“I joined for the Private Key Storage Checklist after a messy laptop migration. The ‘travel kit’ section in Module 3 made me stop carrying a plaintext seed card in the same bag as the hardware device. Still annoyed that the live sessions are late for Europe, but the recordings are clear.”

“★★★★☆ — Solid on labeling and recovery timing. Wanted deeper multi-sig tooling. The mild reservation: office hours fill quickly in busy months.”

“Anonymous client in logistics software: Our Team Drill Day exposed that only one engineer knew where the passphrase shares lived. We rewrote the escalation doc the same afternoon.”

“Short take: the seed backup mistakes article matched what we were doing wrong with cloud photos. Checklist Kit was enough for me; I skipped the cohort.”

Case study: Solo founder, three wallets

A founder in Gyeonggi enrolled in Vault Cohort after losing a week reconstructing which metal plate matched which account. Through Module 2 they built a single storage map with hashes of device serials (not seeds) and a verification date. During the recovery rehearsal they restored a test wallet in 19 minutes—down from an estimated hour of guessing.

Outcome tracked: clearer inventory, not investment performance.

Case study: Four-person ops desk

A small desk used Team Drill Day to practice a laptop-loss scenario. They discovered their shared password manager held a partial seed photograph. The facilitator stopped the drill, documented the finding, and the team rotated that material offline before continuing. Follow-up summary included a new “no seed media in SaaS vaults” rule.

Limitation noted by participants: drills assume you already own hardware devices; purchasing guidance is out of scope.
