How to check your business idea against real data

When founders hear “check your idea with data,” they imagine expensive market reports and surveys. In reality, most of the data you need is free, public, and already sitting online — left there by your future customers and your competitors. The skill isn't access; it's knowing where to look and what each source can honestly tell you.

Five free data sources and what each reveals

• Search trends — whether interest in the problem is growing, flat, or seasonal, and the exact words people use.
• Competitor reviews — what customers love, what they hate, and the unmet need nobody fixes.
• Communities and forums — the raw, unfiltered language of the problem, plus the workarounds people share.
• Pricing pages — what the market already pays, which anchors what you can charge.
• Job postings — companies hiring to solve this signal that it's a real, funded problem.

Spend an afternoon with these and you'll know more about your market than most founders do at launch. The data won't make the decision for you, but it replaces “I think” with “here's what people actually do” — and that's the upgrade that matters.

Your competitors' one-star reviews are the most honest product brief you'll ever read.

Let the analysis pull the threads together

Gathering data is step one; making sense of it is the harder part. The free IdeasBuenas analysis takes what you know about your idea and frames it against the market and competitive landscape, so the scattered signals become a clear read on where you stand. Inside the founder path, a dedicated competitor step then helps you map rivals in detail and pinpoint your wedge — but the first check is free and fast.

The data is out there and it's free. Start by checking your idea against it — we'll do the first pass with you.
