Frequently asked questions

What exactly did Cohere announce?

On October 15, 2026, Cohere said it signed a letter of intent to acquire AISLE, an AI cybersecurity startup with operations in San Francisco and Prague that specializes in finding and fixing software vulnerabilities. A letter of intent signals an agreed direction, not a closed deal.

What does AISLE actually do?

AISLE builds AI systems that scan widely used software for security vulnerabilities and help remediate them. Founded in 2025 by Ondrej Vlcek, former CEO of antivirus company Avast, along with co-founders from Google DeepMind and Anthropic, AISLE says its AI found more than 500 new bugs in its first year, including 12 OpenSSL vulnerabilities that were subsequently fixed.

How much is the deal worth?

Neither company disclosed the deal's valuation or financial terms. Reporting on a roughly $20 billion figure in some coverage refers to Cohere's separate, previously reported merger with Germany's Aleph Alpha, not to the AISLE acquisition.

Is this part of a larger pattern for Cohere?

Yes. Cohere has made several acquisitions in 2026, including the Aleph Alpha merger and prior purchases of Ottogrid and Reliant AI. The company framed the AISLE deal as extending its push into European "sovereign AI" and cybersecurity, building on AISLE's existing Prague engineering hub.

Has any source disputed the announcement?

No. Every outlet AI Ledger reviewed — Reuters, BNN Bloomberg/The Canadian Press, The Globe and Mail, Seeking Alpha, and Traders Union — reported the same letter-of-intent announcement with no conflicting account. The only open questions are commercial terms the companies themselves have not disclosed, not whether the agreement was signed.
