A manufacturing connection for founders building across borders
Jimhang Capital works with founders across Hong Kong, the Guangdong–Hong Kong–Macao Greater Bay Area and international markets at the angel and seed stages. Our ambition is to become a Greater Bay Area counterpart to Y Combinator: a place where exceptional founders can connect early-stage support with the resources needed to build ambitious companies.
For Silicon Valley and global hardware teams, that includes helping define manufacturing needs and introducing relevant Greater Bay Area smart-factory and supply-chain contacts. Bring the product you are building and the problem slowing you down. Jimhang is independent of, and not affiliated with, Y Combinator.
Turn a large ambition into the next piece of evidence
YC's Hard Tech Companies, Then and Now describes how ambitious projects can begin with an achievable first step whose results support the next. Our application of that idea is simple: define what the next build must prove.
A robotics founder might need to test one joint under repeated use, or find a partner who can assemble the current design consistently. Those are different problems. A clear question makes it easier to identify the relevant engineering work, discuss suppliers and judge whether the next step has helped.
A working brief from prototype to scale
Use these five stages to frame the discussion, starting wherever your team is today. This is a proposed working framework; the support and scope are agreed for each project. Qualified engineering teams and manufacturing partners make the technical decisions.
| Stage | Bring to the discussion | Working output |
|---|---|---|
| Prototype | Demo, intended user, validated functions, open problems | Prototype brief: capability to prove, success criteria, owner |
| Manufacturing readiness | Available drawings, BOM version, target cost, initial quantity | Gap brief: required engineering work, assumptions, owners |
| Supplier introduction | Required capabilities, shareable files, sample needs, budget | Introduction brief: questions for prospective partners and comparable quotation scope |
| Pilot | Agreed revision, quantity, test method, acceptance criteria | Pilot record: results, issues, change owners, conditions for another build |
| Scale | Pilot results, customer demand, available funding, order expectations | Production brief: quantities, cost assumptions, delivery milestones, review date |
Make the first introduction about a specific build
Imagine a Silicon Valley team developing a desktop AI device. Its demo works, but enclosure assembly, heat management and initial production costs remain unresolved. A useful opening brief explains who tested the device, which limitation affected their experience, how many units the team wants to build and which problem a partner should address. This is an illustration, not a Jimhang client case study.
Jimhang can help clarify that brief and connect the team with relevant resources for further discussion. The founders and the actual partners agree on manufacturing, quality control, pricing and delivery. Keeping a record of each revision gives the next engineer or partner a useful starting point.
Bring your prototype, customer evidence and next build problem
We particularly welcome AI hardware, robotics and smart-device teams with a prototype, customer evidence and a clear manufacturing question. Exceptional technical teams earlier in their journey are welcome too: describe the breakthrough, the experiments completed and the milestone you want to reach next.
Email justin@jimscapital.cn with the subject Hardware × Greater Bay Area | [Company]. Include a short introduction and a shareable demo or pitch deck. Tell us where your team is based, who needs the product, what already works and what help you want from the Greater Bay Area. A clear one-page brief is enough to begin.
Leave with a concrete work product
- Company, founders, location and engineering contact.
- One-sentence product description, intended users and customer evidence.
- Shareable demo, prototype status and technical milestone.
- The most important build problem and the resources you want to meet.
- Initial quantity, target cost, budget and timing; label estimates as estimates.
