Operator-Led Buy-Side
M&A Advisory
Most buy-side diligence is produced by teams who will never be accountable for the plan they validate. They model the synergies, flag the risks, hand over the report, and leave before the first quarter after close. The gap between a diligence pack and an operating reality is not an information gap. It is an accountability gap, and it shows up in the same places on almost every deal.
Arete Ventures works only with the buy side: general partners, limited partners, family offices, sovereign funds, and long-only public market managers across the US, UK, EU and the Middle East.
Why Buy-Side Diligence Misses the Same Things
Three blind spots that recur deal after deal. All three are downstream of who wrote the report and what happens to them after signing.
A transaction services team is trained to reach the right answer analytically. An operating partner has been accountable for producing one. Both are useful. The distinction matters most when the open question is execution risk rather than market structure, which on a mid-market deal it usually is.
Three failure modes recur, and each one is invisible to a process that ends at signing.
The plan assumes a management team that does not exist yet. Diligence tests whether the plan is achievable. It rarely tests whether the people currently in the building can achieve it, or how long it takes to replace the ones who cannot. That question decides the first year of the hold.
The synergy model is priced at the seller's cost base. Integration costs are estimated by people who have never carried an integration. The number that matters is not the synergy. It is the cash and management attention consumed before the synergy arrives, and how much of the thesis is still standing when it does.
The downside case is a haircut, not a scenario. Trimming the base case by a fixed percentage is arithmetic. Underwriting what the business actually looks like when the top three customers renegotiate at once is a different exercise, and it is the one that determines whether the capital structure survives.
We look for these because we have been on the receiving end of reports that missed them.
What We Do on a Buy-Side Mandate
Five workstreams, ordered by where deals actually lose money rather than by where diligence conventionally starts.
Diligence Written From the Owner's Side
Commercial and operational diligence built around one test: what would have to be true for this plan to work, and who inside the business is going to make it true. That means customer concentration and contract quality rather than revenue growth, cost-to-serve by account rather than blended gross margin, and an honest read on organizational capacity to absorb change while still running the business.
Our background is fifteen years as an operating partner at a San Francisco private equity firm, across technology and clean energy portfolio companies. We have carried plans we did not write, in companies we did not build.
Public-Market Pricing on a Private Target
We advise long-only public market managers in the US alongside our private markets work. That cross-over matters more than it sounds.
A private target is eventually sold into a market that prices on public comparables, trading multiples, and sector sentiment that has nothing to do with your DCF. An advisor who only works in private markets prices the entry. An advisor who watches the public comp set can tell you what the exit market is likely to pay, and whether the multiple you are underwriting has ever actually been paid for a business with these characteristics.
That is the difference between a valuation and an exit view.
Distressed and Underperforming Targets
Distressed diligence is a different discipline and most teams run it as a discounted version of the normal one, which is where the losses come from. The questions change: whether the business is loss-making because of structure or because of decisions, how much liquidity the first ninety days consume, which liabilities travel with the asset, and whether a viable business exists at materially lower revenue.
This is work we have done as principals rather than as advisors, acquiring and reviving operating and distressed assets inside a PE portfolio.
Cross-Border Execution
Deals across the US, UK, EU and Middle East carry regulatory, tax and structuring complexity that varies by jurisdiction and changes without notice. We work this as an input to deal structure rather than a compliance checklist bolted on before signing, and we bring in specialist counsel rather than pretending to replace it.
The First Hundred Days
Deals lose value in the two quarters after close more often than in the diligence that preceded them. We build the post-close plan during diligence rather than after it, because the decisions that set the ceiling for the whole hold (which systems survive, who reports to whom, which synergies have a named owner and a date) get made in a window where nobody has time to think.
Where the work continues into sustained operating change, that sits with our Performance Improvement Advisory. Where the question is fund architecture rather than a single transaction, see Private Equity & Venture Capital Advisory.
