Most Amazon agency founders tell the same story when I ask how they got their first ten clients: referrals. A brand manager moves to a new company and brings the agency with them. An investor in one portfolio company recommends the agency to another. A PPC manager at a brand becomes the VP of Marketing and signs their first vendor contract.
This is a great way to build your first ten clients. It’s a terrible strategy for getting to twenty.
The Referral Ceiling
Referral-driven growth has a structural problem: it’s entirely dependent on timing and relationships outside your control. You can’t predict when a past client will recommend you. You can’t manufacture the moment when someone has a warm connection who needs what you offer.
More practically: referrals naturally dry up over time. Early clients age out. Relationships grow stale. The Amazon ecosystem shifts, and your original network doesn’t overlap with the brands that are growing fastest in 2026.
The agencies that hit $1M ARR mostly got there on the back of referrals, personal brand, and a few anchor clients who came in through luck or timing. To build toward $3M, $5M, or beyond, you need pipeline that doesn’t depend on any of those things.
You need a system.
Why Cold Calling Doesn’t Work for Amazon Agencies
The natural response when referrals slow down is to go outbound. Pick up the phone. Buy a list. Hire someone to dial.
This works reasonably well for generic B2B services targeting mid-market companies. It rarely works well for Amazon agencies, for two reasons.
First, Amazon brands are hard to reach by phone. The decision-makers — brand managers, heads of e-commerce, founders — spend their days on Amazon Seller Central, in Slack, responding to emails. They’re not sitting at desks waiting for sales calls. Cold calls to Amazon brand operators routinely go to voicemail or get bounced to receptionists at corporate offices that haven’t managed the day-to-day of their Amazon channel in years.
Second, phone calls don’t allow you to lead with data. The strongest pitch for an Amazon agency service is specific and grounded in the brand’s actual situation on Amazon: their category position, where their reviews stand, what their competitor’s ad spend looks like, what a reasonable benchmark for their ROAS should be. You can’t deliver that in a cold call. You can in a cold email — if it’s thoughtful and precise.
The agencies that have found cold outreach to work are doing it primarily through email and LinkedIn, with personalization grounded in actual marketplace data. That’s a very different motion than cold calling.
The SDR Trap
The next move most founders consider is hiring a dedicated sales development rep. This makes intuitive sense: you’re busy delivering for clients, someone else should be filling the top of the funnel for you.
Here’s the problem. A competent SDR in the B2B space costs $60,000 to $100,000 per year in base salary alone. Total comp with benefits and quota bonuses is typically $90,000 to $130,000. And that’s before you factor in the ramp time — 3 to 6 months where they’re learning the Amazon ecosystem, figuring out your ICP, and generating exactly zero qualified opportunities.
Even after they’re fully ramped, a traditional SDR approaches outreach as a volume game. They’re not analyzing Amazon data to identify the right brands at the right moment. They’re following a script and a sequence. Amazon agency services aren’t transactional enough for that approach to convert reliably.
You’ll spend six months and a substantial chunk of cash before you know whether it’s working. Most agencies that have tried this tell me they got one or two meetings that went nowhere before quietly letting the role go.

What a Systematic Pipeline Actually Looks Like
The agencies that have cracked outbound aren’t doing something exotic. They’ve built a process with three properties that referrals and generic SDRs lack:
It’s data-driven. The outreach starts from specific signals — brands in the right revenue range, in categories where the agency has demonstrated results, with evidence of Amazon investment. You’re not contacting every brand in a category. You’re identifying the subset most likely to convert, based on what you actually know about them.
It’s multi-channel and sequenced. The best outreach combines email, LinkedIn, and occasionally retargeting across a sequence long enough to register without being pushy. No single touchpoint is a pitch. The sequence earns the conversation.
It’s automated for volume, personalized for quality. The parts that don’t require judgment — finding brands, pulling contact data, executing follow-up sequences — run without manual work. The parts that require judgment — crafting the initial message, responding to early engagement — stay human.
This approach doesn’t require a full-time SDR. It requires the right data infrastructure and a clear ICP. Once you have both, you can run outbound at meaningful volume with a fraction of the cost.
The Shift from Reactive to Proactive Growth
The fundamental change isn’t tactical — it’s a shift in posture. Referral-dependent agencies are reactive. They respond to inbound signals: the former client who reaches out, the investor introduction, the conference conversation that turns into a proposal. These things happen on other people’s timelines.
Agencies with systematic pipelines are proactive. They decide which brands they want to win. They build the data to identify those brands. They design the outreach to start the conversation. They control the inputs, which gives them far more influence over the outputs.
This doesn’t mean the relationship-based instincts stop mattering. It means you’re applying those instincts at scale, to brands you’ve already determined are a fit, rather than waiting to see who shows up.
If you’re at a point in your agency’s growth where you feel like you’ve exhausted the referral channel and aren’t sure what comes next, the problem usually isn’t effort. It’s infrastructure. You need a systematic approach to finding the right brands, starting the right conversations, and converting them into clients.
