AI-native / Products & consulting

AI engineering,
from idea to production.

We’re Martyn and Mikkel Garcia, two senior engineers who build AI products and help founders put AI to work. You work directly with the people writing the software.

01 / HOW WE CAN HELP

Useful AI. Working software.

Bring the problem, the idea, or the prototype. We’ll help choose the right approach and build it with care.

Also: rapid prototyping, APIs & integrations, architecture, DevOps and ML infrastructure.

02 / THINGS WE’VE BUILT

We build things
we want to exist.

Products, open source, and experiments of our own. They show what interests us, what we’ve learned, and how we approach the work.

03 / WORKING TOGETHER

Clear thinking.
Direct collaboration.

  1. 01 / UNDERSTAND

    Start with the real problem.

    We’ll talk through the people, the goal, and the constraints. The problem helps decide where AI belongs.

  2. 02 / BUILD

    Make the next step tangible.

    Work directly with us on a plan, a prototype, or working software. We explain the choices and tradeoffs along the way.

  3. 03 / REFINE

    Learn from what works.

    Check the result against the need. Use feedback to decide what to improve and what to do next.

We also co-run Differential AI Lab.

With fellow engineers Gabe and Lee, we work on organizational AI transformation, AI software factories, and agentic boundary enforcement.

BUILT IN THE OPEN

Tools, models, and curiosity.

Sometimes we make a tool because we need it. Sometimes an idea is worth exploring. Browse the source and see what we’re working on.
