Positioning
Out of Stealth (oos.kr) is a discovery directory for new products and services. Like Product Hunt, submit a product or service, browse, and collect reactions through upvotes and comments. Not limited to any one niche (it isn’t AI-only), a single discovery channel for otherwise scattered products and services.
The former AI prompt marketplace at oos.kr was split out and moved to BootSignal; oos.kr has now launched as a Product Hunt-style product & service discovery directory (live).
Cleanup (2026-07-01): the AI-tools comparison directory was removed entirely by operator decision (old URLs 301). Discovery (products, concepts, community) is the single core.
Company directory (2026-07-07): added a company directory benchmarked against the YC startup directory (ycombinator.com/companies). Filter companies by industry, region, and founding decade, and explore each company profile with its intro and flagship products. Starts from a statically curated seed of 40 companies (26 Korean, 14 global).
Problem and Solution
New products and services are scattered across channels and hard to discover. Out of Stealth presents products and services on one screen and gives visitors a discovery experience where they can browse and signal interest with upvotes and comments.
Current Status
- Status: Live. Approval-based submission (1 credit, operator review), read-only upvote counts, community board, concept showcase, company directory
- Stack: Astro + Firestore (named DB
ooskr), popular/latest sorting, ko / en / ja / zh-cn - Started: 2026-05, Launched: 2026-06
- Next: wire the crawl → AI-normalize auto-population into the discovery feed (
ooskrproducts) so discoverable products and services grow automatically, plus expanding the company-directory seed (a company/product submission flow is a follow-up)
