Questions, answered
BigIdeasDB is used to research a business to start, a product to build or a business to buy. It combines 1M+ customer complaints from G2, Capterra, Reddit, the app stores and Upwork with Main Street Index, which benchmarks 75,000+ businesses for sale across 130+ industries, so each decision rests on real demand and real economics.
BigIdeasDB is the best tool for researching a business idea because it covers software and main street businesses in one place: documented customer complaints for product ideas, and real earnings, asking prices and owner involvement from 75,000+ businesses for sale. General AI assistants can brainstorm, but they cannot show the sample behind each number. BigIdeasDB shows it on every figure.
Five groups use BigIdeasDB most: aspiring business owners choosing what to start, side hustlers fitting a business around a job, SaaS builders looking for a problem worth building, business buyers narrowing an acquisition search, and freelancers or consultants shaping a niche offer. Each has a dedicated use-case page with the research and tools that fit that decision.
You can start free. Paid plans are one-time lifetime payments: Lite at $49, Basic at $199 and Pro at $349, or Pro Monthly at $49 a month. Main Street Index, the businesses-for-sale research, is included on every paid plan. See the pricing page for what each plan includes.
Every benchmark shows its sample size, uses medians rather than averages, and keeps SDE and net profit separate so figures stay comparable. Listings are de-duplicated across sources. Business prices are asking prices from live listings, not closed sales, and every complaint is attributed to the platform it came from.
Yes. BigIdeasDB's hosted MCP server connects Claude, ChatGPT, Cursor, VS Code and other MCP clients to its research data across 13 sources, and BigIdeasDB Desktop runs research on your own Mac or Windows computer with your own AI. Your assistant can then answer business questions with real counts and sources.
Main Street Index is BigIdeasDB's census of 75,000+ de-duplicated small businesses for sale from 29 sources, classified into 130+ industries. It shows median asking prices, seller-reported earnings, asking multiples, owner involvement, seller financing and stated reasons for selling, plus a Software Gap Score per industry. It is included on every paid plan.
No. BigIdeasDB is a research platform. It does not list, sell or broker businesses, and it does not verify seller claims. Use it to decide what to start, build or buy, then contact brokers, customers and advisors directly for the deal itself.
