◇ MANIFESTO

Who Am I?

I'm Tibo, 36, French, living in Phuket, Thailand. I run a YouTube channel called Tibo Denz where I challenge myself to learn completely new skills and build things I have no business building. The channel is the honest, unfiltered version, including the parts where it all goes wrong.

I'm also a developer and entrepreneur. I consult for US companies and run Devmystify, an AI and dev education brand. But this channel is purely about building things and challenging myself.

If you've ever wondered what I'm actually doing with a 3D-printed Iron Man suit and a five-month diet, here's the honest version.

It started with a deathbed vision

One day I saw myself on my deathbed, surrounded by family, asking what I'd regret. Only one thing came up: I'd been saying I'd get a six-pack since I was a teenager and never made it stick. Not relationships, not work, not the projects I never built. Just that one body I was supposed to forge.

YouTube turned out to be my finishing engine

Then I noticed something weird. I have ADHD, I never finish anything, and yet I was finishing a video every two weeks, like clockwork.

Each video is basically a quest: pick a thing, commit on camera, ship it. That shape works on my brain. So on January 16th, I asked: what if I pointed the same engine at the one thing I've never solved? Next morning I shot the announcement. By the end of that week I was tracking calories, macros, hitting the gym. Haven't stopped since.

I'm still figuring out why public works

I don't fully know why doing something for a video makes it easier. What I know is the data: anything I commit to on camera, I finish. Anything I commit to privately, I don't. Public accountability is the secret sauce.

Why “Iron Man suit” specifically

The suit is the proof. If I lose the weight but the suit isn't ready, I just lost weight. If I build the suit but I don't fit in it, I have a $1,500 plastic statue mocking me from the workshop forever. Both have to actually happen.

I've wanted to build a full Iron Man suit since I got my first 3D printer three years ago. Add the six-pack I've been chasing since I was a teenager, and you've got two long-standing dreams stapled together with a public deadline. Very little downside if I fail. Massive upside if I succeed.

Honestly, at this point I'm realizing I just enjoy challenges that are hard, no matter the type (food, workouts, builds). My mom asked me last week if I was a masochist. I'm still thinking about it.

What happens on the other side

When I fit in the suit, the next arc opens: putting on muscle for another superhero. This opens doors for me. After that, more challenges I can't predict yet. That's the game I'm actually playing.

What I want from you

My favourite part of doing this is when people tell me my challenges helped them start learning or doing something of their own. That's absolutely amazing, and it's basically the whole point.

I'm just trying to be entertaining, and to show that anyone can do anything, if you wrap it in a quest with rules and rewards. Same as a WoW quest. Same as a video. Same engine.

If watching me try to pull this off makes you start your own dumb little quest, that's the whole thing landing.
