IoT platforms your city actually owns.
Zero46 designs and builds sensor data platforms for water, energy, and city operations. Vendor-neutral, NIS2-ready, and handed over to your team. No licenses, no lock-in.
Built from inside government: platform architecture for Sweden's third largest city, 8 years of meter fleets and connected infrastructure.

// what's at stake
Why city IoT stalls.
Run connected infrastructure for a few years and the estate ends up here. It's normal. It's also fixable.
01
NIS2 is in force.
Connected infrastructure is in scope, and most IoT estates cannot show compliance.
02
The vendor owns your platform.
Your data model, your integrations, and your exit cost sit with them.
03
Pilots that go nowhere.
Proofs of concept that never survive procurement or production.

// 01 · ownership & control
You own everything we build.
Where the code lives, who reaches the data, how you get it all back if we're gone. Decided on day one, in writing.
The data is yours.
Your storage, your keys, your retention.
The architecture is yours.
Documented decisions, in plain language.
Replaceable on purpose.
Run it yourself, or hand it to anyone else.
Deploy where you want.
On-prem, sovereign, EU, or hyperscaler.
Built for the regulation.
NIS2, DORA, CRA: in scope by design.
// 02 · who it's for
IoT for water, energy, smart buildings, and connected care.
Public bodies and the operators around them. Same fragmentation, same regulation, same answer: a platform you own.

NIS2 IoT Readiness Assessment.
NIS2 is in force and your connected infrastructure is in scope. In 2 to 3 weeks we review your IoT estate against a 48-control instrument mapped to NIS2 Article 21. You get a written report, prioritized findings, and a remediation path your team can execute.
- Fixed scope, fixed fee, 2 to 3 weeks, remote or on site
- 48 controls mapped to NIS2 Article 21
- Covers architecture, data ownership, vendor dependencies, isolation, event pipeline, persistence, observability, and security posture
- Deliverable: written report, prioritized findings, remediation path
// 05 · how we work
How we work: fixed scope, named end.
Every engagement has a clear output, a set price, and a named end. A full build runs Discover, Design, Build, Operate in 3 to 9 months. Pick a way in.

// 06 · about zero46
Senior people only.
Zero46 is a small, senior firm in Malmö, Sweden. That smallness is the point: no handoffs, no juniors, no account team.
founder · engineer · malmö
Eight years of shipping meter fleets, alarm systems, and data platforms shaped how Zero46 works. The architect who scopes your project is the one who builds it. No handoffs, no juniors. When a project needs more hands, a specialist network backs the build; the architect stays.
We also sit on the buyer side: Zero46 writes the security and NIS2 requirements that go into public procurement documents.
If it needs to survive production, we want to hear about it.

// 07 · faq
Frequently asked questions.
Short answers. Ask if yours isn't here.
If you run water, energy, health, or municipal digital infrastructure, very likely yes. The readiness assessment answers it precisely, control by control.
You do. Code, data model, infrastructure, documentation. Zero46 keeps nothing and licenses nothing.
Four named stages: Discover, Design, Build, Operate. Each has a clear output, a set price, and a named end. Most projects run 3 to 9 months end to end.
No. The advice isn't tied to a vendor quota. If you're on AWS, Azure, or on-prem already, we work inside it.
Fixed price per stage, scoped on the first call. Each stage has a set number before it starts, so no surprise invoices.
The architect who scopes the project. Behind that: eight years of production IoT, including smart-meter fleets at Waltero, alarm systems at Careium, industrial data work via Axians and PRYM.io, and platform architecture for Sweden's third largest city. The person on your first call is the person writing the code.
Small and senior by design. You work directly with the architect, backed by a specialist network when projects need more hands.
Malmö, Sweden. We work across the EU and beyond, on site when it helps, remote when it doesn't.
You keep the code, the documentation, and the know-how. We offer light support afterwards if you want it.
