CASE STUDY · FIRMA.DE
If growth means hiring, your systems are broken.
2x the volume your team handles, or I keep building for free until you get there.
Three bottlenecks that slow you down
What each one costs today, and what it looks like fixed:
Software your team works around
Today: Off-the-shelf tools force the job into their menus. People keep side spreadsheets to get around them.
Fixed: Programs, screens and workflows shaped around how your team works. They adapt as the work changes.
A website that doesn't bring in work
Today: Three businesses get the same enquiry. The fastest reply wins, not the cheapest. You reply hours later.
Fixed: Customers find you in Google and in AI answers. Every enquiry gets a reply within minutes, day or night.
Data spread across too many tools
Today: Five tools, five different numbers. Every month someone rebuilds the report by hand.
Fixed: All your data flows into one place, automatically. Dashboards show the real numbers, live.

Hi, I'm Mircea.
Mircea Preotu · Founder & Operator. Every task goes through me. (LinkedIn)I've been shipping software for twenty years, mostly for process-heavy German businesses, and I've been CTO of three startups.
For years I was the CTO of firma.de, Germany's largest company formation platform. Rebuilt operations around standardisation and automation across sales, fulfilment and finance, all working as one team.
Now I do the same for lean companies that need the output of bigger ones without the headcount. I decide what gets built, my AI agents carry out the execution, and I check every result before it reaches you.

Services I provide
Six services, from the website to the back office.
Replatform
Software your team works around.
If a task your team repeats every day takes thirty clicks instead of one, the software is broken. I rebuild the system around how your team uses it: the screens people open most come first, repeated steps run as one action, and information moves between tools without anyone retyping it.
- Screens and defaults ordered by what people do most
- Repetitive tasks cut down to a single action
- Data migrated with its history and checked against the old system
Websites & Lead Capture
Your website doesn't bring in work.
A site nobody finds, that loads slowly and hides the quote form, costs you enquiries every week. I rebuild it as one site your team can edit, keep every ranking you have, and wire the enquiries into the systems behind it.
- One site for all your brands, with every page that ranks today keeping its place in Google
- A site your team edits without calling anyone
- Pages structured for search and for AI answers
Faster Replies
Deals lost to a faster reply.
The business that answers first usually gets the job. I set up a system that answers every enquiry within minutes, day or night, qualifies it, and hands it to the right person with the conversation attached.
- An AI assistant that answers in minutes and hands over to a person
- Qualification questions answered before anyone on your team looks
- Routing to the right person, with the context attached
Client Onboarding
New clients wait days to get started.
Onboarding that runs on emails, PDFs and manual checks makes every new client wait. I build a platform workflow that collects the data once, checks it automatically, and moves each client to the next step without anyone chasing.
- A client portal where clients upload documents and answer questions once
- Data collected in structured forms and checked automatically
- Status visible to the client and your team at every step
Data Systems
Nobody trusts the numbers.
When reports are put together by hand and the real numbers live in one person's head, every decision starts with rebuilding the spreadsheet. I connect your tools into one source of truth, so every report comes from one place.
- An inventory of every tool, what data lives where, and which copy is right
- One home per record type: customers, deals, invoices, tickets
- Every tool updated within minutes of a change
Technical Leadership
Tech decisions with nobody senior in the room.
You want to improve, but the skills aren't in-house. I work as your fractional CTO a few days a month: I review the architecture, judge agency quotes, and make the build-or-buy calls with you.
- Architecture and system design
- Build-or-buy and vendor decisions
- Second opinions on agency quotes
WHAT CLIENTS SAY
“It has been a true pleasure working with Mircea for over nine years as the external CTO at firma.de. Throughout this time, he was responsible for our entire IT landscape and infrastructure, while also leading the development of our founder dashboard. No matter the challenge, he was always available, approachable, and ready to help. Working with him was not only highly productive but genuinely enjoyable.”
