Tsuga, a Paris observability company, raised a $35m Series A announced on 23 June 2026. Singular led the round. General Catalyst returned as an investor, DST Global Partners and Quantumlight joined, and Picus and Databricks Ventures took part. The company did not disclose a valuation.
The round came about six months after a $10m seed raised in December 2025. The Next Web puts total funding at about $45m.

What Tsuga does
Tsuga offers an observability platform for the AI era that is deployed and run inside each customer's own cloud, so telemetry and AI workloads stay under the customer's control. Co-founder and chief executive Gabriel-James Safar wrote in the announcement: "Observability has been running the same playbook for decades."
He added: "Because telemetry never leaves the customer's environment, the AI built on top of it never has to either." The company's customers include Le Monde, Camunda, Buk and Black Forest Labs. Le Monde used Tsuga to monitor its infrastructure during the French municipal elections, while Camunda and Buk run the platform across multi-cloud environments with strict data residency requirements, and Black Forest Labs uses it to observe AI workloads.
Tsuga is a Databricks partner, and customers can route observability data into Databricks.
The founders and traction
The Next Web names the founders as Safar and Sebastien Deprez, who sold their company Madumbo to Datadog in 2019. Tsuga launched in December 2025.
The company says it has contracted "millions in ARR" and that its average contract value is in the six figures. The Next Web labels those figures as company-stated and unaudited. Neither source gives a headcount.
What the money is for
Tsuga said it will grow its team efficiently and speed up platform rollout. Specific areas are forward-deployed engineering, a Skills library, an MCP server and an agent-building toolchain. Safar wrote: "Your teams build the agents. We make sure they work with SRE-grade intelligence and stay under control."
The Next Web adds that the company plans to expand the team and build the agent tooling.
Funding history
Singular and General Catalyst backed the December 2025 seed, according to the Tsuga announcement. With the $35m Series A, funding now totals about $45m by The Next Web's count. Tsuga's pitch, that data should stay inside the customer's cloud, is aimed at companies that worry about sending telemetry to a vendor's cloud.
Tsuga's announcement lists the investors' roles: General Catalyst returning, DST Global and Quantumlight new, and Picus and Databricks Ventures also joining. The Databricks tie is commercial as well as financial, since customers can send Tsuga's observability data into Databricks. The Next Web reports that the founders sold Madumbo to Datadog in 2019, so they know the incumbent's market from the inside.
Tsuga is based in Paris and made its announcement from there on 23 June 2026. It did not give a valuation or an employee count, and the revenue and contract figures above are the company's own.
