How to Close a 100 Million Dollar Deal

Why a 100 million dollar deal is different

At USD 100M the person across the table is rarely one person. It is a board, an investment committee, a family office, or a holding group with its own advisors. They are not only assessing your deal. They are assessing you: whether your company can survive their diligence, whether your numbers hold, and whether the people they meet can actually commit.

Large deals are hard even after they sign. A 2011 Harvard Business Review article by Clayton Christensen and colleagues noted that companies spend more than USD 2 trillion a year on acquisitions and put the M&A failure rate between 70% and 90%. My focus here is the earlier failure, the one nobody counts: deals that die before the signature because one side was not ready.

Big deals rarely die on price. They die on readiness.

How to prepare your company for a 100 million deal: the readiness checklist

This is the core of my book, The Deal Architect. Before you approach a principal, check seven things. If any one fails, fix it first.

Area	What "ready" looks like	Red flag that kills deals
Governance	Clear board or decision structure, minutes, shareholder agreement, clean ownership records	Founders disagree on who decides
Data room	Organized folders: corporate, financial, legal, commercial, people, assets, ready before anyone asks	Documents sent one at a time by message, on request
Numbers	Accounts reviewed by professionals, a model that ties to them, assumptions written down	The model and the accounts disagree
People	A named team, cover for key people, advisors engaged	Everything depends on the founder
Partners	Lawyers, auditors and licensed firms lined up for regulated parts of the deal	"We'll find a lawyer when there's a term sheet"
Authority	Who can sign on each side is known and documented, with resolutions ready	The person across the table cannot sign
Timeline	A dated plan: 90 days to a decision, 90 days to execution	"We'll move when they're ready"

Governance and authority come first

Of the seven, these two kill the most deals I see. A principal will forgive a messy spreadsheet. They will not forgive discovering, three months in, that your co-founder never agreed, or that the counterparty they have been negotiating with needs a chairman's approval nobody has asked for. Confirm authority on both sides in the first meeting, politely and directly.

The data room is your credibility

A complete data room before the first serious conversation tells a counterparty that you respect their time. It also protects your timeline, because diligence questions get answered in days rather than weeks.

The founder cannot be the whole company

John Warrillow's Built to Sell makes the point well: buyers hesitate when a business cannot run without its owner. The same applies to partners and strategic investors at USD 100M. Show them a team, not a person.

What a principal checks in the first meeting

Serious principals rarely say what they are testing, but in my experience the first meeting answers four questions for them:

Is this person straight with me? Clear answers, including "I don't know yet, I'll confirm by Thursday", beat polished ones.
Can they decide? If you have to check with someone on every point, they will wonder who they should really be meeting.
Is the company ready for my diligence? They will ask one hard question early to find out.
Does this solve a problem I actually have? A deal framed around their priorities moves. A deal framed around your need for money stalls.

Prepare for those four questions and the meeting becomes a working session instead of a pitch.

The 90/90 Method: how big deals actually close

The 90/90 Method gives a large deal two fixed windows. Deadlines matter because large deals do not usually die in a single moment. They drift.

Days 1 to 90: get to a decision

Complete the readiness checklist and close the gaps.
Identify the principals who can actually decide, and earn the first meeting by solving a problem for them.
Put an engagement letter and NCNDA in place before the first introduction. This is Law II of my Laws of the Desk: engagement first.
Agree the outline structure: who carries which risk, who controls what, and how and when each side gets paid.
Reach a clear yes or no. A fast no is a good outcome. It frees you for the next deal.

Days 91 to 180: execute

Turn the outline into documents with licensed lawyers and advisors.
Run diligence from the data room you already built.
Manage conditions, approvals and signatures against dated milestones.
Plan delivery before closing, so the first 90 days after signature are already mapped.

Ninety days to decide, ninety days to execute. Anything without a date is a wish.

How to close big deals: the negotiation itself

At this size, structure usually matters more than price. Two offers with the same headline number can be completely different deals once you look at timing of payment, conditions, control and who carries risk if things go wrong.

