How a partnership works, in numbers
$25k to $500k
per partnership, depending on document types, complexity, quality of analysis and page count
1 to 3 hours
of your time in total. A quote needs 2 or 3 samples and a short inventory of the archive
7 to 10 days
from intro call to payout by wire, once the documents are reviewed and accepted
You receive a quote for the whole archive before you send it. All we need for that is 2 or 3 samples, anonymized on request, and an inventory table of what the archive contains.
What we license
Four families of financial documents qualify. Long form analysis comes first.
01
Deal and process materials
- CIMs and CIPs, authored or received on past processes, including real estate OMs
- Management presentations
- Process letters, teasers and bid instructions
- Term sheets, LOIs, fee letters and NDAs from the deal folder
- Fairness opinions and board decks
02
Investment committee and research
- IC memos and IC decks, first round or final
- Initiation style write ups and long form theses
- Sector deep dives, landscape and market sizing reports
- Earnings reviews and thesis updates with real analysis
- Valuation reports and fairness analyses
03
Credit and financing
- Lender and financing presentations under 50 pages
- Rating agency decks under 50 pages
- Credit memos and credit committee papers
- Financing and credit agreements, debt term sheets and commitment letters
04
Fund and diligence materials
- QoE reports, diligence reports and financial DD summaries
- Commercial and market due diligence studies
- LP updates, investor letters and annual meeting decks
- PPMs, offering memoranda, LPAs and side letters
- Fund marketing decks, pitchbooks and completed DDQs
Not an exhaustive list. If a document carries real financial analysis, it is likely a fit. Full archives earn more than hand picked files, because the drafts, models and call notes around a deal are what the research needs. Native Word, PDF and PowerPoint files count. Scans and emails do not.
Process
Seven steps from NDA to payout. You know the price before you send the archive.
- 01
NDA
We sign a mutual NDA before anything is shared. It covers the samples and everything that follows.
- 02
Samples
You share 2 or 3 sample documents, anonymized on request, so we can see what the collection looks like.
- 03
Fit check
We assess whether the material is what we are looking for and give you feedback.
- 04
Sizing
You give us a view of the collection, file count and types, through screenshots, a short walkthrough or an AI prompt run on your own machine.
- 05
Quote
We quote the total deal size for the whole archive. Nothing beyond the samples has left your machine at this point.
- 06
Agreement
Once you accept the price, we sign the licensing agreement and you send the files through Google Drive or Box.
- 07
Payout
Payment by wire, usually within 10 days of the intro call.
Your side
1 to 3 hours in total, mostly sharing samples and sizing the archive.
Our side
Assessment, quote, redaction and licensing, at no cost to you.
Redaction and security
Every document is anonymized, verified, and never published.
- 01
Automated screening
Proprietary software removes client, counterparty and personnel identifiers, deal code names, logos and document footers.
- 02
In house review
Every redaction is checked by full time financial professionals who previously worked at investment banks and PE funds.
- 03
Residual PII check
Each masked page is checked again for text and visual residue before a document is accepted. A fail sends it back.
- 04
Accepted and licensed
Only documents that pass are licensed. They are never published and are used only for research and training.
Need to know access
Access is limited to the people who require it for review.
License scope
The license applies only to accepted materials. Rejected materials are never used.
Verified deletion
Rejected materials are securely deleted within 30 calendar days, verified through system records and periodically audited.
What partners say
We've been working with Meridian for almost a year. What sounded like an unconventional offer turned out to be a seamless experience. Payment is always timely, and the team is a pleasure to work with.
Meridian is a great partner to do business with. They always respond almost instantly and keep their promises.
About $1m was paid out to partners in August and September 2026. We never reveal the identity of our partners without permission, and we are happy to connect you with past partners who have agreed to act as references. Testimonials predate our renaming from Meridian and are quoted verbatim.

Common questions
Do I have to share the full archive before I know the price?
No. A quote only needs 2 or 3 samples and an inventory of the archive, which you can produce with an AI prompt on your own machine. The inventory contains no confidential information.
Will our firm or its clients be identifiable?
No. Client and counterparty names, matter numbers, deal code names, bank details, registry numbers and similar identifying information are removed before a document is accepted.
What happens to the documents?
Accepted materials are used only for research and training. They are never published. Rejected materials are deleted within 30 days.
Can I see the redacted versions?
Yes. We can send you a selection of the redacted versions of your documents.
Who is eligible?
Firms and professionals who own their documents or have the right to share them, consistent with any confidentiality obligations they owe. All submissions go through an eligibility review.
