Provider comparison
Rapid Diligence vs Zenith Analysis
Rapid Diligence focuses on digital businesses: eCommerce, SaaS, and content sites. They run a five-component diligence approach and publish a two-tier structure, a QoE Lite and a full QoE. For an online asset, a meaningful share of the risk lives in traffic, platform dependency, and channel concentration rather than in the ledger, and they are built around that.
Side by side, on published facts only
Everything in the Rapid Diligence column is something they or a third party published. Where they do not publish a figure, the cell says so rather than guessing. Pricing and turnaround as published by Rapid Diligence and in a third-party provider roundup, 2026.

Where the two approaches actually diverge
Different asset classes, honestly. We built for businesses with bank accounts, payroll, trucks, and a filed 1120. The reconciliation problem there is proving that recorded revenue actually landed in the bank, month after month, and proving the earnings survive contact with the tax return. That is the layer we automated, and it is why our Lite tier lands below their Lite tier while running a full twelve-month cash proof rather than a sample.
When Rapid Diligence is the better call
If you are buying a content site, an Amazon FBA business, or a SaaS product, hire someone who does that all day. The questions that decide those deals are traffic durability, platform concentration, and churn, and a firm built for operating businesses is not the sharpest tool for them. That is Rapid Diligence territory more than ours.
What you get from us, specifically
A team of CFAs, ex-investment bankers, and former McKinsey management consultants who have overseen more than 800 transactions between them. Every add-back gets a written verdict of accepted, reduced, or rejected with the evidence next to it. Every month of bank activity gets reconciled to the books rather than sampled, and on a Comprehensive engagement that tie extends to the filed tax returns. The complete Excel workbook ships with the report, so your lender and your accountant can audit the work instead of trusting it.
And the report is not where we stop. You get a walkthrough of the findings when the draft lands, and we stay reachable while you negotiate, because a finding you cannot use in the room is not worth much. That advisory relationship is part of the engagement, not a tier above it.
Three flat prices, published: $299 to screen a deal before you commit to an LOI, $2,899 for a QoE Lite, $9,799 for a Comprehensive scoped to SBA SOP 50 10 8.1 Appendix 15. No hourly billing and no scope surprises.
