Highlights
- Cohere signed a letter of intent to acquire AISLE, integrating AI-powered cybersecurity into its $20 billion merger with Germany's Aleph Alpha.
- The acquisition expands Cohere's European presence via AISLE's Prague engineering hub and targets enhanced security solutions for enterprise and public sector clients.
- AISLE's AI discovered over 500 new software bugs, including 12 OpenSSL vulnerabilities, in its first year under founders from Avast, Google DeepMind, and Anthropic.
Acquisition broadens security and European reach
As reported by Reuters, Cohere said on Thursday it had signed a letter of intent to acquire AISLE, an AI cybersecurity startup that detects vulnerabilities in software. The company said the transaction would add cybersecurity to the business entity it is assembling through its merger with Germany's Aleph Alpha, a combination reported to be worth about $20 billion.Cohere said the acquisition reflects its continued investment in Europe and would deepen its presence across the region. The deal also extends its European footprint through AISLE's engineering hub in Prague.
The planned tie-up is aimed at strengthening the combined group's security and threat detection capabilities for enterprise and public sector clients. Cohere said private deployment would be available on the customer's own system.
"Increasingly capable AI systems are transforming both cybersecurity and the threats organizations face, and defensive capabilities must advance just as quickly," Cohere said.
AISLE adds founding pedigree and vulnerability research
AISLE was founded in 2025 by Ondrej Vlcek, the former chief executive of Czech antivirus maker Avast, alongside co-founders from Google DeepMind and Anthropic. The terms of the deal were not disclosed.AISLE said its AI found more than 500 new bugs in widely used software in its first year, including 12 vulnerabilities in OpenSSL, a free program used to encrypt internet traffic for banks, governments and messaging apps. Those vulnerabilities were fixed after their discovery.
In our earlier coverage of AI mega-rounds reshaping venture capital, we explained how fundraising is concentrating into fewer, larger deals as AI start-ups capture an outsized share of global venture funding. We noted that this shift is forcing investors to write bigger cheques to a smaller number of companies, raising concentration risk while intensifying competition as corporate players also push into the space.
