Get in Touch
Let’s have an honest conversation.
Whether you’re ready to sell, planning years ahead, or looking to acquire — reach out. Everything we discuss is strictly confidential. No pressure, no obligation.

Every conversation is treated with strict confidentiality.
For Business Owners
You built something valuable. We help you realize that value.
Most founders only sell a business once. Buyers do it dozens of times. That experience gap is where value gets lost — in the negotiation, in diligence, in the terms you didn’t know to push back on. McNath Partners closes that gap before you ever sit across the table from a buyer.

What We Do For You
End-to-end advisory. Nothing left to chance.
01
Business Assessment
We evaluate your business the way a buyer will — before they do. Financials, customer concentration, key-person risk, recurring revenue quality, and any structural issues that could reduce your valuation or kill a deal in diligence. We find the gaps first so you can address them on your terms.
We build the Confidential Information Memorandum, financial model, and management presentation in the language PE firms and strategic acquirers understand. We frame your business to hit the metrics buyers underwrite and tell the story that justifies a premium multiple.
We identify strategic buyers, PE platforms, and family offices who will pay a premium for your business specifically — then run a structured process that creates real competition without shotgunning your deal to 200 parties. Confidentiality is maintained throughout.

Negotiation
We’ve sat on both sides of the table. We know what buyers are really asking for when they push on reps and warranties, earnouts, and working capital pegs. We negotiate price, structure, and every clause that affects your actual outcome — not just the headline number.

Diligence & Close
Deals die in diligence. We manage the full process — coordinating your counsel, your CPA, your management team, and the buyer’s side — keeping all parties aligned and maintaining momentum from signed LOI to wire transfer.

Questions We Answer First
What every seller needs to know.
Is my business ready to sell?
We assess your business against what buyers will scrutinize — EBITDA quality, customer concentration, key-person dependency, recurring revenue, and operational systems. We find the gaps before buyers use them as negotiating leverage against you.
What is my business actually worth?
EBITDA × multiple is just the starting point. The real valuation depends on revenue quality, customer stickiness, management depth, sector dynamics, and the specific buyers in your process. We model all of it.
Who should buy my business?
The highest bid isn’t always the best deal. Some buyers will run your business well; others will strip it down or leave your team in a difficult position. We know the difference and we guide you toward the right outcome, not just the highest number.
How do I maintain confidentiality?
We manage the process so your employees, customers, and competitors never know a sale is underway until you decide to disclose. NDAs, staged disclosure, and careful buyer sequencing protect your business throughout.
What does the process actually feel like?
Intense but manageable when you have the right advisor. We handle the buyer communications, the data room, the management presentations, and the negotiation. Your job is to run your business. Our job is to sell it.
Exit Readiness Planning
Not ready to sell today? Start preparing now.
The best exits are planned 1–3 years in advance. Business owners who work with us early close faster, at higher multiples, with fewer surprises in diligence. We identify the gaps buyers will find and help you close them before they cost you at the table.
Financial Clean-Up
Normalize your EBITDA, separate personal expenses, establish clean financial reporting, and build the 3-year track record buyers want to see.
Management Depth
Reduce key-person dependency by building a team that can operate without you. Buyers pay premiums for businesses that don’t walk out the door with the founder.
Revenue Quality
Shift your revenue mix toward recurring contracts, reduce customer concentration, and document what makes your business sticky. These are the metrics that drive multiple expansion.
Ready to have a confidential conversation?
No pressure. No obligation. Everything we discuss stays between us.
Deal flow worth your time. From people who understand the business, not just the model.
We source, vet, and present lower middle market acquisition targets to private equity firms and family offices. Our operator backgrounds open doors that traditional intermediaries can’t — and our diligence filters mean you only see opportunities that are worth your attention.
Why McNath Partners
We give you access before it goes to market.
Most PE deal flow is recycled — the same businesses hitting the same platforms at the same time. We build direct relationships with business owners years before they’re ready to transact.
01
Operator Credibility That Opens Doors
Our founders built, scaled, and exited lower middle market businesses. Business owners talk to us candidly because we’ve been in their position. That trust translates into access you won’t get through a traditional intermediary.
02
Pre-Vetted, Not Pre-Packaged
Every target we present has been assessed for financial quality, management depth, customer concentration, and transaction readiness. You get the honest picture, not the CIM version. We surface the issues early so you can decide fast.
03
Proprietary Flow in Core Sectors
We cultivate owner relationships in building services, specialty services, healthcare services, and adjacent sectors — industries where PE consolidation is active and quality operators are hard to find.
04
Thesis-Driven Origination
Tell us your acquisition criteria and we proactively source against it. We don’t send you everything. We send you what fits, because our reputation depends on not wasting your time.
05
Efficient Process Management
We manage the seller relationship, information flow, and timeline on your behalf. We reduce friction, maintain momentum, and keep sellers engaged so deals don’t die from slow process management.
06
No Conflicts
When we work with you on a buy-side engagement, that’s the only side we represent on that deal. Clear structure, clear alignment, clear incentives.
Our Approach
How we work with your firm.
From thesis intake to close support, we’re a true operating partner in your deal sourcing.
01
You Share Your Thesis
We start with a detailed conversation about your investment criteria — EBITDA range, sector focus, geography, platform vs. add-on, management requirements, deal structure preferences. The more specific you are, the better we target.
02
We Originate Against Your Criteria
We work our existing owner relationships and develop new ones in your target sectors. Direct conversations with business owners — not brokers, not databases — surfacing candidates that genuinely fit your profile.
03
We Assess and Filter
Before anything comes to you, we conduct a preliminary assessment of financial quality, customer base, management, and structural issues. You get the unfiltered version — risks and all — so you can decide without wasting resources on preliminary diligence.
04
We Manage the Introduction
When you have interest, we facilitate a warm introduction and manage the seller’s expectations. Because the owner already trusts us, the dynamic in that first conversation is completely different from a cold approach.
05
We Support Through Process
From LOI to close, we help keep the deal moving — managing the seller relationship, facilitating information requests, and troubleshooting the issues that arise in LMM transactions where owners are often first-time sellers.

Mac Weinles
Founder & Managing Partner
Mac’s path from accounting to operator to PE-backed founder to successful exit gives him a perspective few intermediaries can offer. He understands what PE looks for when underwriting an LMM business because he went through the process from the seller’s seat. He knows how owners think, what makes them trust a buyer, and what kills deals that should close.
Nathan came up through the trades before building a prominent commercial real estate portfolio in New York City. His background gives him credibility with the business owners we work with, and his track record as a dealmaker in one of the world’s most competitive markets gives him the transactional sophistication to navigate complex negotiations.
