Buy-Side AdvisoryA deal you close on verified numbers, not on the seller's story.

What the Story Hides

Information asymmetry

You've seen the Confidential Information Memorandum. You've heard the founder's story. It sounds like a goldmine.

But in M&A, the difference between a successful acquisition and a million-dollar mistake usually lives in what wasn't said - whether the revenue is sticky, whether the team is staying, whether the "synergies" are real or just math on a slide.

When the Model Meets Reality

Capital at risk

Growth through acquisition is a high-stakes game. You're betting your capital and your reputation on someone else's data.

The challenge is making sure the asset performs the way you projected once the deal closes - one overlooked tax liability or an aging tech stack can erase years of expected profits.

Buying More Than a Balance Sheet

Information parity

An acquisition is closer to a marriage than a transaction. You're buying a culture, a customer list, and a set of processes.

Finding the target is only the beginning - the real work is closing the "information asymmetry" gap. The seller always knows more about the problems than you do. I level the playing field.

No strings attached

Send me the seller's CIM, model, or financials. I review the assumptions, structure, and outputs, and reply with the three findings that matter most before you submit an offer.

No automated funnel.

A successful transaction is only possible after a deep transformation of your understanding of the target. I stress-test the business model, plug the "leaks," and pressure-test every assumption the seller has presented as fact.

While you focus on the high-level strategy and cultural fit, my work goes into the inner workings of the business. My job is to give you the confidence to walk away from a bad deal, or the leverage to negotiate a better price based on hard data, not the founder's narrative.

The Process: Five Phases, One Verified Asset

Five phases, signed off step by step, so you watch the diligence take shape rather than receive a black box at close. Some phases are pure investigative work and stay on my desk; others need you in the room, your lawyer at the table, or the seller's team across it. When a step needs a skill outside mine - sector benchmarks, tax structuring, environmental review - I bring in a trusted collaborator rather than improvise.

1

Preliminary review, synergy modeling, NBO

Target analysis & deal architecture

The seller's data gets screened for early red flags, then the target modeled against your existing financials to validate that the synergies are real and not just math on a slide. From there I frame a non-binding offer with terms that protect your right to adjust as findings emerge: a clean entry that signals you are a serious, sophisticated buyer.

2

QofE, operational, commercial, legal review

Quality of Earnings & due diligence

One-time gains and accounting noise get stripped from the financials to expose the true recurring cash flow under your ownership. Customer concentration, contract stability, middle-management strength, IP ownership, employment disputes, and regulatory exposure all get audited: every risk that does not show up on a balance sheet.

3

Payment terms, earn-outs, SPA risk allocation

Transaction structuring

I design how you actually pay: balancing cash at closing with deferred payments, earn-out KPIs tied to verifiable performance, and indemnities, holdbacks, or escrow accounts in the SPA. The structure incentivizes the founder to deliver on promises and shifts the risk of anything I found in diligence back onto the seller.

4

Price chip, conditions precedent, fund transfer

Final negotiation & closing

Findings get converted into negotiation leverage: a price chip where the diligence exposed a gap, tightened earn-out thresholds where the projections looked stretched. I oversee the final signing and verify every condition precedent has been met before a single dollar moves. You become the official owner of a verified asset.

5

Earn-out tracking, KPI verification

Post-closing monitoring

If the deal includes an earn-out, the work continues. I monitor the agreed indicators against the targets set in structuring, so future payments reflect the actual performance of the asset, not the spreadsheet projection that lived only inside the seller's pitch deck.
