One Dutch partner for municipalities, public agencies and central government. From information management, data quality and geodata to AI visibility and the Cybersecurity Act — in the language, pace and procurement process of the public sector.
Who we work for
Municipalities and central government face the same obligations, but at a different pace, mandate and procurement process. In both cases we start with a bounded baseline and grow on evidence.
Services to residents, the zoning plan, the heat transition and the open government act — with limited capacity and a budget being written right now.
National registries, chain collaboration and supervision at scale — where governance, archiving and AI accountability must be demonstrable.
Agenda 2026–2027
From archiving to AI and from wallet to zoning plan: the 2027 obligations are already known — and the budget that has to fund them is being written right now. A baseline assessment, a register and demonstrable governance take months, not weeks. Start now and you account with evidence instead of promises.
New executives are drawing up their first full budget — the room for data, geodata and resilience in 2027 is being decided right now.
Decentralised governments are essential entities regardless of size: registration, duty of care, incident reporting, RDI supervision and BIO2 as the anchored framework.
The AI literacy duty (Feb ’25) and the transparency duty for chatbots and AI content (Aug ’26) are already enforceable.
(Semi-)public service providers must accept the European ID wallet alongside DigiD; relying-party registration and application changes run into 2027.
Permanently retained information must be transferred after 10 instead of 20 years — digital information management has to be demonstrably in order sooner.
New information categories are expected to become mandatory for active publication, in tranches in January, April and October 2027.
Since 1 Jan ’26 changes are only possible in STOP/TPOD and TAM plans must be converted by end 2031 — BAG and BGT data quality is the precondition.
Requirements on risk management, human oversight and EU-database registration — the window to build an AI register, IAMAs and governance is now.
Four questions, one partner
Visibility, foundation, resilience and the physical domain. Every question starts with a bounded baseline and grows into structural collaboration.
Residents and businesses ask AI assistants first. We test what those answer and make sure your own information decides the answer.
Data quality, governance and archiving in order — the precondition under open government, the Archives Act and responsible AI.
Your external attack surface mapped, tested against the duty of care and translated into a prioritised action list for accountability.
Heat transition, housing, climate adaptation and the zoning plan — substantiated at address, neighbourhood and area level.
Geodata & the physical domain
Heat transition, housing, climate adaptation, the zoning plan: what municipalities are held accountable for is spatial. We combine base registries (BAG, BGT, WOZ), CBS neighbourhood data, liveability and climate data — and your own sources where wanted — into analysis at address, neighbourhood and area level. Public sources and your own data only, privacy by design.
Which neighbourhoods first? Substantiated on construction year, energy labels, housing types and social indicators — from map to delivery sequence.
Location and plan-capacity analysis, target groups and mobility per neighbourhood and pressure on amenities — input for your housing programme.
Heat stress, flooding, subsidence and foundation risk per neighbourhood and building, translated into a prioritised adaptation agenda.
Data quality and coherence of BAG and BGT in order — the geodata basis under STOP/TPOD, the DSO and a reliable area-wide zoning plan.
Preconditions in order
Controls designed to ISO 27001 and BIO2 principles; we share the current certification status transparently in every engagement.
Standard processing agreement and clear arrangements on data ownership and retention periods.
Storage and processing of government data within the Netherlands/EU. On-prem, hybrid or EU cloud — the choice and control stay with you.
Privacy by design, DPIA support and clear upfront agreements on purpose limitation, retention and data minimisation.
We think along on Social Return obligations and deliver on them within the assignment where appropriate.
Based in Hilversum, with Dutch-speaking contacts and knowledge of the municipal context. Registration and references available on request.
How we start
Trust comes from evidence, not promises. So we start small and grow on results.
We start with one productised baseline below the tender threshold. Fixed price, fixed scope, a concrete report within weeks.
Based on the baseline we take on one bounded question and make the result measurable — usable as a reference inside and outside the organisation.
Structural collaboration through your regular procedure — TenderNed, a DPS or your procurement partnership — so multiple municipalities can benefit at once.
Why Liplyn
Not a consultancy that still has to learn the public data landscape. We run production systems on open government data — from CBS and Kadaster to RDW, police open data and RIVM — and know what it takes to unlock them reliably and responsibly. Our origins are in location intelligence: analysis at address, neighbourhood and area level is a core specialism.
Since 2008, pages per municipality built on open data: public notices, permits, chamber-of-commerce changes and land registry transactions.
Our data arm manages petabyte environments in healthcare, research and government: storage, archiving, governance and managed services.
CBS neighbourhood data, Kadaster, police open data, Leefbaarometer, RIVM, DUO, energy labels — responsibly unlocked from public sources only.
Short examples of how our most relevant data services turn into concrete results in this sector.
Datasets lived in separate systems and were published by hand, twice a year.
Automated publication pipeline with metadata standards and a public API.
Every department reported different numbers to the same council question.
Shared definitions, a governed semantic layer and self-service dashboards.
An annual pentest was the only insight into exposed systems.
Always-on asset discovery and vulnerability monitoring with HaxUnit.
Matched to the public sector based on topic tags and how often each service is deployed here. Every data service and product has its own page with scope, deliverables and FAQs.
No sales pitch, but a concrete conversation about your 2027 agenda and the first measurable step towards it.
A short 30-minute introduction and together we determine which baseline delivers most for your organisation. Without obligation, and fully in line with your own procurement process.
Fixed scope, fixed price and a report that is usable for the organisation and for political accountability.
