Ex-Datadog engineers Gabriel-James Safar and Sébastien Deprez have launched Tsuga, a Paris-based observability platform, with $10 million in seed funding led by General Catalyst.
The round, announced in November 2025, also featured participation from Singular and notable angels including Amjad Masad (Replit) and Charles Gorintin (Mistral AI, Alan).
Tsuga emerges from stealth as enterprises drown in observability data while budgets stagnate.
Rethinking Observability for the AI Era
Tsuga addresses a critical market gap: telemetry data from logs, metrics, and traces is growing at 30% annually, while enterprise IT budgets grow less than 10%.
Traditional observability platforms like Datadog charge steep SaaS markups and force vendor lock-in, leaving teams with exploding costs and complex fragmented dashboards. Founded in 2024, Tsuga flips this model with a bring-your-own-cloud (BYOC) architecture.
The platform deploys directly into a customer's cloud infrastructure—not Tsuga's servers. This gives enterprises full data sovereignty, predictable costs, and compliance flexibility.
The tech stack is built on OpenTelemetry and open formats, eliminating vendor lock-in while handling petabyte-scale queries. Tsuga's AI-native design helps teams resolve incidents faster with full context, not scattered alerts.
Why This Investment Matters?
General Catalyst's lead signals growing confidence in European infrastructure software and a market rotation away from centralized SaaS models.
The fund's track record in developer tools and enterprise modernization positions it well to advise Tsuga's expansion. This round reflects two major trends: enterprises demanding data residency and compliance controls, and the observability market projected to reach $62.3 billion by 2026.
Tsuga's BYOC approach directly competes with Datadog's market dominance by offering a lower-cost, compliance-friendly alternative.
The company plans to use capital for product innovation, customer success operations, and hiring across London and Berlin to tap European engineering talent.

What's Next for Tsuga?
Tsuga faces the challenge of competing against entrenched players like Datadog and New Relic, but the BYOC model addresses real pain points in enterprise cloud operations.
The team's Datadog pedigree combined with European market focus positions them to capture customers prioritizing data sovereignty and cost predictability.
Over the next 18 months, success hinges on expanding customer wins in Europe and establishing foothold in North America. If execution matches ambition, Tsuga could redefine how enterprises approach observability in the AI era.
