Tsuga

Tsuga is a Paris-based AI-native observability platform founded in 2024 by Gabriel-James Safar and Sébastien Deprez, formerly of Madumbo (acquired by Datadog). The company deploys a Bring Your Own Cloud (BYOC) observability stack inside the customer's own AWS, GCP, Azure or sovereign cloud so logs, metrics and traces never leave their environment, with OpenTelemetry-based tooling and consumption pricing that aims to avoid third-party ingestion markups. In November 2025 Tsuga emerged from stealth with a $10 million seed led by General Catalyst with Singular and angels; in June 2026 it raised a $35 million (€30 million) Series A led by Singular, with General Catalyst, DST Global Partners, QuantumLight, Picus and Databricks Ventures, to scale go-to-market and its AI agent platform. Early customers include Black Forest Labs, Le Monde, Camunda and Buk.
