“one sheet” in the speaker’s professional world is a single-page document that summarizes a speaker’s expertise, speaking topics, and key credentials, essentially acting as a quick overview to convince potential event organizers to hire them for speaking engagements; it’s like a brief resume highlighting their speaking abilities and value proposition. An “engagement speakers kit” refers to a collection of materials a speaker uses to showcase their expertise and capabilities, designed to attract potential clients or event organizers by highlighting their ability to deliver engaging and impactful presentations, typically including a bio, speaking topics, testimonials, headshots, and sometimes even video samples of past presentations; essentially a marketing tool to get booked for speaking engagements.
