What happens in the first call?

30 minutes. You explain your situation, I ask questions. No pitch, no pressure. If we're not a fit, I'll tell you.

What does a project cost?

Projects start from €10,000. For more complex projects, we begin with an analysis phase (from €2,500), which is credited toward the project. This gives you a binding price and me a clear picture. Consulting is billed on a daily basis (€1,800/day).

How long does a project take?

4-8 weeks typically. Complex platforms: 2-3 months. Realistic timeline upfront, delivered.

What if the project doesn't work out?

Fixed price means: the risk is on me. You pay for results, not my time. If something doesn't work, we fix it.

Can you maintain the software afterwards?

Yes. Many clients keep me for ongoing maintenance. Or I hand over everything documented to your team.

What if we're not a fit?

The first call is free. If I'm not the right person, I'll tell you and recommend someone who might be.

When do I need consulting vs. custom software?

Consulting: when you're evaluating vendors, planning a migration, or need a tech strategy. Custom software: when off-the-shelf doesn't fit. Often, one leads to the other.

Can you help choose the right software vendor?

Yes. I evaluate options against your requirements, cut through marketing, and help negotiate. No vendor commissions. My advice is independent.

Real estate sales platform for the Relago Group

The Starting Point

A real estate company sells apartments as investment properties through external consultants. The sales process ran on WhatsApp, email, and multiple Excel spreadsheets. One employee worked full-time maintaining documents in Dropbox and coordinating with consultants. Commissions were calculated manually – payments went to wrong IBANs because clients had provided multiple accounts. Reservations were managed through back-and-forth messages. Nobody knew at a glance which apartment was reserved, sold, or still available. As volume grew, it became clear: this won't scale.
