Optimixed Overview
Optimixed's original report on this story.
Daniel Blum, a product manager at Melio, developed a Claude-powered productivity system integrated with Notion and Cowork that handles his weekly planning, email and Slack processing, and runs self-improvement loops without manual prompting. Blum structured the system around two core rules for powerful AI: contextualizing Claude with voice memos and recurring updates, and using a morning brief that teaches Claude company jargon so internal terminology never slows work down. He built a self-improvement loop that watches his edits, identifies friction points, and suggests new skills to develop. The system handles 70–80% of his workday, and Blum scaled it to other PMs at Melio through a Workstation onboarding plugin that gets employees up and running in 15 minutes; the remaining 20% of tasks still require human judgment or capabilities Claude hasn't yet developed.
