Medhansh Seth is a dynamic teenage entrepreneur, FICCI director, 4-time Rubik’s Cube state champion, and the visionary founder of AceCubing.com — one of India’s leading cubing education platforms. With over 150 competitive podiums and a Guinness World Record event, he has mentored 600+ students across the world. Beyond cubing, he’s an author, youth business leader, and startup enthusiast who has interned with top institutions, spearheaded Shark Tank-style events, and is currently penning a book based on conversations with global founders — all while excelling in high school. Most recently, he has been inducted into FICCI as one of its youngest directors and invited as a youth delegate to the India–Russia Business Forum, where national media houses such as CNBC, ANI, PTI, and CNN-News18 have featured his views on bilateral trade and India’s Gen Z entrepreneurial spirit.

I started AceCubing as a simple idea: take something I was really good at – the Rubik’s Cube – and use it to teach kids discipline, focus, and pattern-thinking.

What began with a few students turned into workshops, online batches, mosaics, events, and 600+ students. I learned how to send invoices, handle customers, fix a broken website, run ads that sometimes totally fail, and build a tiny brand that people actually remember.

Speedcubing sounds like a random niche, but it taught me almost everything about startups: repetition, feedback loops, small optimisations, data, and how to keep going when you’re stuck on the same problem for hours.

My “business education” didn’t start with a textbook. It started in the backseat of cars and in the corners of conference rooms.

I grew up tagging along with my dad to meetings, trade fairs, and factory visits. I watched him build a company from scratch – the long drives, the pressure, the small wins, the months when nothing seemed to move. Those trips made one thing very clear: entrepreneurship is not the glossy, 60-second reel version we see online. It’s exciting, yes, but it’s also confusing, political, tiring, and deeply personal.

By the time I was old enough to start my own thing, I already knew I didn’t want the “Instagram founder” life. I wanted to actually understand what I was signing up for.
