Ask most small and mid-sized agency owners how they got their last three clients and the answer is usually some version of the same story. A referral from a past client. Someone who used to work for them moved to a new company. A conference conversation that turned into a coffee that turned into a brief. That is not a weakness. Second Wind's annual survey backs this up directly: 74 percent of agencies report referrals working very often as a new business source, more than any other channel. There is no reason to walk away from what is working.
The risk is not that referrals stopped working. The risk is treating them as the whole strategy rather than one important piece of it. The same survey data shows other channels do produce results, just less consistently. Roughly three in four agencies find their website and social content effective at least sometimes. Around six in ten say the same about email, cold calling, and SEO. That pattern is telling. These channels are not failing. They are simply less reliable than referrals, which is exactly why they deserve more deliberate investment rather than occasional effort, the same way referrals already function as a dependable source.
A referral is something you receive. It depends on timing, on someone else thinking of you at the right moment, on a relationship that may or may not still be active when a prospect needs an agency. That is a real asset, but it is not a system, and an agency with nothing else running in the background is more exposed than it needs to be.
Some agencies are also seeing earlier and more formal vendor evaluation from larger clients, procurement involvement, RFP processes, more pressure to justify every vendor relationship to finance. That is real for agencies working with bigger accounts, but it is not universal. Many SW agencies work with smaller, founder-led, or regionally rooted clients where relationships still move faster than process. The strategy below matters either way, not because referrals are failing, but because no single source of new business should be the only one keeping the lights on.
Narrow the Lane
The agencies winning new business most consistently right now have stopped treating it as something that happens to them and started treating it as a system they run alongside their referral network, not instead of it. That starts with narrowing focus, not widening it. An agency that can credibly help any brand with marketing needs is invisible, because that description fits hundreds of agencies and gives a prospect no reason to call one over another. An agency known for one thing, a category, a problem, a methodology, gives prospects a reason to seek them out by name.
This is a harder short-term decision than staying broad, because it means turning away work outside the lane. It is also the only way to be the obvious call instead of one of many similar names a prospect is comparing.
Make Content Work Harder
Content marketing is not new to agency new business. What has changed is how much weight it now carries, and the survey data reflects that shift already underway. Social content and website content are already working for roughly three out of four agencies at least some of the time. The opportunity is making them work more often, not discovering them for the first time. A marketing leader trying to solve a real problem searches for it, reads what comes up, and forms an opinion about who understands the issue before any pitch meeting happens. If an agency's point of view is not visible at that moment, it is not in the conversation, regardless of how good the portfolio looks.
A clear point of view on a specific problem is what makes content worth writing and worth reading. Generic marketing advice indistinguishable from a thousand other agency blogs earns no credit. A sharp, specific argument about a problem the agency's target clients actually have starts showing up in the right conversations and earns inbound interest that supplements referral volume rather than replacing it.
Make Outbound Smarter, Not Louder
Mass outreach, the same templated email sent to hundreds of marketing directors, has gotten worse as AI tools make it easy for everyone to send more of it. The volume increase devalues every individual message, and prospects have gotten faster at spotting and ignoring it. That decline in effectiveness likely shows up in the survey's more modest numbers for email and cold calling: still useful, but inconsistent compared to referrals.
What works is outreach specific to the recipient, built on real research, sent by someone with a credible reason to reach out. This is more labor intensive and reaches fewer people, but the response rates are dramatically higher. The agencies thinking ahead use AI tools to do the research faster and then write the message themselves so it sounds like a person who did the homework rather than a tool generating variations.
Build a Pipeline That Does Not Depend on One Person
Many small and mid-sized agencies have a new business problem hiding behind an owner problem. The owner is the rainmaker, the face at every pitch, the person whose relationships built the client list. The moment that person is occupied with a difficult account, new business activity drops to zero.
The agencies building real resilience document what the owner actually does in the new business process and distribute pieces of it. Someone else can own the research behind outbound messages. Someone else can write under the agency's byline once the point of view is established. Someone else can run the first qualifying conversation before the owner ever joins a call. None of this replaces the owner's relationships or instincts, but it means new business does not grind to a halt every time the owner is pulled into client work.
Diversify Before Consolidation Forces You To
An agency overly dependent on one or two big accounts is more exposed than it used to be. Losing a major client used to mean a bad quarter. It can now mean losing a third of revenue overnight. The agencies thinking about new business correctly are not just trying to grow. They are making sure no single client relationship, and no single source of new clients, can sink the business if it ends.
The Pipeline Is the Business
New business is downstream of positioning. An agency that has not decided what it is actually known for cannot write content that lands, cannot make outbound sound specific instead of generic, and cannot give a referral source a clear enough picture to send the right client their way.
Referrals will likely keep doing the heavy lifting for most independent agencies, and the survey data confirms why: nothing else comes close to matching their reliability. That is worth protecting and nurturing deliberately rather than taking for granted. The agencies that grow steadily over the next five years will be the ones that kept their referral relationships strong while building a second and third source of new business alongside them, narrow enough to be memorable, visible enough to be found, and resilient enough to survive without depending on any single person, client, or source to keep it running.
