Rupesh Kumar Shah started his educational technology startup InOpen in 2009 while he was 23 years old. InOpen develops high-quality academic content for computer science education and provides solutions to over 200 schools, reaching 500,000 students. The startup has faced many challenges common to young companies, such as delayed revenue, cash flow issues, and difficulties with assumptions about customers, partnerships, and operations. Shah has learned that passion and perseverance are key to success as an entrepreneur, and that problems diminish with time if one remains focused on their goals and fundamentals.
