Hi, I'm Mary. I help teams cut BOM costs by 15–25%.

I'm a Shenzhen native and shipped American-made units to scale. I speak the languages of both sides (literally).

Mary Ma · Founder

I took part in shipping Corvus One. The fully autonomous platform for warehouse inventory management.

While hardware teams optimize and derisk technical feasibility,
I derisk cost, quality, and long-term supplier reliability early on
— it's insurance against costly future redesigns.

What is preventing you from shipping your hardware THIS quarter?

Let's see if there's a fit. 5 min call, no obligation.

To teams designing, prototyping, and shipping hardware in the US, EU, and Greater China — I can meet you where you are:

↓

Concept drawings

Initial prototypes

Early volume

Scaling production

Two ways to engage

I work in your BOM.

When

Your first units are built, but cost, minimum order quantity, quality, or vendor reliability have generated problems, or are starting to be a cause for concern on the next batch size.

What's the first step

Line-by-line BOM review to identify highest priority parts.

What Done Looks Like

Better parts in hand from a qualified supplier that you're confident committing to in growing volumes. The BOM is improved, whether that's on cost, quality, or order cadence.

I work on parts — whether they exist yet or not.

When

You're in early development — hardware architecture might not be locked in, but you're already running into questions about component quirks, lifecycle, or your design's manufacturability at scale.

What's the first step

Specs and constraints review to isolate dev blockers for parts.

What Done Looks Like

The primary blocker on the part is resolved — whether that's samples in hand, a reliable supplier that supports prototypes and volume, or a derisked sourcing plan for components at the end of its supported lifecycle.

Let's see if I can help unblock your hardware project.

I take confidentiality seriously. I'll aim to respond within 1 business day if there's a fit.
