Advisory firms, private equity funds, investment banks and family offices use Zion Advisor as their execution layer — across the Nordics, UK, Europe, Middle East and India.
Why Zion Advisor
Most offshore FDD providers staff a junior pyramid and sign off at the top. We do not. Every engagement is run by people with Big 4 transaction backgrounds, with a senior review gate before anything is delivered.
Senior-led, not pyramid
Your databook is built by people who have run live transactions, not by juniors learning on your deal. A senior review gate before delivery catches what a junior build misses.
SIE-native for the Nordics
Sweden is our priority market. We work from the SIE4 export rather than a reformatted spreadsheet, and we know where K2 and K3 diverge in ways that move EBITDA. Sweden in detail
48–72 hours to first cut
On a fixed-project engagement, you have a first-cut databook inside 72 hours. If the deal is going to fail on the numbers, it fails early and cheaply.
No minimum commitment
Start with one deliverable on one deal. Our fixed-project model carries no minimum, no retainer, no long-term tie-in. How engagement models work
What we do
Financial due diligence and the databooks that underpin it. We cover the full deal lifecycle — from buy-side QoE to sell-side readiness to post-merger integration.
Financial Due Diligence
Quality of earnings, adjusted EBITDA, revenue quality, working capital and net debt.
M&A Databooks
Linked Excel schedules with visible formulas. Every figure traceable to source.
Financial Modelling
Operating models, scenario analysis and investor packs built on reconciled historicals.
AI Finance Automation
Automated data loading, reconciliation and schedule building — so the analyst starts on analysis, not data entry.
See a real databook
A complete financial due diligence databook, built on synthetic data. Ten annotated pages covering the adjusted EBITDA bridge, working capital peg, net debt and debt-like items — plus the full 24-page PDF extract to download, no email required.
