What you're actually getting in your inbox.

a

Researched, not manifested.

Every gap passes a six-check test before it ships. Pain documented, demand quantified, build scoped, wedge real, path to first dollar, gap unfilled. We publish the receipts.

b

Buildable in a weekend.

Every issue is stamped Weekend, Week, or Month. The estimate is honest. Most are weekends, because most worthwhile gaps are.

c

Build kit, not just an idea.

PRD, design spec, tech spec, ten ordered Claude Code prompts, starter dataset. From issue to first commit in the same hour.
