Use AI to get your product where it needs to go.

We start as consultants. We help you find where AI actually moves a physical product forward, set your team up to use it well, and check the work before the expensive steps. Engage us for one piece or several.

01

AI opportunity & feasibility

Work out where AI actually moves your product forward, both in how it gets built and in what it can do, and where it doesn't. You get a straight answer before you spend on it.

  • Product goals, constraints and roadmap review
  • Where AI shortens design, firmware and test cycles
  • Where AI belongs in the product itself, such as on-device DSP or ML, and what it costs in power, latency and BOM
  • A written recommendation with a staged plan
02

AI-enabled engineering workflow

Help your team use AI across hardware and firmware work (specs, part selection, schematic capture, code, test), with the verification that makes the results trustworthy.

  • Tooling and workflow setup, such as AI-assisted KiCad and firmware pipelines
  • Verification practice: primary datasheets, live stock, independent review
  • Spec-driven development your team can keep running without us
  • Hands-on pairing on a real piece of your product
03

Architecture & design review

An independent, AI-assisted review of the architecture, schematic or firmware before an expensive step, such as ordering a board spin, placing a production order or launching.

  • System architecture and component choices
  • Schematic review with issues ranked by severity
  • Firmware structure, real-time budgets, update paths
  • Port feasibility, for example taking a plugin to a pedal
04

Fractional technical & delivery lead

Delivery leadership for a product that's part software and part hardware: scope, stages, decisions and risks, run by someone who has led AI delivery at enterprise scale.

  • Engagement shaping, staging and estimation
  • Technical leadership across in-house teams and contractors
  • Vendor, fab and supplier coordination
  • Progress and decisions your stakeholders can see
When it fits

Full-service delivery

When it makes sense, the engagement can grow into building the product with you: specification, schematic and PCB, firmware and DSP, prototype bring-up and production handoff. It's the same AI-accelerated process we use on our own hardware.

  • Schematic capture and PCB design direction
  • Firmware, DSP and board bring-up
  • Prototype builds, measurement and iteration
  • Manufacturing files, test fixtures and documentation

How it works


  1. 01

    Conversation

    Free. Tell us the product and the goal, and we'll tell you honestly whether we can help.

  2. 02

    Discovery

    A short, fixed-price piece that ends in a written view of the opportunity, the risks and a plan.

  3. 03

    Consulting

    Advisory, reviews, workflow setup or a fractional lead, scoped to what the product needs.

  4. 04

    Full delivery

    Optional. We build it with you, from spec to prototype to production handoff.

Every stage ends with something you keep, such as a written plan, a review, a working AI workflow or, later, boards and manufacturing files. You can stop at any stage and still walk away with value. See the process on our own hardware in 4B Core.
