The company

About BrainIOStream

BrainIOStream LLC is an embedded systems engineering company. We deliver proof of concept systems, prototypes and low-volume production across firmware, hardware and the reverse engineering between them.

Clients

Who we work with

We are not set up to staff a department for a year. We are set up for the projects where something has to exist for the first time and the team has not built one before.

Startups building hardware

You have the product concept and the market. We provide the engineering that takes it from a specification to working hardware.

Software teams adding a device

The application exists and the hardware does not. We develop the device and the firmware interface to the system you already run.

Companies needing low volume

A short production run, or a board whose original supplier is no longer available. Low volume is our standard scope.

How we operate

One team across hardware and software

Most embedded projects fail late: at certification, in production, or in the field after launch. Those failures are usually created early, when the board and the firmware are specified by separate suppliers who never meet. We take responsibility for both.

You work directly with the engineers building your product. Requirements go to the people who implement them, with no account layer in between.

Founded 2018

Firmware, hardware and vehicle electronics delivered for startups, product teams and engineering partners.

Hardware and firmware together

Schematic and firmware are developed under one roof, so an integration problem does not wait between two suppliers to be assigned.

Designed for manufacturing

Test fixtures, programming and automated test are part of the development plan, not a phase that begins after design freeze.

Technology

Platforms and tools we work with

Silicon, toolchains and instruments in current use, so a project does not begin with two weeks of learning the part.

Contact

Talk to our engineers

Describe the product, the current blocker and the required timeline. You will get a technical assessment, including a clear answer if the project falls outside our scope.

We normally reply within one business day. For a hardware assessment, photographs of both sides of the board with the connector visible are usually enough to start.

We keep what you write here so we can reply. What that means in full is on the privacy page.
