Engineering system for requirements and validation: Know
what's missing.
Before
it costs you.

You send us a request, a tender or a specification. You get back what is open, a test plan with cost, and every requirement linked to its evidence.

RAIL · AUTOMOTIVE · ENERGYPROCESSED IN THE EUREPLY IN 1 WORKING DAY

The requirements system for modern engineering.

One chain from customer request to evidence. Start wherever your work is today.

PROJECT START · REQUIREMENTS MANAGEMENT

Run requirements from day one.

Drop the specification, the tender and the customer e-mails. Cevelar turns them into requirements with their source, gives each team its part and shows coverage as it grows. Next to your requirements tool, or instead of the spreadsheet.

REQUEST · TENDER

Answer a tender.

Every open question, with its page. Your answer goes out in days, not weeks, while the request is still warm.

TEST PLAN · COST

Plan validation.

See what drives the cost and what you can reuse from earlier programmes, before you quote.

DEVELOPMENT STATUS · AUDIT

Trace every step.

The whole development status along the chain, from request to evidence. Traceable both ways, at any time.

FROM OUR CUSTOMER CONVERSATIONS

Engineers tell us the same thing.

In their own words, from calls with rail, automotive and electronics teams. Translated from German.

AUTOMOTIVE · ENGINEERING
“Wow. Finally something built by engineers, for engineers.”
Engineering, automotive supplier
AUTOMOTIVE · TESTING
“A clean link back to the requirements and a clear view of the test cases for each one. Right now we have none of that.”
Head of testing and validation, automotive supplier
POWER ELECTRONICS · PRESALES
“One person, two full-time weeks, doing nothing but estimating.”
Managing director, power electronics manufacturer
RAIL · TENDERS
“A gap in the specification comes back to bite you once you have committed. Then the rework gets expensive.”
Product lead, rail infrastructure
AUTOMOTIVE · SYSTEM ARCHITECTURE
“If the requirements have gaps, the test plan can be as good as you like. It gets expensive.”
System architect, automotive supplier

FAQ

Questions about Cevelar.

What is Cevelar?

Cevelar is an engineering system for requirements and validation. It reads customer requests and specifications, finds what is open or missing, derives test plans with cost and links every requirement to its evidence. Engineers review the results where judgement is needed.

What is a requirements gap?

A requirements gap is a requirement without a test that proves it, a test without a source in the specification, or evidence that no longer matches the current edition of a standard. Gaps usually surface at the audit. Cevelar shows them while they are still cheap to close.

Which industries does Cevelar work with?

Cevelar works with suppliers and engineering service providers in rail, automotive and energy, across Germany, Austria and Switzerland.

Does Cevelar replace our requirements management tool?

No, Cevelar works next to your requirements management tool. It covers the steps around it: reading the customer’s documents, and checking that every requirement has a test and evidence behind it.

How is Cevelar priced?

The platform is a yearly subscription per team. Engineering mandates and test campaigns are scoped and quoted per programme. The battery passport readiness check is a fixed price of €3,900 net.

Where is our data processed?

Your data is processed in the EU. Only your team and the Cevelar engineers on your project see your documents, and they are never used for other customers.

Who is behind Cevelar?

Cevelar was founded in Berlin in 2026 by Nils Flagmeier and Max Beitler. Nils brings eleven years of testing and validation in battery and automotive programmes; Max builds the platform.

How do we start?

Start with a call. We look at one real request or specification of yours, agree on what a good result is, and you try Cevelar on that document.

Coverage is not a feeling.

Bring one document. We show you what is missing.
