This public Follow surface is the human view. The Build surface lets your agent pull the same investors, holdings, and quarter-over-quarter changes through API or MCP.
Portfolios reconstructed from SEC EDGAR Form 13F filings (institutional managers with $100M+ in U.S.-listed securities), updated quarterly. The clone return is a simulation of the disclosed long book at the filing date (long equity only, total-return), not an audited fund return. Programmatic access via the Arkolith API & MCP server.
