You're In Business
The Crypt is an innovative personal knowledge management system with excellent problem-solution fit and strong technical execution, tackling context-switching in professional workflows. However, as an early-stage project primarily built for and used by its creator, it currently lacks verifiable audience reach, active user adoption, and measurable business traction, appropriately placing it in the minimal traction tier.

Description
An AI-augmented knowledge management system built on Obsidian that runs a multi-client professional practice. Structured markdown vault with an agent layer that handles media monitoring, meeting processing, client file updates, and daily briefs. Includes Tome, an open source macOS app I built for local meeting transcription that feeds the vault.
Audience Reach
Early stage. The Crypt is a personal system I use daily to run my practice. Tome, the open source component, was released publicly on GitHub this month. The LinkedIn article announcing the project reached ~2,000 followers on day one, with submissions pending at HBR, Fast Company, and Hacker Noon. Expecting reach to grow significantly as those publish and I hit Product Hunt and Hacker News in the coming weeks.
Target Users
Senior professionals managing complex, multi-client or multi-file workloads where context switching is the primary productivity drain. Consultants, lawyers, policy advisors, communications professionals, anyone whose value depends on connecting information across conversations, stakeholders, and time. Particularly relevant to people already using Obsidian or similar local-first knowledge management tools who want to wire an AI layer into their existing workflow.
