Capturing Valuable Work to Prevent Loss of Billable Time and AI Prompt Knowledge

A small consulting firm identified that valuable work often leaks away unnoticed, such as unbilled time due to under-reporting and loss of effective AI prompts shared informally. They built two products: FillTheTimesheet, which tracks billable hours in real-time to prevent revenue loss, and PromptShip, a shared prompt library that captures and reuses effective AI prompts across teams to improve productivity.
