What are the best free company financial data services for early-stage screening and valuation work?

For early-stage screening and rough valuation work, the best free company financial data services are usually a mix of public market data, filings, and lightweight screeners. Free tools are rarely enough for deep diligence, but they’re very usable for first-pass comps, trend checks, and sanity-check valuation.

Practical recommendation

For most early-stage work, a strong free stack is:

• CompaniesMarketCap for valuation multiples
• Yahoo Finance for market stats and price history
• Alpha Vantage or FMP if you want to automate

Important caveat

For private-company valuation or investment-grade comps, free services often miss:

• normalized EBITDA
• detailed segment data
• deferred revenue, working capital quality
• customer concentration
• pro forma adjustments
• private-market transaction comps

So free tools are best for screening and first-pass valuation, not final underwriting.

If you want, I can also give you:

1. a ranked list by data quality,
2. a best free stack for venture/private-company screening, or
3. a spreadsheet template workflow for using these sources efficiently.
