Requests for Startups (RFS) is hand-curated weekly and was inspired by YC.
e.g. "Hotel Tonight of Local" (Hunter Walk)
e.g. "I believe more recommendation/content experiences should be focus on constraining the options and making the recommendations immediately actionable. If I want dinner, don't tell me 50 restaurants with ratings, etc. Show me three that you 'know' I'll like and make a table bookable from the app." (Hunter Walk)
