TheGrefg has 19 million YouTube subscribers, a Guinness World Record, and co-owns one of Spain's most prominent esports organisations. He is not easy to impress.
But when he spent a day at Tetr's India headquarters, walking the campus, sitting down with the founder, and stepping into a student mela while students were mid-term building real D2C businesses for their term assignment, something clearly shifted.
This is what that day looked like.
Before the mela, before the campus corridors, there was a conversation.
Grefg sat down with Pratham Mittal, and what could have been a founder's pitch became something more like an honest exchange. Pratham did not sell him the idea. He explained the thinking behind it. What it means to build an institution around doing rather than listening. The traditional model leaves such a wide gap between what students learn and what the world actually asks of them. And what it looks like when you close that gap completely, from day one.
For someone who built everything he has without a conventional roadmap, TheGrefg was not hearing something foreign. He was hearing something familiar, just applied to an entirely different scale and a much younger generation. By the time that conversation ended, he was not a guest being shown around. He was genuinely curious about what came next.

Tetr students were deep into building their own D2C brands from the ground up. The mela was their moment to take it public. They set up pop ups, put their products on display, and opened their doors to real customers walking by. It was loud and a little chaotic, the kind of energy that hits you before you fully understand what you are looking at. Every stall had a student behind it. Real customers walking by, real money changing hands, real conversations that could go either way.
The students did not hold back. Revenue numbers came up within minutes. Thousands of dollars, already generated, from businesses they had built themselves mid-term. One student took a rejection, barely flinched, and moved straight to the next person in line.
That was the moment. TheGrefg stopped talking and just took it in. Then said, plainly, that this is how education should actually feel.
He had one-on-one conversations with many of our students where he asked them about their days,what the schedule actually looks like, what they are doing when they are not at a stall or in a session. And what he heard was not what most people picture when they imagine student life. A student of ours told him how they build dropshipping businesses within 24 hours. Not pitching it, not planning it. Actually building it, end to end, in twenty-four hours. He refused to believe it!
Others talked about days that bleed into nights and nights that bleed back into days. Working around the clock, not because someone told them to, but because they were preparing for lives they imagined for themselves and thrived while doing it.
TheGrefg has built a career on discipline and output. He knows what it means to put in hours that most people would not. He was left in disbelief that these students might actually be working harder than he does.
Coming from him, that is not a small thing to say.
Grefg has spent years being the person others watch to learn something. What made this particular day unusual is that at some point, quietly and without announcement, that dynamic reversed.
He was the one watching. He was the one absorbing. Taking in a room full of people younger than most of his audience, already doing things his audience dreams about. And the thing that visibly stayed with him was not a number or a feature or a talking point. It was the feeling of a place full of people who are not waiting for the right moment to start, because for them, the starting part has already begun.
That is what the visit looked like from the inside. And it is worth seeing for yourself.
