NestAI Joins Finland-Estonia Defence AI Framework Without Budget Commitment
TNW reported that Finland’s Ministry of Defence, the Estonian Defence Forces and Helsinki-based NestAI signed an artificial intelligence cooperation letter with no financial commitment. The framework covers joint development, training and technical cooperation, but it does not name procurement contracts, budgets or deployment dates.

TNW reported that Finland and Estonia have put Helsinki-based NestAI into a defence artificial intelligence cooperation framework, and said the letter of intent links two military organisations with a lab founded in 2025 rather than a signed procurement contract.
The document connects the Finnish Defence Forces’ AI Centre of Excellence with Estonia’s Force Transformation Command and names NestAI as the industrial partner.
The arrangement covers knowledge sharing, joint development, training and technical cooperation.
Finland And Estonia Name NestAI As Industrial Partner
The letter of intent was signed on the last day of June by officials from Finland’s Ministry of Defence, the Estonian Defence Forces and NestAI, according to TNW.
The Finnish Defence Forces’ own announcement stated that the document contains no financial commitments.
TNW reported that NestAI was founded in 2025, now employs close to 200 engineers and scientists, and raised €100m in November from Nokia and Tesi, the Finnish state investment company.
NestOS Targets Unmanned Vehicles And Command Systems
NestAI’s product is called NestOS.
The software layer is meant to sit across unmanned vehicles and command-and-control systems, using an open modular design and learning after deployment.
Peter Sarlin, NestAI’s executive chairman, said European defence forces need artificial intelligence systems that work across national boundaries and continue learning after deployment.
He added that capability evolution should remain “in the hands of the nations who operate the systems.”
Pilots Come Before Wider Defence AI Expansion
TNW reported that the first work strands are adaptive and learning AI, command-and-control decision support, and autonomous and unmanned systems.
The participants are due to identify focus areas, run pilots and assess results before any wider expansion.
Major General Sami Nurmi, Defence Command Finland’s strategy deputy chief of staff, connected the letter to the Finnish Defence Forces’ data and AI strategy, according to TNW.
Major General Viktor Kalnitski of Estonia said operational insight and technical expertise should support responsible adoption in command and control, unmanned systems and adaptive decision support.
Nokia Defence Work Adds A Denied-Environments Test
On 9 July, Nokia Defense and NestAI unveiled a joint capability for denied environments, TNW reported.
The phrase refers to conditions where satellite navigation is jammed, bandwidth collapses and autonomous systems must continue operating.
The report described that launch as the first operational output of the Nokia partnership.
The company's partner list includes the Finnish Defence Forces, Patria and Bittium.
The letter of intent does not name procurement contracts, committed budgets, fielded defence systems or deployment dates for NestAI’s software.
