Steady, precise software.

Venusoft is a Stockholm studio building specialised tooling for regulated industries — railways, energy, finance. We make software the way an engineer makes things: carefully, and once.

Flagship
product.

We don't only consult — we ship. Our flagship platform serves engineers and compliance teams working with European Railway Agency standards.

Railway standards, finally searchable.

ERA Standards is an AI-assisted research platform for engineers, assessors, and compliance teams working under European Railway Agency rules. Natural-language search across thousands of pages of TSIs, EN standards, and notified national technical rules — with citations you can trust.

Capabilities,
focused.

A small studio working at the intersection of regulated domains and modern software. Below: the disciplines we keep close at hand.

— 01
Domain-specific search & RAG
Retrieval-augmented systems for technical corpora — standards, regulations, internal handbooks. Citation-grounded, evaluated, built to be trusted in audit-bearing contexts.
— 02
Compliance tooling
Internal platforms for teams operating under EU regulatory regimes. Versioned data models, traceable workflows, defensible records.
— 03
Data engineering
Pipelines that turn messy regulatory PDFs, spreadsheets, and legacy databases into queryable, structured information.
— 04
Bespoke product builds
End-to-end product development for niche audiences — from quiet internal tools to flagship platforms. We code, design, ship, and stay around to refine.
— 05
Cloud architecture
Pragmatic cloud setups built for predictable cost, traceable access, and long horizons. Boring infrastructure, by design.
— 06
Technical advisory
Reviewing architectures, vendor proposals, or internal tooling roadmaps. Brief engagements where a careful outside read is more useful than a long deck.

How we
work.

A short, honest read on how we build — what we commit to, and what we don't.

We build software the way an engineer would build something that has to last — with attention to materials, tolerances, and the long maintenance horizon.
A note from the studio
i.
Small by choice.
Senior-only, intentionally lean. The person scoping your project is the person writing the code.
ii.
Domain before stack.
We learn your standards, your constraints, your acronyms. Tools come second; understanding the problem comes first.
iii.
Built for ten years.
No clever frameworks-of-the-month. We choose stacks that will still be maintained — and maintainable — in a decade.
iv.
Honest pricing.
Fixed-scope where we can, transparent time-and-materials where we can't. No surprises in the invoice.

Have a problem
worth solving?

We take on a small number of engagements each year — partnerships more than projects. If your work lives in a regulated, technical, or under-served corner of software, we'd like to hear about it.