Who We Work With
Client | What they bring us |
|---|---|
Long-only public market managers | A private or take-private situation that needs an operator's read alongside the market view |
Sovereign and institutional funds | Cross-border acquisitions where structure and execution risk sit in different jurisdictions |
Limited partners and family offices | A co-investment they have to underwrite independently, on a short clock |
PE general partners, mid-market | A platform or bolt-on where the operating thesis needs testing by someone who has run one |
01
The market was pricing the core business. We found an emerging platform it was barely pricing at all.
“Is this an investable technology platform inside an established company, or a speculative science project that the market is overvaluing?”
What we found. The emerging business was early, but the underlying technology was not dependent on an unproven scientific breakthrough. We traced the process architecture, equipment partners and field-deployment pathway, then tested the economics against the physical realities of gas treatment, liquefaction, modular construction and end-market demand. The more important finding was that the market was largely valuing the company through its established LNG assets while giving limited credit to an emerging distributed-energy platform with potentially attractive capital efficiency.
What we did. We separated technical feasibility from management's commercial assumptions. That meant testing unit economics, deployment timelines, feedstock availability, regulatory drivers, customer adoption and the credibility of management's return-on-capital claims. We also examined where the technology could fail: gas composition, utilisation, logistics, offtake and the gap between successful demonstration and repeatable commercial deployment. The work gave the investor an independent operating view alongside conventional public-market research.
The hard part. The investment question changed as the share price rose. At approximately $27 per share, the issue was no longer whether the original investment had worked. It was whether the remaining upside still justified holding the position. Our view was that the underlying operating and strategic case had not yet been fully reflected in the valuation, and we advised the investor to remain invested.

The valuation worked in the model. The exit multiple did not exist in the market.
"Are we paying a defensible price for this business, or are we relying on the exit market to validate the entry?"
What we found. The operating plan could support the forecast EBITDA, but the investment case required the business to exit at a multiple the relevant public market had rarely paid for companies with its growth rate, margin profile and customer concentration. The risk was not primarily in the DCF. It was in the assumption that operating improvement would automatically translate into multiple support.
What we did. Rebuilt the comparable-company set around the characteristics public-market investors actually priced, rather than sector labels alone. We separated EBITDA creation from multiple expansion, tested the deal under lower public-market valuations, and identified the operating milestones the company would have to reach before a premium exit multiple became defensible.
The hard part. A plausible operating plan can create false confidence in valuation. The investment team had to distinguish between value the company could create itself and value that depended on the market still paying the same multiple several years later.

Frequently Asked Questions (FAQs)
Transaction services validates the numbers and hands over a report at signing. A buy-side advisor with operating accountability tests whether the plan can be delivered by the people who will have to deliver it, and stays engaged through the period after close where most value is actually lost.
Operational due diligence examines whether the business can produce the plan, rather than whether the plan is arithmetically sound. It covers customer concentration, cost-to-serve by account, management capacity, systems, and how much cash and attention integration will consume before any synergy arrives.
The questions invert. Instead of testing the growth case you test survivability: whether losses are structural or decision-driven, how much liquidity the first ninety days consume, which liabilities transfer with the asset, and whether a viable business exists at materially lower revenue.
Use both, for different questions. Big Four transaction services is built for financial, tax and regulatory validation at scale. An operator-led advisor is built for execution risk: whether the management team can carry the plan, and what the first hundred days actually cost.
Because the eventual exit is priced by that market, not by your entry model. Checking whether the multiple you are underwriting has ever been paid for a business with these characteristics is the difference between a valuation and a defensible exit view.
Before the indicative offer, not after exclusivity. By the time a deal is in confirmatory diligence the price is largely set and the advisor's role narrows to documenting risk rather than repricing it. The work is worth most when it can still change the number.
Before You Appoint Anyone
The question worth asking any buy-side advisor is what they were accountable for after the deal closed. Diligence is cheap to produce and expensive to get wrong, and the people who feel the difference are rarely the people who wrote the report.
We work a small number of mandates at a time, on the buy side only, and we say no when the price is already set.
