The verticals most agencies won’t touch — auto parts data, ERP, and regulated healthcare.
We shipped a 10M-SKU auto parts platform for a German B2B distributor. Wrong-fit returns dropped 45% in 90 days. Before us, their search took 4.2 seconds. Now it takes 620ms.

What we’re actually good at
Custom software, data platforms, and regulated systems — delivered by the same senior engineers from discovery through second-year support.
Why us over the next ten agencies on your list
We’re narrow on purpose. If your system is mostly a marketing site or a CRUD app, there are cheaper teams. If it has to be correct, audited, and still alive in five years — that’s us.
Domain depth, not generalist devs
We've shipped OEM catalogs with millions of SKUs, ERPs running real construction projects, and laboratory systems used in patient care. We don't learn your industry on your budget — we walk in already speaking it.
10M+ SKU fitment engine shipped for DACH automotive B2B
One accountable team, full bench depth
Vireon Labs aggregates senior capacity from established Vietnamese companies under a single contract and a single PM. You get bench depth without the handoff chaos — we can't hide a missed sprint behind a subcontractor.
Single contract covers design → development → support
Built for systems that get audited
Our healthcare work ships under ISO 13485 quality processes; our ERP work survives finance and inventory audits. Traceable requirements, reviewed code, documented decisions — carried into every project by default.
ISO 15189-compliant LIS, DATEV-integrated ERP
EU-hour squads, written communication
Senior engineers overlap the European workday in writing — specs, decisions, and tradeoffs live in your tools (Linear, GitHub, Notion). Async by default, sync when it actually moves the project.

Our Process
How a project actually runs
No surprises. Every engagement starts with 2–4 weeks of structured discovery before a single line of code. Every step has a written deliverable.

Planning & Design
We create detailed technical architecture, user experience flows, and project roadmap.
2-3 weeks
3
Development
Our team builds your solution using agile methodology with regular sprint demos and updates.
8-16 weeks (varies)
4
Testing & QA
Comprehensive testing including functional, performance, security, and user acceptance testing.
2-3 weeks
5
Deployment
We deploy to production with zero-downtime strategies and comprehensive monitoring.

Testimonials
What clients say after delivery
Unsolicited feedback. No NPS surveys, no review campaigns.
“Two ERPs before Vireon. Both were cancelled in pilot. The difference this time was the two weeks they spent on our construction sites before writing a single line of code. They shipped a system our foremen actually use. Approval times went from 5 days to under 1.5.”
Andreas Becker
Head of Operations · General contractor, Northern Germany
“They rebuilt our auto parts catalog from scratch — 10M+ supplier records, normalized and searchable. Search went from 4.2 seconds to 620ms p95. Wrong-fit returns dropped from 7.4% to 4.1%. The commercial team can finally run campaigns without a week of manual SKU cleanup.”
Markus Hoffmann
CTO
“Rolling out promotions across 120 stores used to take 3 days and a vendor change request every time. Now category managers ship campaigns themselves in under 2 hours. The platform survived our busiest weekend on record without a single incident.”

Security & Compliance
Built for regulated EU workloads
Our engineering practice is shaped by clients in healthcare, automotive supply chain and construction ERP — domains where governance and traceability are non-negotiable.
GDPR awareness
EU data protection considerations baked into discovery: data minimisation, lawful basis, DPA-ready contracts and EU-region hosting on AWS / Azure when required.
Secure SDLC + OWASP
Threat modelling, dependency scanning, OWASP ASVS-aligned reviews, and CI checks for secret leaks, vulnerable packages and misconfigurations before merge.
RBAC & least-privilege
Role-based access control, audit-grade authentication (SSO/OIDC), and infrastructure access via short-lived credentials — no shared production logins.
Audit logging & traceability
Structured audit trails for sensitive actions (clinical / financial / approvals), tamper-evident log shipping, and retention policies that match client compliance regimes.
Formal certifications (ISO 27001, SOC 2) are not yet on our wall — we partner with clients who carry them and operate inside their security and audit requirements.
