Early PMF Signals and Usage Inflection

In this episode of In Depth, First Round Partner Josh Kopelman sits down with Shachar Hirshberg and Dan Shiebler, co-founders of Artemis, the AI-native security platform that just emerged from stealth with $70M in combined seed and Series A funding. Shachar and Dan unpack how they built a 30-person team in seven months, why AI-native companies are outperforming their AI-enabled counterparts, and why they plan to stay on a texting basis with every customer, even at scale.

In today's episode, we discuss:

• How to interview for AI fluency when building an AI-native startup
• Why founder-market fit is a critical early signal for startup success
• The surprising lesson Dan learned from founder-led sales
• How Dan and Shachar are instilling customer-obsession into Artemis’ culture
• How the two co-founders approach conflict and decision-making
