The raise will be put towards scaling Tsuga GTM motion and accelerating the rollout of the platform’s AI agents.

Tsuga, an AI-powered observability start-up, has today (23 June) announced the raising of $35m in a Series A funding round. The round was led by existing investor Singular, with additional participation from General Catalyst, Picus, Databricks Ventures, and new investors DST Global Partners and Quantumlight.

Established in Paris in 2024, Tsuga is an observability platform built on a ‘bring your own cloud’ model. The platform enables engineering teams to take stronger control of costs, scalability and data sovereignty. 

The organisation said that the funds raised will help Tsuga scale its GTM motion and accelerate the rollout of the platform, with the aim of powering a new generation of AI agents. Among its client base are companies such as Le Monde, Camunda, Buk and Black Forest Lab.

Commenting, Gabriel-James Safar, a co-founder and the CEO at Tsuga, said: “The incumbents built good businesses on a model that no longer works. Sending your telemetry to a vendor’s cloud made sense when data volumes were manageable and AI was not writing and deploying your code. 

“Neither of those things is true anymore. Every customer we speak to is paying more for observability than they were two years ago and getting less reliable coverage. We built Tsuga to end that.”

In late May, the ‘Global Tech Ecosystem Index’ for 2026 revealed a number of European cities as being among the top 20 densest tech ecosystems in the world, according to innovation tracking platform Dealroom. 

The study tracked start-up ecosystems in 325 cities across 77 countries, measuring scale, per capita performance and growth. Among them was Paris, which stood in eighth position for scale as one of the globe’s most successful technology ecosystems. Other regions that ranked highly for various criteria included London, Tallinn, Munich, Copenhagen and Stockholm.
