AI deal screening uses artificial intelligence to analyze business acquisition documents (CIMs, financial summaries, and broker listings) and produce a scored deal card with red flags, industry research, and a recommendation in minutes instead of the hours it takes manually.
Turnstone extracts financial data from your uploaded document, scores the deal across 15 qualitative factors grouped into three pillars (Revenue Quality, Operating Model, and Return Levers), flags risks like customer concentration or declining revenue, and researches the industry, all automatically in about 5 minutes.
Most deals are fully screened in 2 to 5 minutes. PDF uploads run faster (2–3 min) while URL screens take slightly longer (3–5 min) because they include live web research. Manual screening of the same deal typically takes 45 minutes to an hour.
PDFs (CIMs, teasers, broker packages), Excel spreadsheets, Word documents, CSV files, and images. You can also paste a listing URL from BizBuySell, Flippa, Axial, or any broker website and Turnstone will extract the data directly.
A free Introductory tier with 7 lifetime deal screens, no credit card required. The Pro plan starts at $9.99/month plus $0.50 per screen for the first 3 months, then $24.99/month plus $0.50 per screen. Most users screen 10–20 deals per month.
Yes. Turnstone uses row-level security in PostgreSQL so each user's data is isolated at the database level. Authentication is handled by Auth0, documents are stored in encrypted private buckets, and AI processing happens through Anthropic's API which does not train on your data. See our security practices page for full details.
Anyone evaluating a business to buy: search fund entrepreneurs screening 50+ deals/mo, independent sponsors reviewing broker deal flow, first-time buyers on BizBuySell or Flippa, and M&A advisors managing client pipelines. If you're reading CIMs, Turnstone saves you time.
Manual screening means reading a 30-page CIM, building a spreadsheet, researching the industry, and forming a view, typically 45 minutes per deal. Turnstone automates all of this with consistent methodology across every deal in your pipeline.
Every week we screen a real, publicly listed business on Turnstone Insights. See exactly how the scoring works, where the red flags hide, and whether we'd recommend advancing to diligence — before you sign up.
