A data-ranked list of business ideas: small businesses to start or buy, SaaS ideas and online business ideas, ranked by real earnings, prices and revenue. Sponsored by BigIdeasDB

Summary

bigideas-db/awesome-business-ideas is a curated, data-ranked reference for business opportunities, including small businesses to start or buy, SaaS and software ideas, online businesses, AI-agent ideas, and service businesses. It gives each idea a rank and one headline metric; the README says its larger scorecards contain prices, multiples, margins, opportunity scores, customer quotes, and build plans in BigIdeasDB.

What it is useful for

For software engineers, the most useful sections are “Markets full of operators, empty of software,” “Most crowded software markets,” and “Software ideas from real customer complaints.” These provide a way to compare potential domains before investing engineering time—for example, choosing between a vertical SaaS opportunity and an idea derived from recurring customer complaints. The README says the rankings draw on 46,000+ US businesses for sale, 8,000+ indie products with verified revenue, 17,000+ funded startups, 7,000+ AI-agent connectors, and 1M+ real customer complaints.

The small-business rankings provide acquisition context as well. The top 25 include chiropractic clinics at #1 with $200K in median annual owner earnings and 140+ listings, dental practices with $413K and 210+ listings, and pizzerias with $125K and 1,200+ listings. These numbers describe existing markets; they are not forecasts for a new product.

Several limitations are explicit. “Owner earnings” means seller discretionary earnings: profit plus the owner’s own pay. The 🧪 marker means fewer than 100 listings, so the result is indicative. Full asking prices, earnings multiples, margins, seller-financing rates, quotes, and build plans are available through BigIdeasDB. The list is sponsored and maintained by BigIdeasDB, so readers should account for that when assessing the source.

How engineers can use it

Start with the README’s Top 25 table and sector indexes, then use the SaaS and complaint-derived sections to form a shortlist. For each candidate, note the market, the evidence type behind it, and the headline metric. For acquisition ideas, the Buyer Fit Score combines earnings yield, affordability, margin, durability, supply, productivity, and seller financing. Open the relevant BigIdeasDB scorecard for the full financial and customer evidence before deciding whether to prototype or contact potential users.

No installation, CLI, API, or export workflow is documented in the supplied README, so there is no setup command to run. Treat the README as the research entry point and follow its links for deeper data. The README labels the data snapshot as October 2026, which is worth checking when assessing how current the figures are.
