The Beginning
The Beginning

Started as a student developer with curiosity and no roadmap. The first hackathon wasn't about winning—it was about discovering that technology could solve real problems and change lives. That single experience sparked everything that followed.

The Setbacks
The Setbacks

Three consecutive hackathon losses between 2019 and 2020. Every defeat exposed a weakness in execution, teamwork, problem selection, or storytelling. Instead of walking away, we chose to learn from every mistake and keep showing up.

The Framework
The Framework

Winning teams weren't lucky,they followed patterns. We studied successful submissions, analyzed judging criteria, refined our approach, and built a repeatable framework for innovation, pitching, and execution. Failure became a system for improvement.

The Breakthrough
The Breakthrough

The turning point came at Smart India Hackathon 2022. Against some of the best engineering teams in the country, we built a cybersecurity solution for DRDO and became SIH World Champions. What followed was a run of seven championship victories and national recognition.

Icon
The Movement

When we needed guidance, there was none. So we built what we wished existed—content, mentorship, webinars, playbooks, and communities dedicated to hackathons and innovation. From India's first hackathon e-book to 100+ mentorship sessions and a 250,000+ learner ecosystem, the mission became bigger than winning.

What they say

Awards measure recognition. Outcomes measure impact. These experiences come directly from the students, teams, and communities I've had the opportunity to work with.

Your mentorship didn't just help us win hackathons, it helped us grow into mentoring others as well. After your guidance, we went on to win 7+ more hackathons and it completely changed the way we approach problem statements and innovation. Truly grateful for your mentorship and support!

With his guidance, our team's productivity tripled. What began as a simple PPT turned into a killer presentation. He made us do it simply by asking the right questions, one at a time. That simple tip changed everything. A true game-changer.

Gamaliel was completely honest throughout the session and cleared every doubt in a way we all could understand. He pointed out how critical each mistake can be. Humble, honest, and mostly graceful. Loved it, thanks Gamaliel!

I attended a PPT phase session where sir was so friendly and made me comfortable. It gave me more confidence, helped me improve my presentation, and I got a lot of useful information. Thank you so much.

Sir gave us the best insights possible. We would have never known our weak points if we never talked with him. He gave us a complete picture of the SIH Finals in a very friendly, helpful and honest way. My team and I really had a great time with sir.

The suggestion you shared in your video for the finale really helped me. I showed only 30% of my prototype in the first review instead of the entire thing. I took the feedback from the juries, applied the improvements for the second review, and from that point onward everything went really well!

The e-book is amazing! Having this book got me into the finals of GDG TechSprint Hackathon at my university. The Hunter Hackathon Assistant GPT in the book is great for idea research. Trust me it really helps in presentation, planning, and has everything you need to get selected. It's the best!
