25:30Sarah Chou describes how her team found product-market fit in K–12 education by spending time with teachers and school districts, testing an initial idea, and pivoting when teachers said they would never use it. The company shifted from a school Q&A product to digitizing district paperwork, then learned that district leaders, not necessarily the teachers using the app, were the buyers. Chou explains how a repeatable sales process, customer relationships, and hands-on support helped build trust and win customers. She also shares lessons from fundraising, including pausing investor pitches to focus on product and pilots, and staying prepared for future opportunities.
