HÄLYTIN — Taiga's response to the SIREN project
Two years.
Or one weekend.
Finland's SIREN project is scheduled to ship in December 2027. Taiga produced an implementation package over one weekend that can do the same: the specification, architecture, regulatory analysis and a reference implementation. We hand the package to the Finnish state pro bono.
Same end goal. Two timelines.
Both are aimed at the same thing: a drone-threat alert on citizens' phones. The difference is in how the preparatory work gets done.

What the implementation package contains
We hand the full package to a verified representative of the Finnish state pro bono — no licences, no conditions, no later invoices. The package contains everything a production-grade drone-alert application needs, with the exception of authority interface integrations, infrastructure choices and certifications. Those cannot be done without access to government systems.
- ✓Requirements specification and use cases
- ✓Application architecture definition
- ✓Technical specifications and API descriptions
- ✓Data models and data lifecycle descriptions
- ✓Threat models
- ✓Data Protection Impact Assessment (DPIA)
- ✓Regulatory analysis and compliance mapping
- ✓User flows and UX mockups
- ✓Project plan optimised for agent-driven implementation
- ✓Reference implementation source code
- ✓Test cases and test documentation
- ✓Build, deploy and operations runbooks
Examples from the package
Below are examples of the package's output. The full package — including specifications, code and technical documents — is handed over separately to a verified representative of the state.

What this page does NOT show
We do not publish the application source code, detailed threat models, interface definitions or other technical details on this page. The reason is simple: if the state adopts the package, it must be free to decide which technical details of its alert system to make public. Access to the full package is arranged directly with a verified government representative.
How HÄLYTIN was built
Taiga is building a software factory for regulated industries. A traditional software project advances through meetings, specifications, coding and reviews — months before the first end user sees anything. Most of the time goes not into coding but into waiting, coordination and uncertainty.
Taiga's operating model is different: a human describes where to go — the goals, the boundaries, the quality criteria. The platform does the rest. It researches the regulatory landscape, designs the architecture, produces the specification, the code and the documentation. Every decision is traceable, every choice justifiable, every action compliant. Speed AND control — not either-or.
HÄLYTIN was built this way over a single weekend. What a traditional project would have needed a six- or seven-figure consulting team and months to produce, came out of a small team directing the platform as it executed. The same model works for other regulated domains: banking, healthcare, defence, energy.
Input
- ·A drone-alert application for Finnish citizens
- ·Meets regulatory requirements (authority operations, data protection)
- ·Cloud-agnostic architecture
- ·iOS + Android
- ·Understandable to an ordinary user
- ·Domestic data sovereignty
Production
- ·Researched the regulatory landscape (EU emergency communications directive, Rescue Act, data protection)
- ·Designed the architecture and chose the technologies
- ·Produced the specification, API descriptions and threat models
- ·Produced the reference implementation source code
- ·Produced the documentation and architecture diagrams
- ·Implemented the tests
Direction and approval
- ·The team set the direction for the platform
- ·Reviewed the critical decisions
- ·Approved the final result
A production application can be built from this package in several ways: with Taiga's own agent orchestrator, with Claude Code, with OpenAI Codex, with closed on-premise AI coding agents — or, if needed, conventionally with human coders. Once the interfaces, target environment, infrastructure and network architecture are decided, the implementation phase is an order of magnitude faster than a traditional software project.
Offer to the Finnish state
We hand over pro bono
- ✓The application architecture definition
- ✓Technical specifications and API descriptions
- ✓Threat models and DPIA (Data Protection Impact Assessment)
- ✓Regulatory analysis
- ✓Project plan optimised for agent-driven implementation
- ✓Reference implementation source code
- ✓Access to the Taiga platform to finish and deliver the package
State's responsibility
- ·Choice and setup of the target environment (infrastructure and network)
- ·Integration with the Finnish Defence Forces' air surveillance interfaces
- ·Load and security testing
- ·Authority certifications and security audits
- ·App Store and Google Play releases
Decisions on these are made and the necessary software is implemented — on the state's chosen stack, with the package as the blueprint.
This work takes time, but a fraction of SIREN's two-year schedule (and budget). The package gives the state, or a partner of its choice, a ready foundation to build on.
Government representative? Contact Mikko directly →Why this was done
During the March 2026 drone incidents, Estonia warned its citizens by SMS. Finland did not warn. The state announced it would build an alert application — but on a timeline of nearly two years. That timeline has been justified by international comparisons (1.5–2 years elsewhere). This is not a one-application problem — it is a problem of how software is procured.
“Two years for a simple alert application is an absurd timeline when the need is, if anything, for last week.
We did not build a finished application for the state — we could not. We built what every software project should build before coding starts: a production-grade specification any AI agent platform or development team can implement. We wanted to show that an alternative way of operating is possible — not only in this project, but in many other public-sector projects.”
Mikko Laakkonen
CEO and founder, Taiga AI
“I have watched, for a couple of decades now, how the public sector procures software. In projects critical to society and security of supply, money is rarely the issue — time is. When the world changes in weekly cycles, a two-year procurement timeline is itself a security risk.”
Henri Grönlund
Chair of the Board and founder, Taiga AI
Frequently asked questions
Is HÄLYTIN the same as the state's SIREN project?+
The end goal is the same: a drone alert on citizens' phones. SIREN adds the feature to the 112 Suomi app; HÄLYTIN is a standalone implementation package that also ships with a reference implementation. The technology and architecture are independent, but the outcome for the citizen is equivalent.
If Taiga did this in a weekend, why is the state spending two years and €6.5M?+
We do not know. €6.5M is the budget of the state's broader hazard-notification development programme, of which SIREN is a part. Authorities have justified the timeline with international comparisons — similar systems have taken 1.5–2 years to build elsewhere. SIREN's scope of work may include integration and process requirements that are not publicly described. We would be interested to see them.
What was actually done over the weekend?+
Not a finished application. A production-grade implementation package: application architecture definition, technical specifications and API descriptions, threat models, DPIA, regulatory analysis, project plan, and reference implementation source code. From the package, a production application can be built an order of magnitude faster than traditionally — with any AI agent platform or a conventional development team.
What does “pro bono” mean in practice?+
The implementation package and the work done are handed to the state at no charge. Access to the Taiga platform to finish and deliver the package is included in the offer. Follow-on work, consulting and sitting in meetings are not pro bono.
Why is Taiga doing this?+
Two reasons. First, we consider a two-year timeline a security risk for Finns. Second, HÄLYTIN is a concrete example of an alternative way to operate — the package can be implemented on any development stack.
Is the package available publicly?+
No. We hand it to the Finnish state for security and regulatory reasons. If the state decides to open the package, that is the state's decision.
How can the state take the offer?+
By contacting Mikko Laakkonen or Henri Grönlund with the details on this page. Directly, without a tender.
What is Taiga?+
Taiga AI is a Helsinki-based software company building an AI software factory for regulated companies and the public sector. More: tai.ga.
