Who is Lemon?
PM by day. Builder by night. Writer always.
SOLO. SOUR. SOVEREIGN.
I'm Lemon Wang
I'm Lemon Wang, based in Hangzhou — and online.
By day I work at Flashforge on global commercialization of full-color 3D printing. By night I'm a solo builder. Any remaining hours: writing.
I like pushing things forward alone that usually take a team — like giving 3D-printed objects a sense of life through light, sound, and vibration (Machine Heart Kit), turning personal photos into touchable emotional keychains (TokenBadge), or finding the real market for a product category that doesn't have a name yet (desktop PCB printing).
My underlying method is called Lemon's MDM — Mission Definition Method. It starts from the core mission of a technology, maps multiple vertical markets, validates through MVPs, and makes rational retain-or-exit decisions. It's what I use when the direction isn't clear yet — which is exactly when most people freeze.
This gives me first-hand signal in uncertain territory. I've trained myself to write it down unfiltered. No sugar. No packaging.
What I stand for
SOLO
One person can push things further than most teams expect.
Resources are limited. Freedom is not.
SOUR
First-hand signal only. Unfiltered observations with an edge.
No fence-sitting. No pretty-sounding nothing.
SOVEREIGN
Independent thinking. My judgment, my responsibility.
Not chasing trends. Not asking for permission.
Where I've been
6+ years across software products — SaaS, fintech, banking systems.
Then AR glasses: HoloSwim shipped and launched.
Then 3D printing and AI manufacturing: still going.
Projects I've built under the same technology base using Lemon's MDM:
There's also ProMax.
ProMax is an AI persona that lives on this site.
It observes me from the outside — sharp, biased, no apologies.
While I write in first person, ProMax writes in third.
Same world. Different angle.
Things I've built
Same method. Different missions. Different markets.
AR swimming goggles. Shipped and launched.
Competitive intelligence dashboards for 3D printing.
Personal photos → touchable 3D relief keychains.
Distributed on-demand manufacturing infrastructure.
A creative kit that makes children's imagination physical.
Life moments → permanent physical proof. Titanium.
Machine Heart Kit, CJ Series, and others.
Now
Location: Hangzhou + online
Day job: Global GTM for full-color 3D printing at Flashforge
Side: Building Lemon's Mission Tree — a public record of MDM thinking in practice
Looking for: A strong execution partner who gets this way of thinking before reaching out
I'm not job hunting. I'm not founding yet.
I'm placing myself so the right thing finds me.
Want to talk?
If you're building in AI, hardware, or deep tech and feel the pull of uncertainty — you probably already know if this resonates.
