Ex-Datadog founders raise $35M Series A for Tsuga observability
What's the deal? Two former Datadog engineers have raised $35 million in Series A funding for TsugaDealroom has a profile for this one. Try Dealroom →, an observability startup that keeps customer data inside each client's own cloud.
Gabriel-James Safar and Sébastien Deprez sold their previous startup, MadumboDealroom has a profile for this one. Try Dealroom →, to Datadog in 2019, then worked there for years before leaving in 2023.
They founded Tsuga in Paris in 2024, betting the business model they helped build was outdated.
Why now? AI agent loops, automated deployments, and token interactions generate huge volumes of telemetry data that older platforms struggle to handle.
As costs climb, engineering teams sample more data to save money — leaving gaps in coverage. Tsuga runs inside the customer's cloud account on AWS, Azure, Google Cloud, and regional sovereign clouds, so data never leaves their environment.
It charges one transparent rate per gigabyte, avoiding the per-byte fees of legacy platforms.
Singular led the round, joined by General Catalyst and new investors DST Global Partners, QuantumLightDealroom has a profile for this one. Try Dealroom →, Databricks VenturesDealroom has a profile for this one. Try Dealroom →, and Picus Capital.
Total funding now reaches $45 million, following a $10 million seed round in November 2025.
Six months after launching publicly, Tsuga has brought in several million dollars in revenue, with average contracts worth six figures. Clients include Black Forest Labs and French media group Le Monde.
What could go wrong? The competition is fierce. Datadog, the founders' former employer, is worth over $30 billion.
Tsuga must convince customers to abandon entrenched incumbents for a startup barely a year into selling.
The signal: Tsuga's bring-your-own-cloud model is a direct answer to the AI-native observability gap, and its early-stage backers are betting that data sovereignty wins over volume-based pricing. The presence of Databricks Ventures on the cap table is telling — a data infrastructure giant lending strategic weight to a startup whose pitch is keeping telemetry inside the customer's own environment.
