Legacy software modernization

The software yourbusiness runs onis getting old.I make it new again.

Slow systems, aging databases, code no one dares touch. I rebuild outdated business software into fast, secure, modern systems, with zero downtime, and a fixed-price audit before you decide anything.

Sound familiar?

Does this sound like your company?

Every audit we run starts with the same three stories. If one of them is yours, you already know why you are here.

The job ad nobody answers

You are hiring an AS400 or Navision developer. It has been open for five months. Two people applied, and both were older than the system.

The one colleague who knows

Orders live in the old system, invoices in Excel, and the link between the two lives in the head of one person who is on holiday for two weeks.

The Friday nobody plans for

It has worked for fifteen years, so nobody complains. That is exactly why nobody can say what happens on the day it finally stops.

Step one

The audit

We connect with read-only access and examine your systems the way a surveyor examines a building. You receive a plain-English report of every risk, ranked by how badly it can hurt you.

What comes after

The dashboard your old system cannot show you

Most audits reveal the same thing: the data is fine, the owner just cannot see it. We build a live cockpit on top of your existing system, read-only, in about two weeks. This one is a sample. Click it.

Your safety

How we protect your business

Your biggest worry is that someone breaks the system you depend on. Every engagement is built, from the first minute, to make that impossible.

Read-only, always

We never modify, install on, or restart a running system. Your operation cannot be affected by an audit, by design.

NDA before anything

A signed non-disclosure agreement arrives before you share a single credential. Everything we learn stays between us.

Access you control

You create the credentials and you can revoke them at any second. We tell you exactly what to share and nothing more.

Your sign-off first

Nothing is built, changed, or invoiced without your written approval. Every step of every project waits for your yes.

A note from the founder

Most IT companies want to replace your system, because replacement is what pays for their office. I do the opposite. Your system works. It just needs to stop being a mystery and a risk.

I keep Revanio deliberately small. You deal with me directly, I answer within a business day, and every price is fixed before work starts. If an audit shows your setup is healthy, the report will say exactly that.

Dave

Founder, Revanio

Fair questions

Is it safe to give you access?
We work with read-only credentials that you create and can revoke at any moment. We never install anything on a production system, and we sign an NDA before receiving anything.
Which systems do you handle?
Old ERPs, custom-built software, AS400 and iSeries environments, Navision and Exact installations, Access and Excel constructions that grew into critical tools. If people are scared to touch it, it qualifies.
Why is the audit paid and not free?
A free audit is a sales trick with a report attached. A paid one obligates us to find things worth €590 of your time, and it means we work only with companies that take the problem seriously.
What if our system is too old or too strange?
There is no such thing. The stranger it is, the more valuable it is to have it documented before the one person who understands it retires.
Who actually does the work?
You work directly with the founder. No account managers, no handoffs to a team you have never met.
We are not in the Netherlands. Can we still order?
Yes. We start in the Dutch market but work with companies across the EU. Everything runs remotely and in English.

Know exactly what you are running on.

One fixed price, one report, two days. The worst outcome is a document proving your systems are healthy.
