What we do
A product that works, ships, and doesn’t fall apart in a regulatory audit.
Here’s how we get you there.
Product Design & Engineering
Design and engineering aren’t two handoffs here. They happen in the same room, as one conversation, which is the only way to avoid the usual trap: a beautiful design nobody can manufacture, or a manufacturable design nobody wants to hold.

Ramp-to-Production
Most product timelines don’t die in concept. They die quietly, somewhere between “it works on the bench” and “it works on the line, ten thousand times a day, without anyone babysitting it.” We close that gap: DFM/DFA, supplier selection, pilot runs, and the unglamorous work that makes a launch date real instead of aspirational.
Innovation & Portfolio Strategy
Somebody in your organization has to decide which three concepts get funded and which twelve get a respectful no. We help you build that muscle so the decision runs on data, not on whoever argues loudest in the room.

The Napkin Protocol
Our method for turning a pile of concepts into the one worth building. Four steps, Napkin Dump to Napkin to Line.
Napkin Dump
Everything out of your head and onto the table, unfiltered. Volume and honesty first. Quality comes later.
The Wipe
Pre-agreed criteria cut what never should have survived the meeting. This is the uncomfortable one.
Fold Test
Can it fold into reality? Fast, cheap pre-validation: prototypes, expert interviews, and an early read on production.
Napkin to Line
The chosen concept becomes a production-ready spec. Full engineering, DFM/DFA, suppliers, and ramp-up plan.
The Napkin Protocol, fixed price.
Four weeks, one decision paper, the 2–3 concepts actually worth your money. Or start smaller with one stubborn concept.
