Tsuga

Tsuga is an enterprise observability platform for logs, metrics, traces and application performance management that uses a bring-your-own-cloud (BYOC) architecture: the data plane is deployed inside the customer's own cloud account, with telemetry stored in the customer's object storage and encrypted with the customer's KMS keys. Tsuga operates the software remotely through a control plane connected over mutual TLS, so the customer retains physical and legal control of the data while Tsuga retains operational responsibility. The company's website states that deployment into an AWS account is done via infrastructure-as-code in under two hours, and the Series A announcement describes deployment across Microsoft Azure, AWS, Google Cloud and regional sovereign clouds.

The product set spans log management, application performance management, infrastructure monitoring, observability pipelines and a sensitive data scanner, together with dashboards, alerts and AI-powered workflows. Tsuga positions itself around three buyer needs: scale (avoiding sampling, retention cuts or dropped regions), sovereignty and resilience (telemetry that cannot leave the cloud perimeter, including source code, session tokens or LLM prompts), and governance (SSO, RBAC, team boundaries, retention policies and audit logs built in from ingestion to query). For AI workloads, the platform presents application and infrastructure traces alongside AI agent traces, prompt and token visibility, confidence metrics and agent call graphs, and runs automated root cause analysis on unsampled data; an MCP server and CLI let customers build their own agents inside their security boundary. The company describes its stack as relying on open-source collectors such as OpenTelemetry and open data formats to avoid lock-in.

Founding story

Co-founders Gabriel-James Safar (CEO) and Sébastien Deprez previously founded Madumbo, which was acquired by Datadog, and subsequently led product and engineering initiatives at Datadog. Their stated motivation was that SaaS observability pricing scaled with hosts and gigabytes while control and compliance requirements pushed against sending telemetry to a third-party cloud, so they founded Tsuga in 2024 in Paris to run an enterprise observability platform inside the customer's own cloud account.

Business model

Tsuga describes itself as a combined software and service business. It sells a managed platform whose compute and storage run on the customer's own cloud bill, so Tsuga does not resell or mark up infrastructure. Each account includes a named forward-deployed field engineer who works inside the customer environment to tune pipelines, retention policies and access, and to reduce infrastructure spend. [0][6]

A single flat rate per gigabyte ingested/consumed, with retention included, unlimited fields and no per-host charge; the underlying EC2, S3 and equivalent infrastructure costs are paid directly by the customer to their cloud provider. The Series A announcement states costs fall over time as forward-deployed engineers tune the environment. [0][6]

Traction

Six months after exiting stealth, Tsuga reported several millions in revenue with average contract values in six figures, and customers including Black Forest (frontier model lab), Le Monde, Camunda and Buk. Prior to its public launch the company said it had design partners and customers among frontier technology companies, financial institutions and media leaders. [6][7]

Latest developments

Tsuga announced a $35 million Series A led by Singular with participation from General Catalyst and new investors DST Global Partners and Quantumlight, plus Picus and Databricks Ventures. Proceeds are directed at scaling go-to-market and accelerating the rollout of the platform for AI agents, including unified AI agent tracing, prompt and token visibility, automated root cause analysis, and an MCP server and CLI.
