About Expert Source Index

A buyer-education reference that helps investment firms, consultancies, and corporate teams source and evaluate expert networks and independent-consultant marketplaces, and understand how the category actually works.

Sourcing an expert network is high-stakes and low-transparency. Buyers face a maze of similar-sounding pitches with no consistent way to compare network size, compliance rigor, or engagement model. Expert Source Index exists to fix the first conversation: it turns each part of the category into a plain checklist of how it works, what to verify, and what to ask, then routes real sourcing requests toward qualified vendors.

Alongside the sourcing layer, we maintain a sourced reference to notable real vendors active in the space, so the vocabulary and the landscape are one click away.

Who runs it

Expert Source Index is published by KG LLC. It is buyer education, not an investment adviser, not a compliance consultant, and not a ranking or certification of any vendor. Contact us at hello@expertsourceindex.com.
