We've sat on the buyer's side of the table hundreds of times, across every kind of agency deal. Every time, the price comes down to one question: what's the probability the revenue continues once you're gone.
If you're the reason the agency works, it stops working properly the day you leave. Buyers price the agency that will exist six months after completion, not the one you're running today. Understanding exactly how they do that maths is the difference between a 3x deal and a 5x deal on identical financials.
What 3-5x actually means
Standard agency multiples run between three and five times net income, averaging around 3.7-3.9x. That range is a confidence interval. Most founders spend the process trying to push EBITDA up in the trailing twelve months, which does move the price, but linearly.
A point of multiple moves it faster, and multiple is earned almost entirely by evidence gathered outside the P&L: who owns each client relationship, how the team is structured, how clean the operations are.
If you're eight months from a process and choosing where to spend your energy, fixing relationship concentration usually buys more multiple than fixing margin.
The five things buyers actually check, and the thresholds they use
Senior team retention. Buyers want named people mapped against named clients, not an org chart. A common rule of thumb: if any one person's departure would put more than 15-20% of revenue at risk, that's flagged as a concentration issue, not just a nice-to-have to fix. The fix isn't just a retention bonus. It's evidence the person has a growing role and equity or bonus structure that ties their upside to the next three years, not the last three.
Client concentration and relationship depth. Two numbers matter here: what percentage of revenue sits with your top three clients, and how many of your senior people that revenue touches. Buyers get nervous above roughly 40% concentration in the top three, and they get far more nervous if all three run through one person. The same 40% split across five relationship owners reads completely differently to a model than it does on a slide.
Founder dependency. This gets tested directly, not inferred. We've seen buyers request calls with account directors with no founder present, request to see who actually signs off creative or strategy day to day, and in a few cases turn up unannounced during diligence to see if the agency runs the same on a day the founder isn't in. What they're building is an estimate of what percentage of EBITDA is genuinely founder-dependent versus institutionalised. That percentage, more than almost anything else, drives where you land in the 3-5x range.
Operational cleanliness. Documented processes, utilisation rates that hold up under scrutiny, margin discipline, no surprises in working capital. This is the least interesting item on the list and the one that kills the most deals, because problems that surface in week four of diligence read as things that were hidden, whether or not that's true. A clean data room shortens diligence and reduces the number of things a buyer can point to when negotiating the multiple back down.
Founder behaviour post-deal. Buyers price in an assumption about how much you'll interfere. A founder who's built and named a successor, who can articulate what they'll actually do on Monday morning post-completion that isn't "the same job with a different owner," reads as lower risk than one who can't answer that question cleanly.
How the retention liability calculation actually works
Before a serious buyer lands on a number, they run a retention liability model, not just a gut feeling. Average senior team turnover in the first year after an agency acquisition sits around 47%. That number is baked into most buyers' models as a base case, not a worst case.
The mechanics: take your forecast revenue, discount the portion tied to people whose departure probability is elevated, discount again for the clients those specific people could plausibly take with them based on relationship strength, and price the deal off that adjusted number. This is typically where earnout structures come from. A buyer who can't get comfortable with the base valuation on day one will often propose the same headline multiple but push 30-50% of it into a two or three year earnout tied to revenue retention. That's not a negotiating tactic, it's the buyer converting an uncertain risk into a contractual one they don't have to price today.
This is why two agencies with identical P&Ls get different offers. Spread the same revenue across five people who each own direct relationships, and losing any one of them puts a manageable slice at risk. Run it all through the founder, and losing the founder puts most of it at risk simultaneously. The second agency doesn't just get a lower multiple, it gets a worse earnout structure, because the buyer needs more time to prove retention before they'll pay in full.
You can't fix trailing financials six months out. You can fix who holds your client relationships eighteen months out, and it moves both the headline multiple and the shape of the earnout.
Why leaks during diligence cost real money
We've watched the same sequence often enough to predict it.
Diligence opens fine. Two or three weeks in, small things surface: unusual LinkedIn activity from a senior person, a client asking about notice periods out of nowhere, someone mentioning to a contact at another agency that something's happening. None of these show up in a single document. They show up as a pattern the buyer's advisors notice across conversations.
Once flagged, the offer that was tracking at 4.5x typically comes back at 4x with a heavier earnout, usually labelled "integration risk." The adjustment almost always traces back to those informal signals rather than anything in the actual diligence findings. The buyer is repricing based on inferred retention risk, not measured performance risk.
By the time you're told the multiple has moved, the trigger is usually six weeks old, and it's a sequencing failure: someone found out before you controlled how they found out. The fix is entirely within a founder's control and costs nothing except planning.
Sequencing the internal story
Decide the order people learn things before the process starts. As a working structure: senior team who need to be in the data room learn first and get a real stake in the outcome; the wider team learns at a defined point tied to specific deal milestones, not whenever gossip fills the gap; clients learn last, from the person who owns the relationship, with a message about what gets better for them, not what changes for you.
The content of the story matters as much as the order. For the team, it needs to be specific: named new capabilities, named new client opportunities, a real path to more responsibility or equity, not generic reassurance that "nothing will change." Vague reassurance reads as evasive and generates more anxiety than silence would.
For clients, the message is the same relationship with more resource behind it. This only works if it's true, which is why the relationship-mapping work has to happen before the story gets told, not after.
The test that matters: the story the buyer hears at LOI, the story the team hears at the all-hands, and the story clients hear at their first post-deal meeting need to line up exactly. Buyers cross-reference these during diligence, formally or informally, and a mismatch is one of the fastest ways to convert a clean process into a repriced one.
What we do on this at Succeed
We map the client base account by account before a process starts: revenue by client, relationship owner by client, and what percentage of total revenue sits with people other than the founder. That number, more than the P&L, is what we use to predict where an agency will land in the 3-5x range.
We do the same exercise with the senior team, and we push founders to fix concentration problems well before a process starts, because the fix takes months and the diligence window doesn't give you that time.
Then we build the communication sequence and timeline alongside the deal timeline, not after it, so the LOI story, the all-hands story, and the client story are locked before anyone outside the founder and the deal team knows a process is live.
If you want an honest read on where your agency sits against these thresholds before you're in a live process, book a confidential evaluation with us.
