The challenge

AuraSense AI needed to reduce unit costs from $140 to under $100 while scaling from prototype to 50,000 units for a global launch. Their sensor complexity required ISO-certified quality that smaller prototype shops couldn't guarantee.

Our solution

We utilized our U.S. + Shenzhen model, performing rapid NPI in Shenzhen for speed and ramping mass production in the same factory for cost optimization.

The Challenge: AuraSense AI, a Silicon Valley startup, developed a breakthrough heart-rate monitoring ring but hit a 'scaling wall.' Local US-based prototyping was costing them $140 per unit, far exceeding their target retail price point. To survive their Series A launch, they needed to scale to 50,000 units in under 4 months while maintaining medical-grade quality standards.

The Solution

Illuminious deployed our U.S. + Shenzhen model to provide both speed and scale. Key elements included:

  • Rapid NPI (Shenzhen): Completed 3 design iterations and DFM optimization in just 14 days.
  • Scale Production (Shenzhen): Ramped mass production on our own Shenzhen lines to leverage lower costs and one quality system.
  • Custom Test Jigs: Engineered automated optical and electrical test stations to validate sensitive biometric sensors at scale.

Measurable Results

$91
Target Unit Cost

A 35% reduction from initial prototype costs through optimized sourcing and Shenzhen manufacturing.

14
Weeks to Launch

Accelerated the production timeline by 50% compared to traditional Tier-1 contract manufacturers.

99.7%
First-Pass Yield

Consistent, high-quality output using automated testing protocols in our ISO 13485-certified lines.

How We Did It

1. DFM & Component Optimization (Week 1-2)

Our Shenzhen engineering team identified 4 component alternatives that reduced BOM cost by 18% without affecting sensor accuracy. Achieved DFM-ready status in 10 days.

2. Tooling & Batch Testing (Week 3-6)

Tooling was manufactured in Shenzhen and moved straight to the production floor. We ran a 500-unit pilot batch to validate the automated testing jigs and assembly SOPs.

3. Mass Production Ramp (Week 7-14)

Production scaled from 5,000 units per week to 15,000 units per week. Our Shenzhen team managed 24/7 shifts to meet the critical launch date.

"Illuminious solved our biggest nightmare: how to go from a high-cost prototype to a profitable, high-volume product. Their U.S. team and their own factory in Shenzhen gave us the speed we needed and the cost structure to actually compete in the global market."
