What we do

    01

    Engineering

    React, Next, Python, Postgres, Cloudflare — built without templates.

    02

    Visibility

    GEO, AEO, AIO. Be cited by the systems that replaced the search box.

    03

    Pipeline

    Inbound that converts because it was triaged, enriched, and qualified.

    04

    Performance

    LCP < 1.5s on throttled mobile. Enforced in CI, not aspirational.

Why us / 02

Why Atellius — and not the agency
that quoted you last week.

  1. 01

    Hand-built primitives, no template fingerprint.

    No shadcn, no Lucide, no Tailwind UI, no Framer presets. Every component is written from scratch in the file that ships. A Wappalyzer scan returns Next.js and React — and nothing else. That is the authorship fingerprint, and it is non-negotiable on every site we ship.

  2. 02

    One studio, one keyboard, one accountable name.

    The person on the discovery call is the person writing the code. No agency layer, no offshore subcontractor, no “senior” who hands the build to a junior team. Every commit on every project is signed by someone you have spoken to directly.

  3. 03

    GEO and AEO baked in, not bolted on.

    We own and operate geo.atellius.com — the same scanner that audits client sites is the scanner agencies white-label from us. AI-search visibility is not a service we resell. It is infrastructure we built, run, and ship into every site we hand over.

  4. 04

    Performance enforced in CI, not in the pitch deck.

    LCP under 1.5s on throttled mobile is a build-gate, not an aspiration. Lighthouse SEO 100 ships on every page or the deploy fails. Real-device numbers, real thresholds, written into the pipeline before a client ever sees the site.

How we work / 03

How a project runs
at Atellius.

  1. 01

    Audit

    Two-week fixed-scope read of the existing system. For a website: GEO + AEO + performance scan, full Lighthouse + real-device pass, schema and entity-authority gap analysis, and a written brief on what to keep, kill, and rebuild. Deliverable: a 24-page PDF and a kickoff call. No discovery phase that bills for six months of slide decks.

  2. 02

    Architect

    One page of architecture, written before any code. Stack choices, data model, deployment topology, third-party integrations, billing model if applicable. Reviewed with you on a single call. Signed off before week three. No “sprint zero” that runs three sprints long.

  3. 03

    Build

    Hand-coded in the file that ships. Weekly demos on a staging URL you can open from your phone. No design-then-development handoff — the person designing the component is the person writing it. You see the work as it exists, every week, in production code.

  4. 04

    Verify

    Performance budgets enforced in CI before merge. Schema and GEO checks re-run against the new build. Real-device Lighthouse pass on throttled mobile. Every claim on the marketing site is mapped to a proof point in the codebase or it does not ship.

  5. 05

    Ship

    Production deploy on a Cloudflare edge, with rollback in one git revert. You get the code, the deploy pipeline, the analytics, and a written handover. Future-legible by design — no proprietary CMS, no licence we control, no rebuild required in eighteen months.

Clients / 04

Clients running our code
in production.

Atellius built the public tools and the paid program portal as one system. A reader can run the BMI calculator, buy a program, and land inside the member area without a second login or a redirect to some third-party course host. The auth, the billing, the program delivery — it is all on the same domain, written for my content rather than retrofitted around a template. That is what I asked for, and that is what they shipped.

Services / 02

Three practices that
sharpen each other.

We engineer the systems, we make them visible to the AI engines that decide who gets cited, and we sort the inbound that follows. The same studio. The same craft bar.

Questions worth answering in prose.

Studio note / 03

So much of what ships in 2026 is the same shadcn page with the same Lucide icons and the same three-column feature grid. It compiles. It deploys. It does not feel like anything.

We build the way we were taught to: from scratch, in browser, with the cursor on the line that matters. The result is sites that hold attention because someone obviously held it while writing them — and that perform because every choice was an actual choice.

If a Wappalyzer scan tells you who built our work, we did not build it.
