- AI engineering for teams that need production, not demos.

We’re an AI solution engineering firm. We design, build, evaluate, and harden LLM systems end to end — from the first prompt to the production runbook.

Founded by engineers who've shipped and sold AI products. Our founder built a proptech startup offering AI-enriched real estate data APIs, operated it to a successful exit in 2023, and was previously part of startups acquired for over $100M with custom AI / ML and mobile applications at their core.

That track record is why we focus on systems that survive real traffic, real data, and real compliance requirements — not demos.

How we work - AI engineering, grounded in production reality

We build AI systems the same way we’d build any other production software: versioned, observable, tested, and deployed to infrastructure you already trust. No black boxes, no magic, no demo-ware.

  • Engineering first.

    Prompts, evals, and data pipelines live in your repo and ship through CI. We treat AI systems as software, not science projects.

  • Evidence over vibes.

    Every change is measured on your data — retrieval, faithfulness, cost, latency. Decisions come from numbers, not vendor demos.

  • Your cloud, your controls.

    AWS, Azure, GCP. Private endpoints, scoped keys, audit trails, and cost governance from day one. Compliance-ready foundations on request.
