| 1 | 6.0 | Leap-second transition testing for critical infrastructureTime-fault injection and audit tooling that lets telecom, power and finance timing teams prove their systems survive the end of leap seconds. | Venture | DevTools | 6 | 6 | 7 | 6 | 5 | 6 |

| 6.4 | Firmware decompilation exposure audits for hardware makers | Quoted the discussion instead of paraphrasing. |
| 5.9 | Local HealthKit bridge for Withings devices | The red team found a fatal weakness. |
| 5.4 | Driver rescue service for orphaned hardware | Multiple credible demonstrations of AI-assisted driver resurrection plus paying refurbishers sitting on stranded hardware make the demand real, and no commercial entity offers signed, maintained drivers — but per-device bespoke kernel work with signing/notarization liability is a consultancy, not a |
| 4.8 | Self-hosted runtime for vibecoded personal apps | The red team found a fatal weakness. |
| 4.6 | Crawler enforcement and evidence layer for publishers | Cloudflare (AI Audit) and DataDome are already shipping crawler identification and blocking as fast-follow features, and the differentiated bit — detecting consent-scraping via fake registered accounts plus litigation-grade evidence trails — is both technically brutal and something indie publishers |

| 4.4 | Real-versus-bot traffic analytics for small sites | Near-duplicate of the recently published scraper-driven cloud bill guard for small sites — both sell small site owners per-crawler identification and bandwidth-cost quantification. |
| 4.1 | Homelab recovery and handover kit for families | Two people's worries dressed as a market: the actual need is solved by a password manager's emergency access plus a written doc, and hobbyist self-hosters are among the least willing-to-pay buyers alive. |
| 3.8 | Verified directory of subscription-free health devices | A few HN commenters shopping for scales is not a market: the named buyer pays nothing (affiliate pennies only), Wirecutter plus Reddit already cover this informally, and the 'continuously re-tested' moat is unpaid labor with no revenue engine attached. |
| 3.8 | Maintained tested blueprints for homelab services | Free, good-enough app-store platforms (CasaOS, Umbrel, Yunohost) and Unraid already serve this exact audience, and the people who refuse those ecosystems are precisely the tinkerers who will never pay $79/yr for someone else's playbooks. |
