    Hardware mistakes are cheap to make and expensive to unmake

    Most startups don't need a full-time hardware CTO. They need one on the days it matters.

    First time through the whole loop

    Your team can build the thing. What nobody there has done yet is take it through certification and into production, where the mistakes get expensive and slow to undo. We've run that loop many times.

    Suppliers set the agenda

    Your manufacturer says it can't be done, or quotes extra tooling, and you have no way to judge whether that's true. So quotes go unchallenged and timelines slip.

    Slow answers, expensive detours

    Certification, supply chain, firmware architecture. You can spend a week googling every question, or twenty minutes asking someone who has answered it before.

    One number to call for everything hardware

    We sit on your side of the table. Not the factory's, not the lab's.

    Firmware & production

    Architecture and code reviews, debugging help, production issues, yield questions. From board bring-up to batch three.

    Certification

    CE, FCC and the new cybersecurity rules. We plan certification into the design, so lab time is a formality instead of a lottery.

    Supply chain

    Component choices, shortages, second sources and cost-downs. We read the quotes before you sign them.

    Your manufacturer, managed

    We run the day-to-day with your factory or ODM: asking the right questions, challenging DFM feedback, chasing whatever stalls.

    Testing & hardware-in-the-loop

    Test plans, HIL setups and production test fixtures, so regressions surface on your bench and not in the field.

    Security reviews

    Firmware and device security reviews, and a straight answer on what the Cyber Resilience Act means for your product.

    How the retainer works

    Light on process, heavy on availability.

    An agreed number of hours a month

    Reserved senior capacity, set with you up front and spent where it helps most that month: reviews, supplier calls, debugging, planning.

    A check-in every two weeks

    Strategy call and brainstorm. We come prepared with updates on every open item, so you never have to chase us.

    Call or WhatsApp any time

    A question shouldn't wait two weeks. Send it when it comes up and you'll get a short answer fast.

    Three months to start

    Long enough to prove it works. After that it's monthly cancellable, so we have to stay useful.

    Who you get

    No juniors, no account managers. The people on the call do the work.

    We've had these problems ourselves

    A fair share of the grey hairs came from hardware. We'd do it all again.
