Automated FDD vs Big-4 Advisory Firms
Big-4 FDD engagements are thorough — and expensive. For most PE/VC deals, automated analysis gives you the financial insights you need without the six-figure fee or the wait.
| Big-4 Advisory | Zenith FDD | |
|---|---|---|
| Cost | $50,000–$250,000+ per engagement | Flat software subscription |
| Turnaround time | 4–8 weeks | Hours to days |
| Depth of financial analysis | High — expert-led | High — automated + flags |
| Audit trail | Deliverable report only | Full, timestamped, repeatable |
| Scales across deals | No — re-engaged per deal | Yes — reusable workflow |
| Regulatory / expert sign-off | Yes | No |
When you still need a Big-4 firm
For large, complex transactions — especially those requiring regulatory approval, expert witness testimony, or sign-off for LPs — a Big-4 advisory engagement remains the right choice. Their name on a report carries weight in those contexts.
For the other 80% of deals: proprietary deal flow, smaller platform acquisitions, add-ons — Zenith gives your team the same financial analysis layer without the cost or timeline. Many firms use both: Zenith for initial screening and Big-4 for final sign-off on the deals that proceed.
