Contract Product Development

We turn concepts
into certified products

From medical devices to industrial equipment, we help founders, clinicians, and engineers navigate the full journey — prototyping, manufacturing, regulatory approval, and everything in between.

What We Do

Full-spectrum product development

We work across the full product lifecycle — from napkin sketches to shipped units. No stage is too early, no challenge too complex.

🔬

Feasibility & Concept

Technical feasibility analysis, regulatory pathway assessment, and concept refinement to de-risk your idea before major investment.

⚙️

Engineering & Prototyping

Mechanical, electrical, and firmware engineering. We build functional prototypes that prove your concept and attract funding.

🏭

Design for Manufacturing

DFM analysis, tooling oversight, and production process development to ensure your design scales efficiently and cost-effectively.

📋

Regulatory Strategy

Regulatory planning, technical file preparation, and submission management for TGA, FDA, CE Mark, and other global markets.

Quality Systems

ISO 13485 quality management system setup, DHF/DMR documentation, and audit readiness for medical device manufacturers.

🚀

Scale & Supply Chain

Contract manufacturer selection, supply chain setup, and production launch support to get your product to market reliably.

Case Study

From idea to TGA submission

Medical Device — Class IIa

Point-of-Care Diagnostic Device

A clinician came to us with a novel diagnostic concept. We took it from early prototype through to a completed TGA registration — on time and on budget.

What we delivered

  • Complete technical file and design history documentation
  • Risk management file (ISO 14971) and usability engineering report
  • Design verification and validation protocols and reports
  • Manufacturing transfer to contract manufacturer
  • Quality management system implementation (ISO 13485)
  • TGA submission management and agency correspondence
  • Post-market surveillance planning

"We handle the regulatory complexity so our clients can focus on their patients and their business."

How We Work

A structured, transparent process

We break complex projects into clear, manageable phases. You'll always know where we are and what's next.

01 — DISCOVER

Understand & Assess

We dig into your concept, constraints, and goals. We identify regulatory touchpoints and technical risks early.

02 — PLAN

Scope & Roadmap

We deliver a detailed project plan with timelines, milestones, regulatory pathway, and budget estimates.

03 — BUILD

Engineer & Prototype

Design, build, test, iterate. We run lean with frequent check-ins and design reviews.

04 — VALIDATE

Verify & Submit

Design verification, regulatory submission, and audit preparation. We manage the process end-to-end.

Engineering-first product development

ProtoPhysics was founded on a simple premise: the best products come from engineers who understand both the technical and regulatory landscape — and know how to navigate both.

We work with founders building their first hardware product, clinicians with a clinical need, and established companies looking for a reliable development partner. Our focus is physical products where quality, compliance, and manufacturing matter.

Passion projects, real products

ProtoPhysics is built by a team that ships. Here are two live products born from the same engineering-first mindset.

Fencemate.ai
LLM-Arbitrated Escrow
LIVE

Smart contract escrow for neighbour fence disputes. An LLM acts as independent adjudicator — neighbours fund a contract, upload photos via vision AI, and payment releases only when both sides confirm satisfactory work. Eliminates conflict and upfront cash demands.
