MITS Accelerator #3

On 2 October, the Ukrainian-American investment group MITS Capital announced recruitment for the third MITS Accelerator batch. Participants will receive $200,000 each — half in cash, half in services.

The six-month programme focuses on counter-drone technologies, software, lasers, missiles, localised critical components, and other defence innovations. Reportedly, several spots are already reserved for startups that received soft commitments from MITS Capital during IT Arena 2025.
