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 Intelligence is a working platform for engineers, assessors, and compliance teams across European rail. Three modules — Enquiries, Requirements, and Compliance — sit on top of an indexed corpus of ERA documents, TSIs, ERTMS SUBSETs, EN 50xxx, EU Directives, UIC leaflets, and national rule sets (DIN, NF F, RFI, RATO, BOStrab, RIS, NSAI). Ask in any of nine EU languages. Answers cite section numbers, table references, and figure numbers. Requirements export as ReqIF for DOORS, Polarion, and Jama; compliance findings come back as gap matrices.

Does RATO-2 apply to all high-speed lines?
ERA STANDARDS · Standard ✓ high confidence 🇫🇮 Finland
No, RATO 2 does not apply to all high-speed lines. The guidelines in RATO 2 apply to railway lines with speeds under 250 km/h1. For high-speed lines operating at speeds of at least 250 km/h, additional requirements are specified in section 2.6.9 of RATO 21.

RATO 2 Radan geometria
2  RADAN GEOMETRIA
Ratateknisten ohjeiden (RATO) osa "Radan geometria" sisältää perusteet Suomen valtion omistaman rataverkon raiteiden geometrian suunnittelua varten.
Ohjeet koskevat ratoja, joiden nopeus on alle 250 km/h. Vähintään 250 km/h nopeuden suurnopeusratojen lisävaatimukset on esitetty kohdassa 2.6.9.
— What we do · 02

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.
