Frequently Asked Questions about Bigideasdb

Does BigIdeasDB pull complaints from Reddit, or do I have to scrape Reddit myself?

BigIdeasDB has already indexed complaints from Reddit along with G2, Capterra, Upwork, and app stores, so you don't need to scrape anything yourself. The platform also includes an MCP server as a Reddit API alternative if you want to build your own research workflows.

Do the revenue estimates come with a breakdown of how they're calculated?

BigIdeasDB provides revenue estimates for each idea, though the platform does not specify the methodology behind those calculations. Check their site or contact them directly if you need to understand how they arrive at specific numbers before making a build decision.

What's included in the step-by-step build guides?

Each validated idea comes with a step-by-step build guide, and the platform uses an 8-stage AI founder flow called BuildGuide to walk you through the process. The exact scope of each stage is not detailed, so review the guides on their free plan to see if they cover your specific workflow.

Can I use BigIdeasDB to validate an idea I already have, or is it only for discovering new ones?

BigIdeasDB is built around discovering ideas from complaint data, but you can use its search filters, competition gap analysis, and revenue intelligence to research existing ideas before you build. Whether that validation layer is as deep as their discovery process is not specified.
