Platform: Injection-molded product + e-commerce
Employer: 423 engaged ideas (own product)
Timeline: 12 months, May 2003–May 2004
Rock bottom became launchpad – through product craftsmanship
Four years in fintech. Zero portfolio pieces. Every project under NDA. I built PIT GREEN to prove I could design, develop, and ship. 423,000 units sold, 4 design awards, MOMA placement. From desperation to global product.
Core shift: From zero proof to 423k units – through end-to-end product thinking.

How we solved problems
Three challenges, three breakthroughs
The problem wasn't skills. It was proof.
After four years designing finance apps, I had zero portfolio. NDAs blocked everything. I couldn't show capability – only claim it. Clients want evidence. I had none. Built PIT GREEN instead – a miniature golf product capturing real golf mechanics. Focused on interaction first, form second. 3D-printed prototypes. Tested with friends. Documented everything. Research. Engineering. Manufacturing. Marketing.
The product became the portfolio. When you can't show work, make work.
Injection molding doesn't forgive. We caught flaws early.
Tiny design errors multiply across thousands of units. Early prototypes showed issues: golfer posture looked wrong, parting lines cut through details, structural weak points appeared. We ran zero-series production – pre-mass-manufacturing test runs. Engineers joked about giving the golfer a "digital chiropractor appointment."
Final result: zero major defects across 423k units. Mold thoroughness saved costs – fewer rejects, faster cycles. Precision prevents problems.
Zero-Series Validation: Multiple test batches → Real-world testing (drops, UV, repeated use) → Mass production only when perfect
We planned for toy collectors. Women bought 60%.
Market Surprise: Expected: Golf enthusiasts Reality: 60% women, gift market, design collectors
First edition sold faster than expected. 60% buyers were women – surprising for a "golf" product. Street artists and toy collectors became evangelists. Shared PIT GREEN at parties. Surveyed buyers: quirky design, conversation starter, portable fun. One collector: "The lovechild of miniature golf and a design museum piece." We leaned in. Positioned as design object, not toy. Secured MOMA Museum Shops (New York, Tokyo). Word-of-mouth beat advertising. When your product finds its people, follow them.
Feel the swing
Functional Prototyping
The prototyping phase validated interaction mechanics before aesthetic decisions. 3D-printed prototypes tested ergonomics, ball trajectory, and physics. Multiple iterations refined form factor based on user feedback. Physical models bridged conceptual design and manufacturing – ensuring functional requirements matched user expectations.
Engineering precision
Injection molding optimization
Mold engineering required precision. Golfer posture adjustments. Parting line placement debates. Structural reinforcement. Engineers joked about "digital chiropractor appointments" and "hairstyle concerns" – but these details mattered. Technical challenges kept the team laughing while maintaining rigor.
Zero-Serie validation
We call it Zero-Serie
Zero-Serie represents the initial small production run before mass manufacturing. Pre-production units test processes, verify quality, identify issues. Final validation step between prototype and mass production. Critical for catching errors before scaling.
Early adoption
1st Edition – for the advocates
First market version resonated with early adopters – toy collectors, gaming enthusiasts, street art scene. 60% female buyers proved good design transcends gender marketing. Early adopters became ambassadors. Quirky charm made it a conversation starter. Office break rooms. Backyard barbecues. Social gatherings.
One collector described it as "the lovechild of miniature golf and a design museum piece" – capturing the balance between playfulness and sophisticated design. This proved prophetic when PIT GREEN found its way into MOMA Museum Shops (New York, Tokyo), bridging playful products and design artifacts.
Global reach
2nd Edition – ready for scale
Key Learnings
What this project taught me
Building a product proves more than showing work
No portfolio? NDAs blocked everything? The pain: how to prove capability without evidence. What worked: building PIT GREEN from scratch and documenting the entire process – research, engineering, manufacturing, marketing. Clients saw end-to-end thinking. The product became proof.
Co-creation accelerates beyond solo capability
Friends shared my design passion. Their feedback, energy, skills elevated the product. The pain: balancing vision with diverse perspectives. What saved me: shared passion created alignment. Shared vision + diverse skills = compounded impact. Collaboration replaced isolation.
Markets reveal themselves through early adopters
Expected golf enthusiasts. Got 60% women, gift market, design collectors. The pain: our assumptions were wrong. What helped: listening to actual buyers. Surveying why they bought. Repositioning as design object, not toy. MOMA placement validated the market we accidentally found.
Why this still matters
Designers can build businesses, not just artifacts
In 2003, independent designers rarely brought products to market. Manufacturing was expensive. Distribution gatekept. E-commerce nascent. PIT GREEN proved vision, co-creation, and resilience overcome barriers. 423,000 units sold. 4 design awards. MOMA placement. But the real impact? Proving to myself – and future clients – I could take ideas from concept to global market. When you can't show work, make work that speaks.
