When I was little, my favorite thing to do was head out to the hills and play with mud.
Mixing different types of mud gave me different textures, weights, and reactions.
Honestly, I didn’t care much about the science behind it, I just wanted to see what would happen if I did this or that. Then I’d use whatever I learned to make weird little creations.
To me, it wasn’t “mud”，it was material.
Readily available, right there in the environment.
That’s how Beyz AI started, a tool I originally created just to help a friend prep for interviews.
It ended up in an accelerator, closed seed round funding, and attracted 230K+ users from over 49 countries.
Back then, the things I was molding were models, strategies, user behaviors, and sometimes, just the right sentence to help someone survive one more interview round.

Over the years, the things I molded have changed quite a bit.
From mud, wood... to website used by hundreds of thousands of users.
But what hasn’t changed is my curiosity for new “materials” as they emerge—new tools, technologies, or ideas—and my urge to shape them into something no one’s seen before.
Just like back then, I’m not chasing theory. I’m chasing possibility.
What can it do?
What can it become?
And how can I use it in the next thing I make?
But it’s not just about building. I also like to think about why we build things at all.
I’ve written articles on topics like the next wave of not-so-glamorous consumer AI, or why some users actually prefer “ugly” interfaces. Writing, for me, is like working with invisible materials—trying to stack them into something that makes people go, “Huh. That kind of makes sense.”

And then, there’s the fun stuff.
Like modeling a car seat just because I was curious.
Or turning an origami crane into a working light switch.
They don’t always have a big purpose—but when I’m working on them, it feels like I’m right back on that muddy hill again.

Designer, Writer, Builder
Hi, I'm Robert Sheng
All these different materials, shapes, and rhythms—they’ve slowly come together into what I do now.
Part designer, part writer, part builder.
But mostly?
Still that kid who hasn’t finished playing with mud.
