Lead generation for agencies: reach the client before the review

Referrals are drying up on the client's side

Ask an agency owner where new clients come from and most will say referrals. RSW/US found 75% of marketing and professional-services firms call referrals their best source (September 2025). Now look at it from the client's side. In RSW/US's January 2026 outlook, the share of marketers who found new agencies through networking fell from 73% in 2022 to 58% in 2025. Through friends or co-workers it fell from 60% to 35%.

Outbound is the obvious replacement, and the results are uneven. In SparkToro and Paddy Moogan's State of Digital Agencies 2025, 59% of agencies had tried it. Only 9% called it very effective, and a third said it didn't work at all. The same survey found 73% of agencies rate LinkedIn as their best new-business channel, and 70% have no full-time salesperson.

My read: the 9% aren't sending more messages than everyone else. They're sending them to fewer people at better moments. Nobody has published data that proves it, so take it as an opinion. The rest of this page is about those moments.

A new marketing leader, about three months in

This is the best-documented trigger, and the one most agencies act on too early. Winmo tracked more than 2,400 CMOs over eight years. A new agency of record was typically named 6 to 18 months after the CMO started, and the best time to get in touch was 3 to 12 months in. New leaders spend their first hundred days or so listening and auditing before they commit to a plan, so a pitch in week two arrives before there's anything to pitch into.

1. Weeks 1 to 4: a short note about the new role and a question about what they're tackling first. No deck, no case studies.
2. Months 2 to 4: one specific observation about their marketing that could feed the plan they're writing.
3. Months 3 to 12: the proposal, once there's a plan and budget is moving.
4. Around month 30: Winmo found CMOs often leave between their 30th and 45th month, and the cycle starts again with whoever replaces them. Keep watching the company, not only the person.

Two caveats. Winmo sells sales-intelligence data, last updated these figures in 2022, and studied big-brand CMOs. A Head of Marketing at a 40-person company probably moves faster, with a smaller budget and fewer sign-offs, though I haven't found data on it. And if you've worked with this person before, at their last company, skip most of this: a new leader bringing in an agency they already trust is the strongest version of the signal there is.

Why clients say they leave

Agencies tend to blame the new boss when they lose an account. In the SoDA Report (2016, 629 respondents), 56% of agencies said a change in client management was why they were fired. Clients ranked leadership change seventh, at 18%. Their top reason was price or value, at 37%.

The data is old, but the gap is the useful part. If clients mostly leave over value and delivery, then visible signs that the work has stalled are worth watching: a blog or LinkedIn page that hasn't posted in two months, ads in the Meta Ad Library still running the creative from last spring (or no ads at all), an agency credit that has quietly left the site footer. Use what you notice to ask a question. Nobody wants a stranger telling them their current agency is slipping.

Job ads can mean they're replacing you

A company hiring marketers looks like a company spending on marketing. Sometimes it is. Sometimes it's bringing your kind of work in-house. The ANA's 2023 survey found 82% of its members run an in-house agency (42% did in 2008), and 65% had moved some work from outside agencies to it in the previous three years. Social, search and digital creative moved most often.

So read the role before you count it as a signal. A Head of Marketing or VP Marketing opening means a new leader is coming, which puts you at the start of the timeline above. A marketing manager ad that lists “managing agencies” in the duties tells you agency budget exists. Three paid-social specialist ads at once usually mean a team is being built to replace an agency. And a senior ad that keeps getting reposted after six or eight weeks means they can't find the person, which is when interim help is easiest to sell.

Most companies end up somewhere in between. In a November 2023 survey of Australian marketers by the In-House Agency Council and Kantar, 78% used an in-house team and outside agencies together.

Funding: write to the hire, not the founder

Every agency in a startup's niche emails the founder the week a round is announced. The usual advice after a raise is to hire a marketing leader first and set the budget after, so the person who will actually choose an agency often joins a month or three later. Watching for that hire, or for the Head of Growth ad, gets you to the decision-maker while the founder's inbox is still full of congratulations. I couldn't find solid data on how long the gap runs, so treat one to three months as a rough guide.

Signals that look better than they are

• A like on a competitor agency's post. People like posts from the agency they already use, or from friends who work there. Next to a new role or a job ad it means more; alone it says little.
• A public RFP or an "accounts in review" story. By then you're one of many, and the incumbent or a consultant's shortlist has the edge. The ANA and 4As put the average cost of a pitch for big advertisers at US$408,500.
• A funding announcement in the week it lands, for the reason above. Everyone else saw it too.
• A profile view. It's useful for timing and should never appear in the message. "Saw you viewed my profile" turns interest into surveillance.

Doing it by hand

1. Keep a sheet of every marketing contact at your past and current clients. Once a month, check who has changed jobs, and write to them two to four months into the new role.
2. Save LinkedIn Jobs searches for Head of Marketing, Marketing Director and VP Marketing in your niche and region, filtered to the past week. Note when each ad goes up, then watch for the hire.
3. When someone you'd like to work with starts a new role, put reminders in your calendar for week six and week twelve.
4. Post a teardown of something in your niche, then look at who in your target market engaged with it. It's a signal you made yourself, and it gives you an honest reason to write.
5. Look up a prospect's ads in the Meta Ad Library before you write. Two minutes there usually turns up something specific to ask about.

There's a longer version of this, for any business, in how to find leads showing buying signals, and a table of how long each LinkedIn signal stays useful.

What Bingle does, and what it doesn't

Bingle watches LinkedIn for the people side of all this: new leaders in the function you sell to during their first 90 days, job changes, companies hiring for roles you name, funding, comments on competitor agencies' posts and your own profile viewers. It ranks each person by how well they fit the clients you want and how fresh the signal is, then writes a first message for you to approve.

The writer follows the rules on this page. A new role gets a brief mention and a question about what that person is tackling first, never a bare congratulations. A profile view or a like on a competitor's post decides who gets a message and when, and is never mentioned in it. Every message waits for your OK unless you turn review off.

Two limits, honestly. Bingle weights a new leader most in their first few weeks and lets that fade over the following months. That suits starting the conversation and is early for a proposal, which is still your call, months later. And it doesn't check ad libraries or site footers. Those stay manual.
