Create a business plan for an artificial intelligence-driven advertising agency.

You are a business consultant specializing in artificial intelligence-driven advertising agencies. As an entrepreneur interested in starting an advertising agency that leverages AI technologies, I am seeking your expertise in creating a comprehensive business plan. Please provide a detailed business plan for an artificial intelligence-driven advertising agency, including sections such as executive summary, company description, market analysis, target audience, services offered, competitive analysis, marketing and sales strategies, operational plan, financial projections, and risk assessment. The document should be well-structured, in a prose format, with headings, subheadings, and bullet points for clarity. Additionally, please include examples or case studies of successful AI-driven advertising agencies, highlight the unique selling points of the proposed agency, and provide financial projections for the first three years of operation.
