The email landed in Harold's inbox with a deceptively simple subject line: "Due Diligence Request — Phase One."
"Phase One." Sounds easy. Sounds like just some simple questions.
I didn't even have to open the attachment to know what was coming. But I did. Harold opened it too. We were on the phone together.
143 different due diligence requests.
The Excel spreadsheet had so many tabs at the bottom that you had to scroll right just to see them all. Eight worksheets. Nine. Ten. It kept going.
Right at the top: "Basic Information" making it seem like this was simple stuff that everyone shares. But those "basic" requests included Harold's most sensitive crown jewel information: customer lists with contact details, actual contracts, five years of detailed project margins, employee compensation history, proprietary bidding processes.
This wasn't Phase One of anything. This was the buyer's dream wish list including everything they could possibly think of that might be relevant to assess Harold's business.
And Harold's first instinct? "I've got all this stuff. I can get my employees on it. We'll just dump everything in the data room."
That instinct would have cost him millions.
The Three Fatal Detours
Before I explain how to handle this situation, you need to understand the three fatal detours that destroy seller leverage:
Fatal Detour #1: The Handshake Detour — Agreeing to negotiate with one person, dealing with specifics later, running on positive emotion. "This guy understands me." That's a detour to disaster.
Fatal Detour #2: The Data Dump Detour — Your instinct to be "transparent" by sharing everything at once. In litigation, we called this "putting the opposing party under the wave." You're not being transparent. You're shifting burden while making them think you're hiding something.
Fatal Detour #3: The Custom Detour — Getting clever with your deal structure, trading a goat for a horse, feeling good at the end of the day. The problem? Custom deals are impossible to document. Your lawyers will spend months trying to weave your goat trade into enforceable contracts.
The 143-item request? That's an invitation to take the Data Dump Detour.
The Buyer's Real Strategy
What the buyer is actually trying to do with that massive request list:
Overwhelm you with volume to make you emotional
Create urgency: "We can't give you a number until we have this"
Make you the bottleneck: "Everyone else provides this. Why are you so difficult?"
Bypass your processes to gain advantage over other buyers
Get crown jewel information while they have maximum pricing leverage
They want your most sensitive information upfront so they can tell you (when their price comes in different than competitors) that their number is "real" and the others will come down "once they find out."
It's a psychological trick. They do it every time.
The Information Waterfall: Your Defense
Your defense is a framework I call the Information Waterfall—a controlled, gated process for releasing information that maximizes competition and minimizes risk.
Level 1: NDA Lock — Before any release. Just a teaser. "Are you interested? Does this fit your profile?"
Level 2: Basic Information — Your Confidential Information Memorandum (CIM), high-level financials, strategic highlights. Gate to Level 3: An IOI with proof of funds and timeline.
Level 3: Deep Dive — Detailed financials, unit economics, anonymized customer data, some operational SOPs. Gate to Level 4: Executed LOI with exclusivity.
Level 4: Crown Jewels — Trade secrets, regulatory filings, strategic plans, the stuff you definitely don't want competitors to have.

How to Build Your Waterfall
Work backwards from the bottom:
Step 1: Identify your crown jewels. You know what they are.
Step 2: Collect your deep-dive information
Step 3: Assemble your basic information
Step 4: Create your public teaser
As you unpack this, you're building your Virtual Data Room. But most importantly, you're learning what your business looks like on paper—and discovering risks before the buyer does.
The Four Reasons for the Waterfall
Force buyers to make progressive commitments — Every time they get more information, you get more commitment. Control and momentum.
Maintain competitive tension — Everybody gets the same stuff. Level playing field. No advantages.
Protect against competitive intelligence gathering — Some buyers just want intel. They'll walk when they see your process. Let the door hit them on the way out.
Create natural checkpoints — You discover your own risks before the buyer does. When they find the same issue and you have a thoughtful response prepared, you look like a superhero.
The Outcome
My response to Karen's 143-item wish list was simple:
"Karen, thank you for your thoughtful due diligence list. However, we've agreed to only give you Level 2 information until we get APEX's IOI. Just give us a purchase price and proof of funds. APEX is getting the same treatment as all other buyers, which includes the same information and the same deadlines."
Five days later, Karen's response: "Understood. When is the IOI due?"
We went from 143 items that would have taken years to answer down to: Give us a number. Prove you have money. Show us you can close.
The result? Harold ended up with three serious bidders: $74 million, $76 million, and $70 million.
