Product Development Consultancy
From product concept to investor-ready reality.
Paximi is the product development practice of Samuel Archibald, an engineer who takes founders from a promising idea to a working, physical product — and to the manufacturing plan and documentation that make investors take it seriously.
Start a conversationThe Practice
One engineer, accountable for the whole product.
Most early-stage hardware ideas die in the gap between a concept and a thing you can hold. Agencies quote six figures to cross that gap; a single freelancer usually covers only one discipline. Paximi exists for that gap: one senior generalist who works across electronics, firmware, software, and mechanical design, and who has an eye on manufacturability from the first sketch.
The result you walk away with is not a slide deck. It is a functioning first version of your product, a realistic plan for producing it at scale, and a technical narrative you can put in front of investors with confidence.
Services
Three ways we work together.
Method
How an engagement runs.
Discovery
We define what "investor-ready" means for your product: the demo it must perform, the questions it must answer, the budget and timeline it must respect.
Design & Engineering
Electronics, firmware, software, and enclosure design in short iterations, with working checkpoints you can see and hold along the way.
Build & Validate
A functioning prototype, exercised against the scenarios that matter — demo-day conditions, not lab conditions.
Package the Story
Manufacturing roadmap, cost model, and technical documentation that let an investor's diligence go smoothly instead of stalling the round.
