The SEC is conducting market research to identify sources for a Financial Data Sources subscription, preferring a Commercial Off-The-Shelf (COTS) product requiring no development. Interested companies must submit a cover letter, a capability description addressing the draft requirements, completed questionnaire and requirement matrix checklists, and a price estimate for one base and four option years. The SEC may contact respondents for further information, including one-on-one meetings and demos. This is a sources sought notice for planning purposes only, not a request for proposals, and no contract award will result from this announcement. Responses become government property, and proprietary information must be clearly marked to protect it from disclosure.
