Hackathons—participatory gatherings in which people with various backgrounds and experiences come together to address a challenge or create something new in a limited period of time—have become an important part of today’s technological, social, and business landscapes. They originated in IT and have since spread into other fields including medicine, law, biology, environment, education, and civic engagement. How and why can hackathons drive innovation? How can they challenge the status quo? What role can they play in an organization’s strategy? Under what conditions are hackathons most effective, and what are their limitations?

Maciej Ryś—a hackathon leader and scholar with extensive experience in the field—offers a step-by-step guide to organizing successful hackathons and understanding their dynamics. He examines the evolution of hackathons from niche programming marathons to versatile platforms fostering technological advancements, entrepreneurial ventures, and social change. Drawing on extensive research, including observations and interviews from dozens of events worldwide, this book provides data-driven insights into the hackathon ecosystem. Ryś shares practical lessons for organizers, participants, and mentors ranging from planning to inclusivity and sustaining momentum afterward, emphasizing both individual and group levels. Readers will learn how to build better hackathons that attract more participants, and they will gain a deeper understanding of the dynamics of innovation. For both hackathon veterans and those new to the field, Sparks for Innovation helps readers develop new skills, discover new possibilities, and achieve new breakthroughs.
