Istari Digital builds a platform to create an engineering metaverse for design, testing, and certification of physical systems entirely through modeling and simulation. It enables digital twins and digital threads—integrated models that trace a system’s lifecycle—so assets can go from concept to certifiable hardware without physical prototyping. The platform supports model-based engineering and cross-team collaboration to validate assets in a virtual environment before building them, with leadership from defense and government-experienced founders. The goal is to speed hardware development to software-like pace while enabling verifiable virtual testing and airworthiness certification across aerospace, defense, and related industries, reducing time, cost, and environmental impact.

Simplify's Take

What believers are saying

  • Mark Ryland joined May 26, 2026, adding AWS security credibility for agentic AI.
  • July 2026 financing reached $22.6 million toward $40 million, extending runway.
  • Air Force contracts totaled $28.1 million on Flyer Øne and $8.6 million on Industry Øne.

What critics are saying

  • Istari still depends on U.S. Air Force procurement; any 2026 stop-work crushes revenue.
  • Lockheed Martin, Boeing, and others can internalize digital-thread tooling before Istari scales.
  • If the August 2026 round stalls, Istari faces a cash squeeze by 2027.

What makes Istari Digital unique

  • Will Roper and Chris Benson built Istari around Air Force-grade digital certification workflows.
  • Industry Øne links 15 defense contractors without centralizing data, launched May 20, 2026.
  • Flyer Øne targets first digital airworthiness certification with Lockheed Martin and AFRL.

Istari Digital has filed a notice of an exempt offering of securities to raise $40,000,001.00 in New Funding.

Istari Digital has filed a notice of an exempt offering of securities to raise $40,000,001.00 in New Funding. According to filings with the U.S. Securities and Exchange Commission, Istari Digital is raising up to $40,000,001.00 in new funding. The federal securities law requires the notice to be filed by companies that have sold securities without registration under the Securities Act of 1933 in an offering made under Rule 504 or 506 of Regulation D or Section 4(a)(5) of the Securities Act. A company must file this notice within 15 days after the first sale of securities in the offering. For this purpose, the date of first sale is the date on which the first investor is irrevocably contractually committed to invest. Each issuer of securities that sells its securities in reliance on an exemption provided in Regulation D or Section 4(a)(5) of the Securities Act of 1933 must file this notice containing the information requested with the U.S. Securities and Exchange Commission (SEC) and with the state(s) requiring it. If more than one issuer has sold its securities in the same transaction, all issuers should be identified in this filing with the SEC. About Istari Digital Istari Digital is a technology company focused on transforming complex engineering into secure, continuous digital workflows. According to its website, Istari connects tools, teams, and environments so that disconnected processes become continuous, auditable workflows, while organizations retain full control over their data. Its platform enables engineering teams to determine whether systems are secure, validated, and compliant in minutes instead of months, streamlining the entire lifecycle from design through operation. Istari particularly serves air, sea, space, energy, and transportation organizations, helping them securely coordinate, validate, and operate complex systems across distributed engineering environments. The company positions itself as building foundational infrastructure for no-fail industries, aiming to make digital engineering ecosystems and an engineering metaverse a practical reality where technologies can be created and tested digitally, free from real-world constraints.

US Air Force awards $8.6M to Istari Digital for defence industry data collaboration platform

The US Department of the Air Force has awarded an $8.6 million contract to Istari Digital to establish Industry Øne, an initiative aimed at accelerating digital transformation across the Defence Industrial Base. The programme addresses fragmented IT environments and incompatible tools that currently hinder collaboration amongst thousands of defence suppliers. Industry Øne enables secure, policy-enforced access to engineering data without centralising or copying it outside the owner's control. The platform allows organisations to maintain their own firewalls and data sovereignty whilst models interact through controlled interfaces, supporting real-time collaboration and continuous integration. The initiative builds on successful predecessors including Flyer Øne and Model Øne. Istari CEO Will Roper, former Assistant Secretary of the Air Force, said the platform provides the infrastructure the defence industry has been missing.
