For Product Companies

One team for the whole product.

For founder-led hardware and IoT companies who need firmware, cloud, and an app — and are tired of stitching three vendors across three time zones. We build the board, the firmware, the backend, and the app as one accountable team, and we fabricate in-house.

01Where It Hurts

Three vendors, three seams

01

Three vendors, three seams

Your firmware shop, your cloud contractor, and your app agency each own a slice and none owns the whole. Every seam between them is where schedules slip and defects hide — and you are the only one holding all three accountable.

02

Prototypes stall before production

A demo that works on the bench is not a unit you can manufacture. Most teams get stuck on the path from a working prototype to a repeatable, testable, shippable product — and the momentum dies there.

03

The runway clock

Pre-Series-B, every month spent coordinating vendors is runway you can't get back. You need velocity from a team that owns the outcome, not a coordination tax paid in status meetings across three time zones.

04

Hardware and software don't converge

When the enclosure is designed after the board and the firmware is written against a datasheet instead of the real silicon, the first prototype teaches instead of works — and every lesson costs another spin.

02How We Help

One team, silicon to cloud

01

Hardware & robotics — one team

PCB design and validation, embedded firmware on RP2040-class MCUs, mechanical design in Fusion 360, and robotics — one team from the board to the dashboard, so the electronics and the enclosure are designed to fit on the first prototype.

Hardware & Robotics
02

Physical AI on the device

Intelligence that runs where the product lives: on-device inference paired with a PostgreSQL and Node backend, OTA-updatable so the fleet keeps getting smarter after it ships — not a static box that ages the day it leaves the bench.

03

The Lab — proof you can visit

In-house FDM printers, CNC machines, and PCB test rigs in Texas. We prototype and run short production without waiting on tooling, and firmware is written against the real silicon at the bench. The proof is the shop floor, not a slide.

Inside the Lab
04

One accountable partner

The board, the firmware, the backend, and the app come from the same room. One throat to choke, one roadmap, and no integration seam between a board house, a firmware contractor, and an app agency — because there isn't one.

How we work
03Proof

The proof is the bench

We don't ask you to take the one-team pitch on faith. The Lab is a real workshop floor in Texas — FDM printers, CNC machines, and PCB test rigs — where prototypes are built and short runs ship without waiting on tooling. Come see where your product gets made.

04Questions

Frequently asked

RefInquirySt.
PRD-001Do you actually build the hardware and the software, or subcontract one?
Ans.
Both, with one team, and that is the whole point. The same people design the PCB, write the firmware, stand up the PostgreSQL and Node backend, and ship the web dashboard. You get a single accountable partner from silicon to cloud instead of stitching together a board house, a firmware contractor, and an app agency across three time zones and three invoices.
PRD-002Can you take us from a working prototype to production?
Ans.
Yes — that gap is exactly where we live. We prototype and run short production in-house on FDM printers and CNC machines in Texas, so pilots ship without waiting on tooling. When volume outgrows in-house fabrication, we hand a contract manufacturer a documented, production-ready package — drawings, BOM, and firmware — and stay involved so the transfer doesn't lose fidelity.
PRD-003We're pre-Series-B. How do you engage without burning our runway?
Ans.
By removing the coordination tax rather than adding to it. One team owning firmware, cloud, and app means fewer seams, fewer status meetings, and fewer months lost to vendors pointing at each other. We scope engagements to your milestone and your runway — the honest way to start is a conversation about the specific product and what has to be true for your next raise.
PRD-004Which microcontrollers and stack do you build on?
Ans.
We default to RP2040 / Raspberry Pi Pico-class parts for cost-effective embedded work and ESP32 when built-in Wi-Fi or Bluetooth is needed, and we'll pick a different MCU when power, peripherals, or supply chain demand it. Whatever the silicon, devices talk to our house stack — a PostgreSQL and Node backend — over MQTT or a custom protocol, and every fleet ships OTA-updatable.
PRD-005Where is the hardware actually made?
Ans.
Prototypes and short runs are fabricated in-house in Texas on our own FDM printers and CNC machines. That proximity is deliberate: the people writing the firmware can walk over to the bench where the board is being brought up, which is how first prototypes end up working instead of teaching.
