[ABOUT ISTARI DIGITAL]
Istari is a digital engineering software company enabling our customers to turn the physical world into the digital to accomplish their specific mission or business objectives.
Istari was founded with the vision of making open, scalable digital engineering ecosystems a reality – where new technologies and systems are created digitally, free from the real-world constraints of costs and schedules. We are creating the world’s best engineering model sharing platform, allowing our customers to simply and securely integrate their models across different engineering disciplines, organizations, and security levels.
At Istari, we are passionate about our mission of creating the world's first open and scalable industrial metaverse. Whether our customers are designing prototypes, performing virtual testing, or training AI and autonomy for complex systems, we know that going digital will save them time, resources, and reduce their environmental impact.  
While we are a distributed team with most team-members working remotely, we place an emphasis on staying connected and collaborative, prioritizing in-person opportunities to build trust as a team. At Istari, we still believe that trust is best built in-person. To do this, we have an engineering headquarters in Cambridge, MA for focused technical development and several times per year we gather for an off-site that allows us to develop our professional skills and our team relationships.
[VALUES]
At Istari, we live by our values, which include:
Purposeful Autonomy
We value letting people self-organize and self-motivate. 
Our flat structure and lack of meeting clutter are meant to empower individuals and teams to be proactive.
Our autonomy is measured, goal-oriented, and results-driven – not meandering.
Clear objectives help us prioritize our time.
Smart Transparency
We believe in honest-but-kind communication, transparency, and open-door policies.
We love learning about challenges and tackling them early, not hearing good or bad news late.
We share work-in-progress across our team. 
Fast feedback keeps autonomy purposeful.
Continual Curiosity
At Istari, we love learning to do things ourselves.
We ask, read, share, teach – even watch YouTube videos – to learn new skills to solve problems.
When we make breakthroughs, we write them down.   
Writing focuses ideas, helps us learn, and helps us share.
