The Business Association of Stanford Entrepreneurial Students (BASES) is a major entrepreneurship organization at Stanford University that has periodically run high school–focused programs and competitions, including pitch and innovation challenges for students interested in startups and business. These initiatives typically invite high school teams to develop a business idea, create a pitch deck or business plan, and present to judges connected to Stanford and the broader startup ecosystem. Opportunities for high school students with BASES vary by year and may include virtual or in‑person pitch events, mentorship, and workshops led by Stanford-affiliated entrepreneurs. Participants can gain experience in ideation, market research, and pitching, and top teams may receive recognition, feedback, or small prizes. Because programming changes, interested students should check the official BASES website and events pages each year for current high school competitions and application details.
