Do you only work with non-profits?

Our focus is purpose-driven organizations — foundations, associations, education platforms and mission-led companies. The architecture itself works for any business: a foundation with regulated receipts and board governance is a harder test than most companies will ever set.

Can a website use real-time 3D without becoming slow?

Yes, if it is engineered for it. We load 3D libraries only when a device can run them smoothly, and give weak devices, data-saver mode and reduced-motion users an elegant static version automatically. The page stays fast; the 3D is a layer on top, never a gate in front.

Can you migrate us from WordPress or our current SaaS tools?

Yes. We have migrated thousands of WordPress articles across five languages, a membership platform with hundreds of members and form services with almost a thousand submissions — without losing content, links or data.

Can an AI assistant run privately, on our own infrastructure?

Yes. We build assistants that answer only from your own documents, with citations, and can run on a server you own with a local language model — so member or customer data never leaves your infrastructure. EU AI Act transparency is part of the design.

Who owns the code, the data and the accounts?

You do. Hosting, payment and database accounts are opened in your organization’s name, the code is handed over with documentation, and you can run the system with us or without us.

How long does a project take?

A focused website or portal takes weeks; a complete architecture with portal, payments, automation and AI took six months from zero at our foundation reference. Every phase has a fixed scope agreed before work starts.

Where are you based, and in which languages do you work?

Sirius Nexum Solutions LLC is registered in Wyoming, USA, and works fully remotely for organizations worldwide. We deliver in English, German, Italian, Portuguese and Spanish.

Most organizations collect tools.We build digital architecture.

Websites, immersive 3D, portals, payments, automation and private AI — designed as one system. One accountable partner instead of five agencies.

What We Build

Six disciplines,one architecture.

Each discipline stands on its own — and each is designed to plug into the others. Every claim below links to the system where it is already working.

Flagship Practice

Digital Architecture

All six disciplines designed as one nervous system for your organization — shared identity, shared data, one design language. One system instead of twenty subscriptions.

Explore the practice

Websites & Multilingual Platforms

Fast, elegant sites that speak your audience’s languages and are engineered to be found — static-first on a global edge network, with structured data and privacy built in.

Design systems & art direction
Multilingual content architecture
Edge hosting, Core Web Vitals, accessibility

Learn more ProofSynchronotron: five languages, some 9,700 pages generated from one source.

Immersive 3D & Interactive Experiences

Real-time 3D in the browser that explains what text cannot: products, models, data and ideas you can turn, zoom and explore — with graceful fallbacks so every device gets a great experience.

three.js / WebGL scenes & 3D heroes
Interactive data and model visualization
Low-power fallbacks, reduced-motion support

Learn more ProofSynchronotron: a 3D matrix hero, a holographic head and eight interactive scenes.

Portals, Memberships & Course Platforms

Members, customers and partners serve themselves: they join, pay, learn, vote and find their documents — in a portal that knows who they are and what they may see.

Member & customer portals, roles and tiers
Course academies with video and certificates
Digital governance: votes, resolutions, registers

Learn more ProofVerein für holistische Gesundheit: 22 member areas and a course academy replace three tools.

Payments, Shops & Automation

A payment arrives, the receipt goes out, the books are updated — automatically. Shops, subscriptions and back-office workflows that run at night so your team does not have to.

Stripe, PayPal, Mollie, Mercado Pago & Pix
Receipts, dunning, reconciliation, reporting
Self-hosted workflow automation

Learn more ProofTerra Humana: donation to receipt to books with zero manual steps.

Private AI & Knowledge Systems

An assistant grounded in your own documents that answers with citations — hosted where you decide, down to a model running on your own server, with EU AI Act transparency built in.

Retrieval-augmented assistants with citations
Local / self-hosted language models
Institutional memory, briefings, reports

Technical SEO & structured data
Content strategy & editorial systems
Lossless migration from WordPress & SaaS

Around the build

Consulting & Advisory

Organizational and governance advisory (non-legal), digital strategy and project concepts for non-profits, associations and foundations.

Education & Enablement

Workshops, webinars, handbooks and team training — every system is handed over so your people can run it.

Media & Campaigns

Video, digital brochures, crowdfunding and outreach campaigns that carry your mission to the people who should hear it.

How We Work

Architecture first,tools second.

01
Map
One conversation, then a written map of your real processes — membership, payments, governance, content — before any technology is chosen.
02
Design
One architecture across all systems: shared identity, shared data, one design language. You approve a fixed scope and a clear price.
03
Build
Delivered in verified increments you can click through. Every payment path and workflow is proven end to end before go-live.
04
Run & hand over
Monitoring, backups and an operations handbook. Accounts, code and data are yours — run it with us, or run it yourself.

Fixed scope and price per phase
Code, data and accounts in your name
No lock-in, documented handover
Privacy and accessibility by design

The Studio

Small by design.Complete by standard.

Sirius Nexum Solutions is a digital architecture studio registered in Wyoming and working fully remotely for organizations worldwide. We close the gap between a mission and the systems that carry it.

Every system is designed and built by a single senior architect, augmented by state-of-the-art AI engineering. That is how one studio delivers what usually takes an agency, an IT firm and three SaaS vendors — with one design language and one person accountable for all of it.

One architect. One accountable partner.

No account managers, no sub-contracted hand-offs, no gaps between systems.

One accountable partner

Website, 3D, portal, payments, automation and AI from one architect — no hand-offs between agencies, no gaps between systems.

Three complete platforms, each designed and built end to end by one studio.

Proven before it goes live

Every payment path, workflow and calculation is tested against reality before anyone depends on it.

73,000+ reference values verified · 567 automated tests and proofs on one platform alone.

Yours, not rented

Accounts, code and data belong to the client. Where it matters, even the AI runs on the client’s own server.

A members’ AI running entirely on the association’s own infrastructure.

Built for purpose-driven work

Governance, donations, memberships, receipts, consent: we know the rules non-profits live by — and build them into the system.

A foundation whose board resolutions and registers run digitally.

Platforms & Migration

Moving 1,600 WordPress articles into five languages — without losing what ranks

Leaving an old WordPress site is easy. Leaving it without losing years of content, search rankings and paying customers takes a plan. Here is ours.

Private AI

A private AI assistant for associations: local model, cited answers, no data leaving the house

Public chatbots guess, and they send your members’ questions to someone else’s servers. A walk through the architecture of an assistant that does neither.

Platforms & Migration

From a 65,000-formula spreadsheet to a verified web app

Many organizations run on one spreadsheet that only experts can operate. Here is how we turned a 56-sheet workbook into a web engine — and proved it right, field by field.

Questions

Asked before every project.

Complete digital systems: multilingual websites, immersive 3D web experiences, member and customer portals, online course platforms, shops and payment automation, workflow automation and private AI assistants — designed as one architecture instead of a pile of subscriptions.
