About Istari Istari Digital builds the connective tissue for defense acquisition. Our platform lets engineering models, simulations, and digital threads move securely across primes, suppliers, and government program offices, so a system can be tested, trusted, and fielded in months rather than years. We work at the center of some of the hardest problems in defense acquisition: getting the right model, to the right person, at the right classification, at the right time. We are a small, senior team, and every hire changes what the company can do next.
