Lumina is a senior AI engineering studio for B2B SaaS teams. You work directly with the engineer who designs, builds, and runs your RAG systems, agents, and automations — no agency overhead. EU/GDPR hosting available.

Grounded — a production AI product we designed, built, and run. grounded.sh
Production AI on a modern, model-agnostic stack
You already know AI belongs in your product — support that actually answers, search that understands your docs, workflows that run themselves. But your team is heads-down on the core roadmap, and hiring a senior AI engineer isn't realistic yet. That's the gap we fill: senior AI engineering, on demand, shipped straight into your product.
Clear scope. Clear pricing. A fixed price before any build begins.
From $1,500
In about a week we scope your use case and hand you a working prototype plus a clear, fixed-price build plan. You see something real before committing to a build.
From $6,000
Fixed scope, fixed price, live in 2–4 weeks. We design and ship the feature into your product — a support assistant with citations, RAG search, an agent that takes actions, or a workflow automation.
From $3,000/mo
Ongoing senior AI engineering, billed monthly. New features, steady improvements, and we keep the systems we built running and reliable.
Need EU-based, GDPR-friendly hosting? We deploy and manage it for you as part of any engagement.
The fastest way to judge an AI engineer is to see what they actually ship. Here’s ours: production SaaS, designed and built end-to-end, on the same stack we’ll use for you.
An accuracy-first AI support assistant for SaaS. Every answer cites its source, and it says “I don’t know” instead of guessing — built for teams who can’t afford a confidently wrong bot.
An AI blog-writing assistant that produces long-form, SEO-aware content tailored to a business’s own site and voice. A full product: real-time AI editor, content calendar, and multilingual output.
We figure out, honestly, whether there’s a real and shippable use case. If there isn’t, we’ll tell you.
You see something working, and you know exactly what you’ll get and what it costs. No open-ended retainers to start.
You work directly with the engineer building it. Progress updates as we go, live in weeks.
We keep it running and add to it over time — or hand it off cleanly with docs. Your call, always.
Most agencies sell you a senior in the pitch, then put juniors on the work. With Lumina you work directly with the engineer who designs, builds, and runs your system.
You talk to — and get code from — the engineer who actually builds your system.
A small, senior-only studio means no account managers and a direct line to the person responsible for your project.
10+ years full-stack, deep in RAG, agents, and AI infrastructure — the things your feature actually needs.
We agree exactly what ships and what it costs before we start. No open-ended retainers, no scope creep, no surprise invoices.
