RocketX helps scale-ups and PE-backed companies build scalable commercial engines. With a team of 60 in Amsterdam, RocketX supports high-growth businesses such as OneFlow, Deel, Getir, YoungOnes, TicketSwap, Zenjob and Flink with sales strategy, go-to-market execution, and revenue acceleration.
Behind that growth sits a complex finance operation with six entities, including one abroad. Fractional CFO Rudolf Maas Geesteranus needed fast, reliable insights into consolidated performance – without losing time in Excel or scattered sub-administrations.
As RocketX scaled, manual consolidation in Excel quickly became too time-consuming and error-prone. Tools provided by the accountant didn’t offer the flexibility or transparency needed. Managing six entities - including an administration in Greece - meant that even receivables tracking became fragmented.
“I simply lost grip,” says Rudolf. “What I needed was one central platform that could give me instant clarity, without days of manual work.”
On a Friday morning, Rudolf decided to “just switch it on.” By the afternoon, all six entities were connected and consolidated. Within hours, Finstack delivered what previously took days: a reliable, automated consolidation model with real-time data.
Rudolf mapped the chart of accounts himself, created reporting structures, and gained instant visibility on P&L, balance sheet, cash flow, suppliers and working capital. Even the Greek entity, previously outside the group view, was integrated seamlessly.
Finstack has become Rudolf’s daily tool across all the companies he supports as fractional CFO. With one login he can consolidate, drill into details, and delegate ownership of receivables and costs to business managers.
