Local expertise.
Dutch data, done right.
We design and operate APIs and consumer products for the Netherlands: postcodes, addresses, and integrations that match how businesses and developers actually work here.
Who we are
Frontier Labs
Frontier Labs is a software studio in the Netherlands. We ship end-to-end products: polished frontends, reliable backends, and infrastructure that stays up. Our sweet spot is Dutch market data - validating postcodes, enriching addresses, and wiring those flows into checkout, CRM, and lead tools - without the friction of generic global providers that treat the NL market as an afterthought.
We are developers building for developers (and for teams who just need things to work). Documentation, predictable pricing, and fast responses matter as much as the code.
Transparency & privacy
We do not store personal information
Our postcode and address reference services are built on public, statistical geography - not on dossiers about individuals. We do not keep personal data from API lookups: no names, no marketing profiles, no cross-site tracking from your integration traffic, and no resale of who-looked-up-what.
Queries are processed to return reference data and then discarded from anything that would identify a person. Technical logs, where they exist, are minimized, rotated, and used only to run a reliable service - not to train third-party models or fuel ad networks.
Transparent by design
Pricing and limits are documented upfront. What the API returns is what the docs say - no hidden fields or surprise data categories.
Data stays in purpose
Reference data answers questions about postcodes and addresses. It is not a shortcut to building a people database on our side.
Hosted in the Netherlands
We operate from NL infrastructure with the same straightforward posture we expect from vendors we rely on ourselves.
When you reach out
If you contact us, we only use what you send to reply. We do not sell contact lists or add you to cold outreach pipelines.
Separate Frontier Labs apps where you create an account (for example billing or product login) handle credentials and email as needed to run that product - always for service delivery, not for profiling unrelated to your use of the product.
Infrastructure
Deployment pipeline
From commit to production: code is built, tested, and shipped to our infrastructure automatically, no manual steps, no waiting.
