Do Diligence is a filing-first public-company research workspace for capital-markets and investment-banking professionals, operated by Vector Advisory Partners. Search covered issuers, screen securities, inspect dated SEC disclosures, and trace professional relationships to their filing sources. Available workflows include: • Overview, issuer search, and advanced screening with notice/event evidence date windows • Source-dated issuer Top Sheets with company overview and key data • Company profiles, financial statements, filings, filing events, and risk evidence • SEC-reported ownership and potential-common-stock instruments • Cap Table and RTO Payoff worksheets, warrant detail, and explicitly labeled local scenarios • Supported CSV exports and a two-tab Excel capitalization export • ECM Opportunity Radar, Daily Changes, and Registration Monitor • Advisor directory, firm profiles, professional contacts, and relationship intelligence • Exchange and OTC market-tier filters • Device-local saved screens and data-update status • Direct links to cited SEC accessions The Research Guide lists the available functionality and limitations. Research coverage varies by issuer and date. Missing inputs and incomplete capitalization remain clearly labeled; a displayed worksheet is not a verified complete or fully diluted cap table. Third-party market quotes, price-derived market values, historical market analytics, and real-time quotes are not provided in this release. Do Diligence provides preliminary research support, not legal, accounting, investment, or exchange-compliance advice. It does not execute trades or accept funds. Check cited filings before relying on any material fact. Version 1.1 is free to download and use, with no end-user account or access code required. There are no purchases or subscriptions.
