Entity resolution is the process of determining when different records refer to the same real-world entity — for example, linking a fund's many name variants, legal entities, and CIKs to one identity — so data can be joined reliably.
Real-world data is full of the same thing recorded inconsistently: "Berkshire Hathaway," "BERKSHIRE HATHAWAY INC," multiple CIKs, several CUSIPs per issuer. Entity resolution reconciles these into a single canonical identity so positions and filings can be aggregated correctly.
It is unglamorous, hard, and exactly where the durable value sits — clean identifiers are what let you ask one question across messy sources and get a correct answer.
Rolling three subsidiary CIKs and a dozen CUSIPs up to one "Berkshire Hathaway" identity so its true position in a stock is counted once.
Entity resolution is Arkolith's core labor — the moat is the acquisition + resolution work, not access to public filings everyone can already download.
Arkolith turns this into live, sourced data your agent can query — SEC filings, insider activity, and market data behind one key, every datapoint traceable to its origin.
