Toronto's Cohere signed a letter of intent on October 15, 2026 to acquire AISLE, a Prague-based AI cybersecurity start-up whose 50 staff will form Cohere Cyber.
What Happened
Cohere, the Toronto-based artificial intelligence company, said on Thursday, October 15, 2026, that it has signed a letter of intent to acquire AISLE, an AI cybersecurity start-up with its engineering base in Prague. Cohere plans to combine AISLE's autonomous security research with its own AI models and to set up a new unit, Cohere Cyber, to be led by AISLE chief executive Ondřej Vlček as senior vice-president. All of AISLE's roughly 50 full-time employees are to join Cohere, an AISLE spokesperson said, and the Prague hub will become Cohere's Prague office. Financial terms, the structure of the deal and the expected closing date were not disclosed, and the deal has not yet closed.
Key Facts
- Buyer: Cohere, based in Toronto, which builds AI models for businesses and governments.
- Target: AISLE, an AI cybersecurity start-up with its engineering hub in Prague; some reports describe it as split between San Francisco and Prague.
- Status: letter of intent signed, announced October 15, 2026; terms not disclosed and deal not closed.
- People: about 50 full-time AISLE employees to join Cohere; CEO Ondřej Vlček to lead a new Cohere Cyber unit.
- Plan: pair AISLE's autonomous security research with Cohere's foundation models.
- Context: the deal is part of Cohere's push into Europe, alongside its merger with Aleph Alpha.
Why It Matters
AI is changing cybersecurity on both sides. Attackers use AI to find weaknesses and write convincing scams faster, and defenders are turning to AI systems that can hunt for security flaws on their own, around the clock. AISLE's focus on autonomous security research, using AI to find and analyse vulnerabilities, puts it in the second camp. By buying it, Cohere gets a specialist team and a ready-made product line in one of the areas where companies are most willing to spend on AI.
The deal also says something about how AI model makers plan to compete. Building a general-purpose model is no longer enough; companies are bundling models with specialist products that solve a specific, costly problem. Security is a natural fit for Cohere, which sells mainly to businesses and governments that care about keeping data under their own control. Cohere has framed its offer around sovereignty, the idea that customers, and countries, should be able to run AI without depending on a few foreign platforms.
Europe is the other part of the story. With its Aleph Alpha merger and now a Prague office, Cohere is building a presence on the continent, and reports describe the AISLE deal as part of that European push and of its offer of sovereign AI.

Impact
Short-term: The two companies will work towards a final agreement. AISLE's team is set to become Cohere Cyber and Cohere's Prague office, though details depend on the deal closing.
Long-term: If completed, the deal gives Cohere a cybersecurity business to sell alongside its models, and strengthens its European base. It adds to a wave of AI companies buying specialist start-ups to move from general models to products that customers pay for directly.
Who is affected: AISLE's employees and investors, Cohere's enterprise and government customers, rival AI security start-ups, and European organisations that buy AI services.
Key Takeaway
Cohere has signed a letter of intent to buy Prague-based AI security start-up AISLE, whose roughly 50 staff will form a new Cohere Cyber unit, as it builds products and a European base around its AI models.
