Frequently asked questions

What is Nicheloom?

Nicheloom tracks 33,000+ product launches from Y Combinator, Product Hunt, Hacker News, and GitHub Trending, groups them into themes, and scores each theme on momentum vs. crowding -- so you can see what's gaining traction before it's crowded.

Is Nicheloom free to use?

Yes. Every page -- Themes, Gaps, Matrix, Search, and the rest -- is free to browse.

Where does the data come from?

Public launch listings from Y Combinator, Product Hunt, Hacker News, and GitHub Trending. It's supply-side data -- what builders shipped and how much attention it got -- not a measure of real demand, willingness to pay, or market size.

How often is the data updated?

Twice daily. A nightly pipeline ingests new launches and refreshes every score on the site.

What does the opportunity score mean?

A blend of four signals: attention (how much traction a theme's launches got), low crowding (how few competitors are active), momentum (growth vs. the prior window), and low concentration (varied approaches, not copies). Higher means more worth a closer look.

What's a gap on the Gaps page?

A vertical x function cell that's nearly empty relative to how busy its row or column is everywhere else -- a quiet cell inside an otherwise active neighborhood, not just a quiet category in isolation.

What does vibe-codeable mean?

Our own classification of whether a launch looks buildable with an AI coding tool (Cursor, Bolt.new, v0, and similar) in a weekend, based on its apparent scope and complexity -- not a guarantee, a starting signal.

Does a high opportunity score guarantee a good business?

No. It's a shortlist signal -- a theme worth investigating further, not a validated business model. Every view on Nicheloom is a starting point, never a verdict.

How do I advertise on Nicheloom?

Visit the Advertise page in the site footer -- sponsor slots are self-serve and rotate across every page.

Is there a newsletter?

Yes -- a free daily digest of the day's top launches, news, and a weekly opportunity spotlight. Sign up from the Newsletter page.
