The raise will be put towards scaling Tsuga GTM motion and accelerating the roll out 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 AI funding round. The round was led by existing investor Singular, with additional participation from General Catalyst, new investors DST Global Partners, Quantumlight, Picus and Databricks Ventures.

Established in Paris in 2024, Tsuga is an observability platform built on the ‘Bring Your Own Cloud’ (BYOC) model. The platform enables engineering teams to take stronger control of costs, scalability and data sovereignty. 

The organisation has stated that the funds raised will help Tsuga scale its GTM motion and accelerate the roll out 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 any more. 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, marking scale, per capita performance or density and growth. Among them was Paris, which stood in eighth position as one of the globe’ s most successful technology ecosystems. Other regions that ranked highly include London, Tallinn, Munich, Copenhagen and Stockholm.
