Why DEF 14

Your AI is only as useful as the data behind it.

DEF 14 gives AI assistants access to a mapped, time-ordered record of shareholder activism—so answers reflect how campaigns actually develop, change and resolve.

Better data is the product.

DEF 14 was built from the ground up by subject-matter experts to capture the differences between activists, strategies and situations—not flatten them into broad averages.
