Episode notes
CoFounder Chemistry Began With A Long First Conversation
- Shachar and Dan met via a mutual acquaintance for a 30-minute coffee that turned into a 4.5-hour walk discussing security and future ideas.
- Their chemistry and shared commitment led to repeated side projects and ultimately co-founding Artemis.
Architect For AI Correctness First
- Design architecture to maximize correctness of AI tools by asking whether decisions increase AI effectiveness.
- Make detectable structural choices that make AI more likely to be correct and easier to debug across codebases.

- Artemis focused on customers with acute pain: upper mid-market and enterprises overloaded by legacy SIEM alerts.
- Those customers lacked detection coverage, creating urgency to replace or augment legacy systems.
