About us

Embedded engineering with real experience

We are an engineering consultancy specialized in firmware and hardware. We take electronic products from prototype to production for startups, industrial SMEs and large companies — remotely, in any time zone.

More than 10 companies and over 20,000 devices in the field back our work: wireless connectivity, low power, board design and robust, documented, maintainable code.

  • Direct communication with engineers, no middlemen
  • Commitment to deadlines and code quality
  • Full confidentiality (we work under NDA)
  • From concept to manufacturing, in a single team

How we work

  1. UnderstandWe analyze your technical challenge and goals.
  2. ProposeWe define architecture, scope and timeline.
  3. DevelopWe iterate with deliveries and continuous communication.
  4. DeliverValidated, documented product, ready to scale.

How we work with you

Engagement models

We adapt to how you prefer to work. We define scope, timeline and budget before starting — no surprises or hidden fees.

Fixed project

Fixed budget and timeline after analyzing your challenge. Ideal when the scope is clear and you want a defined deliverable.

Hourly

Flexible hour packages for support, iterations or open scope. You pay for what you need.

Monthly retainer

An engineering team available each month, as an extension of yours. For ongoing collaboration.

Common questions

Frequently asked questions

Yes. We help from the idea and prototype to production. We can start with a proof of concept and scale to a final product.

Yes, we work remotely with clients worldwide, in Spanish and English, with continuous communication and regular deliveries.

Of course. We routinely work under NDA and treat all your project information confidentially.

Both. We can design the hardware (schematic and PCB) and develop the firmware, or join a specific part of the project.

The first consultation is free of commitment. You tell us your challenge, we analyze it and propose an approach, scope and timeline.
