I'm Krstic Lei — industrial designer and product development consultant based in Asia. With a background in industrial design from Zhaoqing University and Folkwang University of the Arts (Germany), I've spent years working at the intersection of design, engineering, and manufacturing.
I work primarily with international clients — Amazon sellers, hardware startups, and consumer brands — who need a reliable partner on the ground in Asia to manage the full product development cycle.
Consistent, detail-oriented follow-through — every round of samples came back with packaging and compliance details already double-checked, not left for us to catch.
Design iterations were fast and precise. Feedback from one round was fully addressed before the next sample arrived — no repeated back-and-forth.
When a compliance requirement changed mid-project, the product experience wasn't sacrificed to meet it — issues were caught and reworked on the spot instead of dragging into the next round.
Always knew exactly where a shipment stood — updates came without having to ask.
Ongoing support on a monthly basis. Best for brands that need a reliable partner throughout their product development cycle — from sourcing to production follow-up.
Fixed scope engagements structured in phases — sourcing, industrial design, R&D, sample production, production tracking, QC inspection, freight forwarding, and factory audit can each be hired on their own, or combined into a full concept-to-production cycle.
It depends on the product and the factory — there's no fixed number. We negotiate MOQ directly with suppliers as part of sourcing, and factor it into the factory selection from the start.
Usually within a month. More complex products — electronics in particular — can take longer depending on component sourcing and firmware iteration.
Yes. Services are split into independent phases — sourcing, industrial design, R&D, sample production, production tracking, QC inspection, freight forwarding, and factory audit — and each can be engaged on its own.
Ongoing monthly support is typically $500–$1,000/month depending on scope. Project-based work is priced and billed per phase instead, if that fits your needs better.
An NDA is signed before any project starts. Client ideas are never reused or shared.
Whether you have a rough concept or a detailed brief, I'm happy to discuss how we can work together to bring your product to market. No call required — describe your idea in writing and I'll reply within 12 hours.