Negotiate interests, not positions.Getting to Yes remains the best framework: understand what the other side needs, and know your best alternative to a negotiated agreement before you walk in.
Use structure to bridge gaps. Staged payments, performance-linked terms and joint ventures can close a gap that price alone cannot.
Keep the principals talking. When lawyers take over, momentum drops. Schedule principal-to-principal check-ins through execution.
Never hold the money. Law III of my Laws of the Desk: coordinator, never custodian. Funds move through licensed, regulated channels, never through me.

Seven reasons big deals die

No authority across the table. Long chains of intermediaries, none of whom can sign.
Numbers that do not reconcile. The first diligence question exposes a gap, and trust goes with it.
A data room built after the term sheet. Weeks are lost, and the counterparty starts to wonder what else is missing.
A founder-dependent business. The counterparty is buying a person, not a company.
No engagement terms. Introductions happen without an engagement letter or NCNDA, and the deal is circumvented or stalls in confusion.
Timeline drift. No dated plan, so the deal loses priority to whatever is urgent this week.
Ego about price. One side anchors on a number and refuses to explore structure.

How to close a million dollar deal (the same steps, smaller)

A USD 1M deal follows the same logic at a smaller scale. You may be the decision maker on your side and the documents will be shorter, but the questions are identical: are you ready, is the person across the table able to sign, is the structure clear, and is there a date? If you learn the discipline at USD 1M, USD 100M becomes a question of scale, not of a different game.

Proof: what this looks like on my desk

These are not theories. In 2026 I secured a USD 1B exclusive sales mandate for two Dubai towers, an 80+ storey tower and a 50-storey tower. I hold a written global mandate (2025 to 2027) to represent and negotiate for Abdulla Bin Mujren Investment Group, a Dubai holding group of 14 companies.

As Board Director and founder of AERC, a waste-to-energy consortium of about USD 500M project value designed for 7,500 tonnes a day, I have seen the consortium agreements signed while funding and launch are still pending. That is a reminder that signing is a stage, not the finish line. As Head of Alliances and Growth at Galaxy Weblinks, I have signed USD 30M of software deals. Before Dubai, I spent 14+ years in Toronto real estate and closed USD 300M in personal sales between 2010 and 2024. In total: 191 deal files across 11 sectors. See all projects or read about me.

Relationships are the asset. Signatures are the proof.

Strategic advisory and introductions only. Not investment, legal or tax advice, and not an offer of securities. Regulated activities are handled by appropriately licensed firms.

Frequently asked questions

How do you close a 100 million dollar deal?

Start with readiness: governance, a complete data room, reconciled numbers, a real team, licensed partners, documented signing authority and a dated timeline. Then use the 90/90 Method: 90 days to reach a clear yes or no with principals who can decide, and 90 days to execute through documents, diligence and signatures. Negotiate structure, not only price.

How long does it take to close a 100 million dollar deal?

Every deal is different, and regulated or cross-border deals can take longer. The 90/90 Method sets a working target: 90 days to reach a decision and 90 days to execute, so roughly six months from serious engagement to signature. The point of the deadline is to stop drift, which kills more large deals than any single objection.

How do I prepare my company for a 100 million deal?

Check seven areas before you approach a principal: governance, data room, numbers, people, partners, authority and timeline. Make sure the founders agree on who decides, the accounts and model reconcile, the business does not depend on one person, and licensed lawyers and auditors are lined up. Fix every gap before the first serious meeting.

What should be in a data room for a large deal?

At minimum, organized folders for corporate records, financial statements and models, legal agreements, commercial contracts, people and organization, and key assets. The exact list depends on the sector and the deal, and your lawyers should confirm it. What matters most is that it is complete before the first serious conversation, not assembled after a term sheet.

Why do big deals fall apart?

In my experience the most common reasons are no real authority across the table, numbers that do not reconcile, a data room built too late, a business that depends on its founder, introductions made without engagement terms, timelines that drift, and one side anchoring on price instead of exploring structure. Most are preventable with preparation.

How do you close a million dollar deal?

The same way, at smaller scale. Confirm you are ready, confirm the person across the table can sign, agree a clear structure covering risk, control and payment, and put a date on every step. You may be the decision maker yourself and the documents will be shorter, but the discipline is identical, which is why smaller deals are good practice.
