Why should students

participate in

start-up project?

Start-ups are well known for their relentless execution of ideas, which demands swift decision-making, efficient idea-to-product protocols, and a never-give-up attitude. Throughout the SPRINT PROGRAM, students are consistently exposed to these fundamental traits of start-ups.

Fast Decision Making

Throughout the SPRINT PROGRAM, students gain an understanding of the significance of making informed decisions grounded in real-world customer data. Along the way, they embrace a start-up axiom: “the only valid ideas are those that have been tested against the realities of the real world.”

Idea to Product

After the decision-making process, students delve into various methodologies and tools to execute their ideas. They discover that there is no one-size-fits-all approach, and failures offer invaluable insights into the authenticity of the product they are creating.

Not Giving Up

Through the SPRINT PROGRAM, students grasp the significance of discovering their genuine passions. This cultivates a robust mental resilience to overcome external challenges and helps them truly comprehend the value of perseverance and “not giving up.”
