French deeptech startup Tsuga has emerged from stealth with €8.7 million in Seed funding to bring its AI-native observability platform to market.
The round was led by General Catalyst, with participation from Singular and prominent angel investors including Amjad Masad (Replit), Charles Gorintin (Alan, Mistral AI), Jonathan Benhamou (Resilience), Olivier Bonnet (BlaBlaCar), and Philippe Corrot (Mirakl).
Founded in 2024 by Gabriel-James Safar and Sébastien Deprez — both veterans of Datadog, following the acquisition of their previous company Madumbo — Tsuga is building a Bring Your Own Cloud (BYOC) observability platform that combines the simplicity of SaaS with the control and efficiency of on-prem infrastructure.
“Our goal with Tsuga was to build the last observability platform today’s and tomorrow’s tech giants will ever need,” said Gabriel-James Safar, CEO and co-founder. “It’s built on crisp principles: Bring Your Own Cloud, open-source first, and giving teams the freedom to define their own rules to move faster.”
Tackling observability’s scaling crisis
Enterprise data volumes have exploded — logs, metrics, and traces are growing roughly 30% year-over-year, while IT budgets expand at less than 10%. AI-driven development has only intensified the problem, as autonomous code and ephemeral microservices generate unprecedented amounts of telemetry data.
Current observability stacks can’t keep up. They’re costly, fragmented, and plagued by blind spots that threaten reliability and compliance.
Tsuga’s solution is a new observability foundation built for the AI era — one that’s:
- AI-native and hyper-scalable, capable of ingesting massive data volumes in real time,
- BYOC-based, giving companies ownership of their data and infrastructure,
- Cost-transparent, preventing runaway billing, and
- Open-source compatible, avoiding vendor lock-in.
Its proprietary architecture enables businesses to “see everything, without compromise”, maintaining data integrity and speed while reducing infrastructure overhead.

From Datadog alumni to a new European observability powerhouse
Tsuga’s founding and early team brings deep observability expertise. In addition to Safar and Deprez, the startup includes Nils Bunge (former Director of Product Management at Datadog) and Valentin Jacquemont (among Datadog’s first European hires). The wider team hails from companies like Palantir, Cognition, and other top-tier infrastructure firms.
“Our mission is simple,” said Safar. “To turn observability into a competitive advantage — one that’s hyper-scalable, intelligent, and fully in a company’s control.”
The startup plans to use its Seed funding to expand its engineering and customer success teams, accelerate product development, and prepare for broader European rollout in 2026.
Riding Europe’s data infrastructure wave
Tsuga’s raise follows a growing wave of European startups reinventing observability and data management for the AI era — including Sweden’s Rerun (€15.6M), Ireland’s Bronto (€12M), and Switzerland’s Qala AG (€1.7M).
While France has been relatively quiet in the observability space, Tsuga’s emergence signals renewed confidence in French deeptech teams tackling infrastructure-level challenges with global potential.
“Observability must evolve beyond dashboards and alerts,” added Safar. “It’s about enabling engineers to act faster, smarter, and at scale. Listening to what they need — and building exactly that — will remain our top priority.”
