Decision
Refactor, rebuild or replace.

Technology & Sovereignty
Your technology is an asset or a dependency. Measure which.
Architecture, technical debt, AI, hosting: the choices of the first three years weigh on the next ten. Aegryn steps in at the moments when they are decided.
What we observe
22% → 34%
Swiss SMEs using AI, 2024 to 2025
SECO, kmu.admin.ch
34%
have rules on the data entered into AI tools; 23% among companies with fewer than 10 employees
SECO, kmu.admin.ch
2 Aug 2026
AI Act transparency obligations (Article 50) applicable
Regulation (EU) 2024/1689
What this changes
The risk does not come from the tool, but from the absence of a rule around it.
What you get
01
Named dependencies, with a plan for each non-reversible component.
02
Technical debt that is quantified rather than felt.
03
AI usage rules your teams actually apply.
Six situations
Where you stand. How we step in.
01
02« Only one person understands the system. »

05« We no longer have a CTO. »
Decision
Interim, hire, or fractional leadership.
Deliverable
Interim technical leadership with documented handover.
Fractional engagement
06« Where is our data, and who can access it? »
Decision
EU or Swiss hosting, reversibility clauses, exposure to extraterritorial laws.
Deliverable
Hosting review and reversibility plan.
Short engagement

Our framework
The 90-Day Reversibility Test
For each critical component (host, vendor, provider, AI model, key developer), one question: if it disappears tomorrow, in how many days, at what cost and with what data loss does the service restart?
Reversible within a week
Alternative identified, exportable data, documented switchover.
Reversible within a month
Known alternative, migration to plan, limited functional dependency.
Reversible within 90 days
Replacement possible but costly: partial rebuild, renegotiation, hiring.
Non-reversible
No credible alternative to date. The component conditions service continuity.
Deliverable
Map of the ten most critical components and treatment plan for the non-reversible ones.
By size
SME · 10 to 50 M€
A stack built by accretion, a few developers, some providers. Priority: minimal documentation and reversibility of the three critical components.
Mid-cap · from 50 M€
Legacy information system, several vendors, an IT department. Priority: a modernisation trajectory arbitrated by the committee, and data governance across businesses.
By sector
Finance & Capital
Critical ICT third parties and cloud outsourcing (DORA); resilience architecture.
Health & Life Sciences
HDS hosting in France; separation of health data; AI in a medical device (Annex I, 2 August 2028).
Industry, Energy & Infrastructure
IT/OT, remote maintenance, ownership of industrial data.
Commerce, Services & Customer Experience
Unifying customer data across channels without depending on a single CRM; AI personalisation and GDPR.
Tech, Innovation & Public Sector
Audit before investment or sale; copyleft licences at the core of the product; hosting imposed by public procurement.
Typical scenario · illustrative
Software vendor for clinics, 18 M€ revenue, 14 developers including 6 contractors. A fund takes an interest in the company. Within four weeks: dependencies and debt mapped, three non-reversible components identified, six-month remediation plan costed. The CEO presents it to the fund before the fund discovers it alone.
What an AI tool will not do for you
A coding assistant produces code. It does not answer for the architecture choice, does not know what your hosting contract allows, and will not hold the CTO seat in front of your board.
Implement
Implementing what was decided, through to acceptance.
OUR CONVICTION
Three mission formats
Choose your format.
Depending on your horizon, resources and objective, we adapt the engagement format.
QUICK BUILD
4 to 8 weeks
An operational tool, fast.
To test a use case, automate a process, or fill a gap. Tight scope, fast delivery, full ownership. Examples: tracking dashboard, scoring tool, automated workflow, field mobile app, regulatory reporting.
BUILD TO LAST
Durable tool
A tool built to last.
Full ownership, documented architecture, code any team can take over. For systems that carry your business. Price locked at scoping.
BUILD TO OPERATE
Build + recurring maintenance
We build and we operate.
For organisations without an internal tech team. We deliver the tool and handle operations: maintenance, evolutions, security. One point of contact over the long term.
Software domains
The domains where we build for our clients.
We build only where the market offers no suitable solution, or where independence requires it. Six domains cover recurring business needs, with an AI layer, independence and integration into your existing information system.
01AI Agents
AI agents & business automation
Orchestration of complex workflows by business AI agents connectable to your systems: CRM, ERP, email, documents, APIs, databases. Automation of billing and customer service. Every agent is auditable, with human supervision and quality monitoring.
02AI Governance
Compliance, risk & AI governance
Compliance platform covering EU AI Act, GDPR, Swiss FADP, NIS2, DORA, ISO 27001: processing register, controls, evidence, audit trail. Supplier and third-party risk assessment: contracts, cyber, ESG, concentration, sanctions.
03Cybersecurity
Cybersecurity & digital identity
Cyber risk assessment, asset inventory, incident management, security evidence, compliance mapping. Business onboarding: KYC, KYB, identity verification, beneficial owners.
04Knowledge AI
Documents, contracts & knowledge
Turn your contracts, policies, invoices and documents into actionable knowledge. Risk identification, critical deadlines and priority actions. Subblink, an Aegryn proprietary solution.
05Decision Intelligence
Data, BI & decision intelligence
Causal analysis, scenario simulation, automated recommendations. The software answers: what happened, why, what will happen, what to do.
06Digital Twin
Digital twin of the organisation
Dynamic representation of your organisation: people, applications, processes, contracts, suppliers, data. Real-time answers on dependencies, costs and operational risks.
Sovereignty
Independence by Architecture.
In 2025, 52.7% of European enterprises used paid cloud services, 33% performed data analytics, 20% used AI (Eurostat, 2025). Independence is not a marketing label: it is a verifiable architectural property, applied within the sovereignty framework you choose. Data under Swiss or EU jurisdiction, 100% client IP, AI models deployable without flows to Cloud Act-subject infrastructure without your explicit consent.
Eurostat, ICT usage in enterprises survey 2025 ↗
Data & AI model localisation
Your data and AI models stay in Switzerland or the EU, on your infrastructure or with a certified hosting provider. No processing outside the jurisdiction without your explicit consent.
Ownership & export
100% client IP. Aegryn is never a co-owner of the code. Full export of code, data, models and documentation, at any time.
Zero Vendor Lock-in
Open source, open standards or vendor solutions deployed under European jurisdiction. You can change integrator at any time, without depending on Aegryn or any single vendor.
Auditability & Human Control
Every AI decision is traceable, explainable and reversible. A human validates critical decisions.
Open or sovereign technologies: PostgreSQL, Python, Node.js, Next.js/React, Docker; hosting with Infomaniak, Exoscale, OVHcloud; Mistral models. Integration possible with your existing systems (CRM, ERP, business APIs) and mobile tools (React Native). Non-European tools (OpenAI, Stripe, Cloudflare, etc.) are only used with your explicit consent, documented at scoping.
