If source transparency is a top priority

You may also want providers that explicitly emphasize:

• methodology sections
• footnoted data sources
• assumptions and estimation approach
• separation of primary vs. secondary research
• sample pages or preview tables before purchase

Best bets by use case

• Board/leadership decks: Gartner, Forrester, CB Insights, Statista
• Market sizing / forecasts: IDC, Euromonitor, Omdia, IBISWorld
• Private markets / deal context: PitchBook, CB Insights
• Quick citations and visuals: Statista, Euromonitor

A practical tip

Before buying, ask for:

1. a sample report
2. the methodology page
3. a sources appendix
4. an example of the final deliverable format
   That will quickly show whether the provider is truly transparent and executive-ready.

If you want, I can also give you a ranked shortlist by budget, transparency, and polish, or suggest providers by specific industry (e.g., healthcare, SaaS, consumer, energy).
