How to Build a Proprietary MSP Deal Pipeline

Last updated: October 5, 2026
Written by Rhett Collver, Managing Partner, C4 Solutions

Picture a platform MSP with capital, a buy-and-build plan, and three broker relationships. Six months in, it has seen four listed deals. Each one arrived as a teaser that every buyer on the broker’s list also received, with a date for indications of interest and a seller who had already heard what a peer supposedly sold for. The platform lost two, overpaid for one, and walked away from the fourth.

Nobody did anything wrong. A brokered process is built to get the seller the best price. That’s the broker’s job. They’re good at it.

Proprietary MSP deal flow works from the other end. You pick the owners you’d want to buy, reach them before they’ve called anyone, and stay in touch until the timing works for them. It’s the discipline behind our MSP acquisition deal flow services and the buy side of our MSP M&A advisory practice. This guide lays out how to build the same kind of pipeline yourself, what to track, and where most buyers give up too early.

Rhett Collver leads that work at C4 Solutions. He built an MSP and ISP past $5 million in revenue and exited, then spent years in investment banking structuring acquisitions, so he knows what an owner weighs before taking a buyer’s call and what a buyer has to prove once they do.

What Proprietary MSP Deal Flow Actually Means

Proprietary deal flow is any acquisition opportunity you source directly from the owner instead of receiving it through a marketed sale process. In MSP acquisition sourcing, it usually means an owner who hasn’t hired a broker, hasn’t sent out a teaser, and is talking to you first, sometimes only you, about a possible deal.

The word gets stretched. A deal a banker quietly shows to five preferred buyers isn’t proprietary. Neither is a listing you happened to spot before your competitors did. The test is simple. Did the owner start the conversation with you, or with the market?

It also rarely means exclusive forever. Once an owner gets serious, plenty of them bring in an advisor or test the market. Your edge is position. You were first, you understand the business, and the owner already knows how you operate.

Why the Owners Are Out There, and Why You Can’t See Them

The Census Bureau’s Annual Business Survey found that over half of U.S. business owners were age 55 and over. Plenty of MSP founders who opened shops in the late 1990s and 2000s are in that group now. Succession is coming for a lot of them, whether they’ve planned for it or not.

Most haven’t. C4’s M&A team sees the same pattern again and again. The average owner decides to sell about 18 months before they need to, and by then the books are messy and the team still leans on the founder for everything.

The reasons an MSP owner starts thinking about it are rarely dramatic.

• The security burden keeps growing. Cyber insurance questionnaires, client compliance demands, and around-the-clock monitoring expectations land on a founder who started out fixing printers.
• A partner wants out. Now somebody has to buy them out, and the remaining owner starts doing math.
• A senior engineer leaves, and the owner realizes how much of the business walked out the door with them.
• Tool and licensing costs climb every year while client pricing lags behind.
• A platform backed by private equity opens down the street and starts hiring their people.
• Twenty years of being on call. That one’s enough by itself.

None of that shows up on a business-for-sale marketplace. It shows up in a conversation, and only if you’re already the buyer that owner is talking to.

Step One: Write the Acquisition Thesis First

Every buy-side deal pipeline starts on paper. Not the list. The thesis.

A thesis is a short, specific description of the MSP you want to own and why it fits the one you already run. Write it down before you research a single company, because it decides everything that follows, from who makes the list to what your first letter says.

• Geography, measured in drive time if your engineers still do on-site work.
• A revenue band, plus how much of that revenue must come from recurring managed services contracts.
• One or two verticals where your team already knows the compliance and the software.
• Stack fit. An MSP on ConnectWise or Autotask is a different integration project than one on HaloPSA or NinjaOne, and your engineers will tell you which one they’d rather inherit.
• A ceiling on client concentration, so one departing client can’t sink the deal.
• The owner situation you can work with, whether that’s someone ready to step back in a year or a founder who wants to stay and run the division.

That’s an example. Not a template. But notice what it does. Specific criteria shrink the list to companies you can research properly, and they hand you a straight answer to the first question every owner asks, which is why you.

Step Two: Build the Target Universe

With the thesis in hand, the list almost builds itself. Almost.

Start with LinkedIn company search and Sales Navigator, filtered by headcount, location, and industry, and expect to spend real time cleaning what comes back, because LinkedIn headcounts are often stale and plenty of owners barely use the platform. Add the partner locators run by the RMM, PSA, and security vendors MSPs resell, local business journals, and the member directories of chambers and industry associations. Peer groups like HTG and communities like The ASCII Group and CompTIA are where owners show up in person, so they matter more for relationships than for lists. Data tools like Apollo fill in contact details once you know who you want.

It’s the same discipline as building a Dream 100 list, pointed at owners instead of clients. A tight regional thesis may leave you a surprisingly short list. Good. Short lists get researched properly.

Then tier it. Tier one fits the thesis and shows signals that the owner might listen, like a founder who has run the business for 15 years or more, no visible second-in-command, a recent leadership departure, or job posts for roles the owner used to cover personally. Tier two fits the thesis but shows no signals yet, and tier three is a partial fit you keep an eye on in case the owner’s situation or your own criteria change.

