# Spiros Xanthos

> Spiros Xanthos is the Founder and CEO of Resolve AI, the San Francisco-based agentic AI company building autonomous software reliability engineering at unicorn valuation. A serial entrepreneur who co-created OpenTelemetry, sold two companies (Log Insight to VMware, Omnition to Splunk), and went on to run Splunk's $400M+ observability business before founding Resolve AI in 2024. In under 18 months the company raised $160M, reached a $1.5B valuation, and landed customers including Coinbase, DoorDash, and Salesforce - built on the conviction that engineers spend 70% of their time keeping software running rather than building it.
