AI21 is a privately-held Israeli AI company (Tel Aviv) that publishes open-weight Jamba models alongside a commercial enterprise platform (Maestro), and it holds SOC 2 and ISO 27001/27017/27018 certifications with a public trust center. However, in May 2026 the company cut roughly 60% of its workforce, terminated acquisition talks with Nebius, and announced it is discontinuing standalone LLM sales to focus on its Maestro agent-optimisation product — a material continuity risk for any customer relying on ongoing Jamba model support or updates.
AI21 cut approximately 60% of its workforce (from ~180 to ~70 employees) in May 2026 and announced it is discontinuing standalone LLM sales, raising questions about ongoing maintenance, support, and future updates for the Jamba model family used by customers.
Acquisition talks with Nvidia (reported 2025) and Nebius (2026) both surfaced and were subsequently denied/terminated, indicating ownership and strategic-direction uncertainty over the past year.
