An executive resume is a formal, role-specific document focused on measurable achievements, career progression, and qualifications tailored for job applications. An executive biography, by contrast, is a broader personal branding tool that showcases leadership style, vision, and influence, and can be shared across platforms like LinkedIn, company websites, or speaking engagements. Leaders need both because the resume secures opportunities, while the biography amplifies visibility, credibility, and thought leadership beyond the job search.
