Buying ten companies was the easy part.

Buying ten companies in three years was the easy part.

Anyone with a calculator and patience can buy. The price is negotiable. Due diligence is craft. Lawyers write the contracts.

The hard part comes after.

Patronas, Fixhub, DSER, MiFID Recorder, Fundsaccess, Fundhero, etops.

Seven brands. Ten sites in five countries. Three hundred people. One platform.

Germany, Switzerland, Luxembourg, Georgia, Slovakia. Dresden, Görlitz, Freiburg, Munich, Kiel, Nuremberg, Bratislava.

It ended in an exit to Pollen Street Capital.

What I learned contradicts every buy-and-build deck I have seen.

The synergies are not in procurement. They are in technology. And only once everyone truly works on one system — not seven systems with a shared report on top.

This is where most roll-ups fail:

• You buy revenue and get an organization thrown in. The organization is what you actually bought.
• Every brand you keep costs margin, permanently. Keep only the ones that demonstrably sell.
• Integration is not a project after closing. It is the condition for buying at all.
• If you cannot integrate the first site in six months, you will not integrate the tenth.

Across borders, this counts twice. Five legal systems, five work cultures, one system.

The return on a roll-up is not made at purchase. It is made in integration.

I am doing it again right now. Different industry, same pattern.

Who here has run a roll-up across borders — and where did it get stuck?
