Foundation Sprint Brief: Brainshelf Book Catalog
Scenario
The Brainshelf team has a Go verdict (with one yellow flag on competitor research, closed by Riley’s May 12 evening prep). Jamie invokes tool-foundation-sprint-brief to produce the one-page brief that locks scope and acts as the contract for the next two days.
Initiative Statement and Stakes
Brainshelf is a pre-seed B2C product for readers who want a better way to track what they have read and what they want to read next. The founding team is preparing for a friends-and-family raise in Q3 2026. Wrong product direction now could mean rebuilding the core experience post-raise, burning runway, and weakening the case to seed investors. The sprint exists because the team is divided on a load-bearing strategic call (individual collectors vs social readers) and needs to commit before MVP scoping.
Decision the Sprint Must Unlock
Should Brainshelf optimize first for individual collectors (private library tracking, personal recall, low social friction) or for social readers (community feeds, recommendations, book clubs, public profiles)?

Existing Inputs to Bring
- 22-interview synthesis (Riley). Themes already clustered; printed copies for Day 1 morning reference.
- One-page competitor cards (Riley). Goodreads, StoryGraph, Bookly, LibraryThing, compiled May 12 evening per readiness precondition.
- Discord notes on reader frustrations (Riley). Anonymized from her 12k-member book-blogger network.
- Pre-seed pitch deck draft (Jamie). Context only, not for input.
- Brand and visual sketches (Alex). For Day 1 PM differentiation context only.
Success Criteria
The sprint is successful if:
- By end of Day 2, the team ratifies a single Founding Hypothesis using the canonical “If we help X solve Y with Z…” template.
- The Hypothesis is specific enough to translate into a Design Sprint challenge.
- The Hypothesis Scorecard identifies the highest-risk assumption (the one the Design Sprint should test first).
- The team has a documented backup plan (the runner-up approach) if the top bet invalidates.
The sprint is unsuccessful if any of the above is missing or if the team ratifies a hypothesis that is structurally too vague to test.
Readiness Reaffirmation
The Go verdict from tool-foundation-sprint-readiness (2026-05-12) remains in effect.
- Decider availability still confirmed for both days (Jamie).
- Preconditions closed: Riley completed the competitor one-pagers on the evening of May 12 as planned.
- No new risk factors have surfaced.
- Conditional Go yellow flag (competitor research) is now closed.
Decider Checkpoint
Decider sign-off required before Day 1 begins.
- Jamie confirms scope: a single Founding Hypothesis is the deliverable.
- Jamie confirms team and attendance windows.
- Jamie confirms success criteria (testable hypothesis ratified by end of Day 2 with scorecard and backup plan).
- Jamie acknowledges that the team will NOT preserve both individual-collector and social-reader paths at the end of Day 2.
- Jamie commits to attending the Day 2 closing session.
