An Israeli defense neoprime

Israeli ingenuity.
Built to scale.

We take proven Israeli defense products from frontline innovation to production at scale, as one operating company, for allied customers with repeat demand.

How it works Talk to us

The opportunity

Israel wins in code.
It stalls in hardware.

Israeli engineers turn commercial electronics (COTS) into combat capability. Scaling that into qualified, repeat production is where they get stuck. We add production engineering, qualification, procurement and international sales.

The sweet spot
