they scale this capability globally.”
Carl Svantesson from EQT Ventures added, “We’ve seen Sifflet grow from a compelling vision into a platform that’s setting a new standard in data observability. The team’s ability to pair deep technical innovation with commercial traction—especially as they expand into North America—is impressive. We’re proud to continue supporting them in this next chapter.”
Looking ahead, Sifflet is planning to roll out its new data observability agents this fall — a key milestone in the company’s roadmap.
The startup works with customers like Carrefour, CMA-CGM, BPCE, Nextbite, ShopBack, Adaptavist, and others that rely on data to drive business decisions. As more enterprises rush to implement AI tools, Sifflet wants to be the safety net that makes sure those tools don’t run on garbage data.
