Sifflet raises USD $18 million to expand data observability reach

Sifflet has secured USD $18 million in funding from existing and new investors as demand grows for data observability solutions in Europe and North America.

The funding round includes continued support from previous investors EQT Ventures and Mangrove Capital Partners, and introduces Capmont Technology as a new backer. Sifflet, based in New York, specialises in the provision of data observability platforms that help enterprises address data quality, reliability, and health - key considerations as companies adopt generative AI technologies.

Growth and market presence

Since its foundation in 2021 and the official launch of its product offering in 2023, Sifflet has seen significant traction in the market. The latest investment aims to accelerate the company's expansion in North America and advance its product capabilities. Over the past year, Sifflet reports it has tripled both its customer base and revenue, and has signed customers including Saint-Gobain, Penguin Random House, and Euronext in 2024.

Sifflet attributes its recent progress to a strategy that approaches data observability as both a technical and business challenge. This perspective is resonating with organisations looking to scale AI projects and ensure the reliability of the underlying data.

Industry perspectives

Pete Williams, Chief Data Office of Penguin Random House, commented on Sifflet's role in their data infrastructure:

"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."

Salma Bakouk, co-founder and Chief Executive Officer of Sifflet, outlined the company's ongoing mission in the face of momentum from customers and investors:

"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."

Investor support has remained strong, according to Yannick Oswald from Mangrove Capital Partners, who said:

"Backing a company once is a bet. Backing a company three times is conviction. 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"

Torsten Kreindl, founding partner at Capmont Technology, also emphasised the company's position within the enterprise data sector:

"We invest in category-defining companies built on clarity of vision and execution. 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."

EQT Ventures partner Carl Svantesson 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."

Leadership and product direction

To support continued growth, Sifflet has brought in two industry leaders: Rémi Bastien, previously of Content Square, is joining to scale global operations, and Romain Doutriaux, formerly of Pigment, will lead pipeline generation efforts. These appointments are expected to further sharpen Sifflet's go-to-market strategy and expand its reach among enterprise data teams.

With the combination of new funding, a strengthened leadership group, and reported increases in global demand, Sifflet has announced it will launch its data observability agents in the coming months.
