About — Samuel Archibald, Paximi

Paximi is the consulting practice of Samuel Archibald, an engineer who works across the full anatomy of a physical product: the circuit boards, the firmware that runs on them, the software that talks to them, and the enclosures and processes that turn a bench prototype into something manufacturable.

The practice grew out of a pattern Samuel kept seeing: founders with genuinely good product ideas stuck between two bad options. Development agencies wanted agency budgets and delivered by committee. Individual freelancers were affordable but covered one discipline, leaving the founder to be their own systems integrator. What those founders needed was a single engineer senior enough to own the whole problem — and accountable, personally, for the result.

That accountability is the product. When you work with Paximi, the person you talk to is the person doing the engineering. Nothing is lost in translation between a salesperson, a project manager, and a rotating bench of developers, because those are all the same chair here.

Samuel works with clients across the United States, remotely by default, and has a particular fondness for the awkward, ambitious projects where hardware and software have to work as one thing.

How the work gets done.

Working checkpoints, not status reports. Progress you can hold beats progress you can only read about. Engagements are structured around demonstrable milestones — a board that powers on, a sensor that reads true, a demo that survives being run by someone other than its author.

Manufacturability is a day-one concern. The cheapest time to fix a production problem is before the design exists. Every component choice and mechanical decision is made with an eye on what it costs at volume and who can supply it.

Honesty about risk. Every ambitious product has open technical questions. Pretending otherwise fails in diligence, where it is most expensive. The practice here is to name the risks, rank them, and retire the scariest ones first — and to put that reasoning in writing for your investors.

Your product, your property. Designs, code, and documentation belong to you when the invoice is paid. The goal is to make yourself unnecessary: by the end of an engagement you should hold everything a future team needs to carry the product forward without me.
