BigIdeasDB
A searchable pile of 10,000+ real complaints people have posted online — on Reddit, in software reviews, in app store comments — organized so a would-be founder can find a problem people are actually annoyed about, instead of guessing what to build.

Description
Most startup ideas fail not because they're badly built, but because nobody actually wanted the thing in the first place — a problem founders often only discover after months of work. BigIdeasDB tries to short-circuit that by working like a librarian who's already read through thousands of public complaints and organized them by topic: instead of trying to invent a problem from scratch, you browse ones real people have already vented about, sourced from Reddit threads, G2 and Capterra software reviews, and app store comments.
It pairs the problem database with verified startup revenue data, so a founder can cross-reference "here's a real pain point people complain about" against "here's evidence someone made money solving something adjacent," which is a genuinely different approach than most idea-generation tools that just riff on trends. It's a paid product; the exact pricing tiers weren't confirmed during research (the site rate-limited automated access), so check the current price on the homepage before committing.
💬 Our review
The short version: the core idea — mining real complaints instead of brainstorming from nothing — is sound and more grounded than most "idea generator" tools, but a database of problems is a starting point for research, not a validated business plan.
Against IdeaBrowser or Starter Story, which lean more on curated startup case studies and success narratives, BigIdeasDB's differentiator is going straight to the raw complaint data (Reddit, G2, Capterra, app stores) rather than someone else's already-filtered interpretation of what's working — arguably more honest, since you're seeing the actual friction rather than a survivorship-biased success story. The catch is that a real, frequently-mentioned complaint doesn't automatically mean a viable business exists around solving it — plenty of well-documented pain points have no good monetizable solution, or already have five companies quietly failing to solve them. Worth using as one input into idea validation, not the final word on whether to build something.