This is the slowest part of the whole process, and it’s where C4’s deal flow team gives buyers a head start. We maintain our own database of MSPs, IT service providers, and VARs across North America and filter it against each buyer’s criteria, which skips the first few months of list building.

Step Three: Give Owners a Reason to Pick You

Most acquirers open with some version of “we’d love to learn more about your business.” Owners who have been around a while have read that line many times. It says nothing about what happens to their people.

What an owner actually weighs is personal, and price is only one piece of it.

• Their team. The engineer who’s been there 12 years. The office manager who knows every client’s birthday.
• Their clients, who trusted them with everything and will call them first if service slips after the sale.
• Their name on the door. Some owners care deeply about the brand surviving. Some couldn’t care less. Ask.
• How much of the price is cash at close versus an earnout or rolled equity, and how long they’d be expected to stay.
• And yes, the number.

Your positioning should answer those plainly. An operator buyer can talk credibly about continuity for staff and clients. A financial buyer should be upfront about the platform strategy and what integration will look like. If you’re backed by private equity, owners will research what that means, and our breakdown of PE-backed MSP acquisitions covers what they’re likely to read.

One more thing. The owner will look you up on LinkedIn before they reply. Make sure your profile explains why you acquire, what you’ve bought before, and what happened to those teams afterward.

Step Four: Run Outreach That Outlasts Your Patience

Reaching an owner who isn’t looking to sell takes more than one email. The channels are familiar. A personal letter, LinkedIn, email, and the phone, each one reinforcing the others, so a name the owner saw on an envelope is a name they recognize when it shows up in their inbox two weeks later.

Don’t underestimate the letter. When every other buyer is emailing, a short signed letter on real paper is the touch an owner actually remembers.

The first message matters most. Compare these two.

Email to owners is still commercial email. The FTC’s CAN-SPAM compliance guide says the law makes no exception for business-to-business email, so every message needs an honest subject line, a real postal address, and an opt-out you honor within 10 business days.

Then comes the part that separates buyers who build a pipeline from buyers who send a campaign. Keep going. Run an initial sequence over a few weeks, and then keep a light, steady touch every quarter for every owner who didn’t say no. A short note when you close a deal elsewhere. A note of congratulations when their company hits an anniversary. A question about how they’re handling some new compliance requirement their clients are asking about.

Patience isn’t optional here. Stanford GSB’s research on search funds, investment vehicles for entrepreneurs who spend their first couple of years doing nothing but hunting for one company to buy, found that acquiring a company typically takes around 20 months, and only about half of the search funds launched between 2021 and 2024 had acquired a company. Full-time buyers. Twenty months.

Step Five: Qualify Early, Then Move to NDA

The first call isn’t diligence. It’s two operators figuring out whether a deal could make sense for both of them. Learn the owner’s goals, their timeline, and what they’d want for their team, and let them ask you just as many questions, because they’re deciding whether they could ever hand their business to you. Get a rough sense of size, the recurring share of revenue, how concentrated the client base is, and who the key people are.

If it still fits, move to a mutual NDA and a first look at the financials, typically the P&L, a breakdown of recurring revenue, and client concentration. If that holds up, an indication of interest or a letter of intent comes next. Our exit-ready MSP framework is written for sellers, but it doubles as a checklist of what a buyer should look for once the numbers show up.

When it doesn’t fit, say so quickly and kindly. Owners talk to each other in peer groups. Word travels. A buyer who strings people along for months earns a reputation that makes the next hundred letters harder to answer.

Track It Like a Sales Pipeline

A proprietary deal pipeline behaves like any long-cycle sales pipeline, and it needs the same discipline. Every owner sits in exactly one stage, and every stage has a number worth watching.

The most valuable group is the one most buyers neglect, the owners who said “not now.” They told you something useful. Believe them. Write down their stated timing, whether it’s after a big contract renewal, after a partner retires, or after a child finishes college, and come back exactly then. Most buyers won’t. The ones who do are often the only buyer in the room when that owner finally decides.

Set expectations inside your own firm, too. On C4’s deal flow engagements, early responses usually start within the first few weeks, and qualified seller conversations generally begin within about 30 days, depending on the criteria, deal size, and market. Closing takes far longer. A pipeline that looks slow in month four is usually just a pipeline in month four.

Where Brokers Still Fit

Brokers still matter. They serve sellers, which is exactly why their deals come as competitive processes, but a good broker still brings real opportunities you’d never find on your own. Most serious acquirers run both, using the broker channel for deals already in motion and a proprietary pipeline to fill the long gaps between them. If you want to know who’s worth a relationship, our list of the MSP business brokers and sell-side advisors worth knowing is a good place to start.

Build It In-House or Hand It Off

Building it in-house takes a corporate development hire or a principal who protects real hours every week, a CRM, a data source, a budget for letters, and 12 to 24 months of patience before you judge the results. Plenty of platforms manage it.

The alternative is handing the sourcing to a team that already runs it. C4’s deal flow team builds the target list against your criteria, runs the outreach across channels, manages the early conversations, and hands you owners who are genuinely open to talking. You show up for the deal conversation.

Either way, the parts don’t change. A thesis, a list, a reason to pick you, patient outreach, and a pipeline you actually track. If you want help with any of it, talk with our M&A team about your acquisition criteria and we’ll show you what a proprietary pipeline could look like for your market.
