Ongoing Partnership

For established companies that need consistent development support and predictable monthly costs across production and long-term product evolution.

Best ForEstablished companies that need a long-term development partner.

Engineering Capacity Without the Hiring Overhead.

Building and maintaining an in-house team across electronics, embedded software, cloud, mobile, and AI is expensive, slow, and hard to scale up and down. Hiring across this many disciplines is hard. Keeping them all busy when the roadmap shifts is harder.

The Ongoing Partnership gives established medical and wellness device companies the technical breadth of a full internal team, with the flexibility to focus capacity wherever your product needs it most this quarter.

With over 25 years of experience, we plug in as an extension of your team, with engineers who learn your product and stay with you over time.

Who This Is For.

  • Established medical and wellness device companies with ongoing development needs
  • Teams managing pre-production, production, or long-term product evolution
  • Companies that need predictable monthly engineering budgets
  • Organizations that need to scale capacity up or down as roadmaps shift

What's Included.

Dedicated engineering capacity across electronics, firmware, cloud, mobile, and AI/ML
Predictable monthly cost with clear monthly deliverables
Long-term relationship with engineers who know your product and team
Flexibility to scale support up or down as your roadmap evolves
V&V testing, regulatory documentation, and post-market engineering support
Direct access to the engineers doing the work

A simple, flexible path forward.

01
Start the Conversation

Talk directly with our team about your products, your roadmap, and the engineering gaps you're trying to fill.

02
Define the Right Partnership

We scope capacity, disciplines, and monthly cadence based on what your roadmap actually needs, not a generic package.

03
Plug In and Move Forward

Our engineers integrate with your team and start delivering, while your internal team stays focused on the work only they can do.

What Working With C3 Looks Like.

An Extension of Your Team, Not a Vendor

We integrate into your processes, your tools, and your communication rhythms. Our engineers learn your product, your codebase, and your regulatory documentation, and they stay with you.

Cross-Disciplinary Under One Roof

Need electronics this month and cloud next month? Need firmware support while we also build a companion app? You get one accountable partner across all of it.

Long-Term Relationships, Real Continuity

Many of our retainer clients have worked with us for years. The same engineers who shipped your first product can support your fifth.

How We Approach Retainer Engagements.

Right-Sized From the Start

We don't sell more capacity than you need. The right retainer is one where the monthly cost maps cleanly to monthly value delivered.

Predictable, Transparent, Flexible

You get a predictable monthly invoice with transparent reporting on what was delivered. If the roadmap shifts, we adjust capacity rather than forcing your needs into a fixed bucket.

Built for Long Product Lifecycles

Medical and wellness devices stay in the field for years. We're built to support products through that full lifecycle, from launch through end-of-life and everything in between.
