    Founding Story

    Nimbalyst was founded in 2024 by the team behind Evergage, which Salesforce acquired in 2020. The founders—Karl Wirth, Greg Hinkle, Jordan Bentley, and Q—built Nimbalyst to enable users to work more effectively with Claude Code through visual editing and session management. The team leveraged their experience building enterprise SaaS products and personalization platforms to create a tool that makes AI coding more accessible and transparent.
