Who is Medhansh Seth?

I’m Medhansh Seth — an 18-year-old founder, author, athlete, and FICCI director from New Delhi.

I founded AceCubing to help students build focus, patience, discipline, and problem-solving skills through Rubik’s Cube training and mental sports. What began as my own journey as a competitive speedcuber has grown into a skill-based learning platform through which I have taught and mentored 600+ students across online courses, workshops, and school programs.

I am also the author of Surrogate Entrepreneur and the founder of Youth Cognitive Mission, a youth-led initiative focused on rebuilding attention, boredom tolerance, deep thinking, and offline cognitive habits in the screen-first generation.

My work sits at the intersection of entrepreneurship, education, focus, mental sports, and youth development — with one simple belief: young people do not lack potential; they need better systems to build skill, confidence, and original thinking.

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.
