Josh Sirota, founder of Eragon, has raised $12 million to build an agentic AI operating system for enterprise customers. The company aims to offer the entire suite of business software, including Salesforces, Snowflakes, Tableaus and Jiras, through an LLM interface. Siroata, who previously worked on go-to-market teams at Oracle and Salesforce, believes that future business will be done by prompt. His backers include Arielle Zuckerberg at Long Journey Ventures, Soma Capital, Axiom Partners, and strategic angels Mike Knoop and Elias Torres. Eragon's technical talent includes Rishabh Tiwari, a Berkeley computer science PhD student, and Vin Agarwal, an MIT PhD. The security concerns raised by AI agents are big, but for now, Eragon is now in use in a handful of large businesses and dozens of startups.
