How to find clients for your agency when you don't know who to pitch next

Every agency hits this wall eventually: the referral pipeline that got you your first clients slows down, and you realize you don't actually have a list of who to pitch next, just a vague sense of "small businesses that need marketing help." That vagueness is the actual problem, more than any tool or technique. A list of 40 real companies with a named decision maker at each is worth more than a thousand generic "small businesses in my area."

This costs you real money every week it stays unsolved: no new pitches means no new pipeline, and pipeline built today doesn't close for 30 to 90 days, so a slow month now is a slow quarter later.

Start here: the free and cheap options

Before paying for anything, work through these in order:

• Referrals and past clients. Free, and the warmest leads you'll ever get, since someone is vouching for you. The limit is volume: most agencies exhaust their obvious referral asks within the first few weeks of actually asking. Spotting a past client who moved to a new company is one easy way to reopen those.
• Manual search on LinkedIn Sales Navigator. Good fit data (you can filter by title, company size and industry with real precision), but it's slow and entirely hand work. There's no built-in way to export a clean list with verified emails; you're copying names and guessing at contact details, or paying separately for an email finder on top.
• Your own network, one layer out. Ask the people you already know who they know. This sits between referrals and cold prospecting and costs nothing but time.

If you genuinely have fewer than 20 target firms in mind, a hand-built list from these sources is cheaper and faster than any paid tool. The work of setting up a database search, filters and export isn't worth it for a list that small; you'll finish the list by hand before the trial period on a paid tool even gets interesting. Amplemarket, a paid B2B database you search by industry, size and title to pull a list of companies with verified contact details attached, is the option at the top end of the table below.

Option	Cost	Speed	Contact detail included
Referrals and past clients	Free	Depends on your network	Yes, you already have it
Manual search on LinkedIn Sales Navigator	Sales Navigator subscription only	Slow, all hand work	No, names only, you source emails separately
Apollo.io	Cheaper database with built-in sequences	Fast, but data quality varies by niche	Yes, variable accuracy
Amplemarket	From $600/mo (Startup, annual)	Fast, filtered export	Yes, verified emails and phone numbers

The honest read on that table: the middle two rows are where most small agencies actually sit for a while, Sales Navigator for the filtering, something cheaper like Apollo.io for emails, before ever paying $600 a month for a bundled tool. Amplemarket is worth the jump once you'd rather pay for the bundle than manage two subscriptions and a manual export step between them.

Where a tool like Amplemarket actually helps

Amplemarket's B2B database and search tool gives you filtered access to a database the company states covers 200 million-plus business contacts, refreshed by more than 70 million updates a week. In practice, that means you can filter by industry, company size, job title and location, and get back a list with names, verified emails and (on most plans) phone numbers, rather than just company names you'd have to research one by one.

The real value isn't the search itself, Sales Navigator gives you similarly precise filters, it's that Amplemarket returns contact details ready to use, instead of a name you then have to go find an email address for separately. That's the actual time saved: not finding the right companies, but turning a list of companies into a list of people you can actually email.

Pricing: the Startup plan is published at $600 a month on annual billing terms, for 2 users and access up to 27,000 contacts. Growth and Elite plans scale up (140,000 and 400,000 contacts respectively) but aren't published with a flat price; Amplemarket quotes those on a call, so budget on getting an actual number before assuming a figure. Starting a trial is the fastest way to get that real quote and see the database coverage for your specific niche before committing.

Step by step: building your list without wasting the trial

1. Write down the exact job you're trying to do. "Find marketing-decision-makers at 20-to-200-employee retail companies in my region" is a filterable job. "Find companies that need marketing help" isn't, it's too vague to filter on, and you'll burn your trial period refining the search instead of using it.
2. Count how often this job recurs. If you're building this list once and working it for months, the math is different than if you need a fresh list every week. A one-time list might be cheaper to build by hand; a recurring need is where a database tool starts paying for itself.
3. Try the free or hand-built option for two weeks first. This isn't just about saving money, it tells you whether referrals and manual search already cover your actual pipeline need, in which case you don't need to pay for anything.
4. If the free route genuinely falls short, trial the paid tool against your exact filter criteria before paying for a full year, and check the actual contact count the filters return against your market, not just the headline 200M+ figure, since that number covers every industry and country, not yours specifically.

A worked example: is it actually worth $600 a month?

Say your agency closes one new client a quarter from cold outreach, at an average contract value of $3,000 a month. That's $9,000 in revenue from a quarter's worth of prospecting. If building and working a list by hand takes you, realistically, 10 hours a week across the quarter (finding companies, hunting for contact details, verifying emails that bounce), that's 130 hours of your own time for one closed client. At any reasonable hourly value for your own time, the hand-built route is expensive, it's just expensive in hours rather than dollars, which is easy to undercount.

Now run the same math with a filtered database search. If Amplemarket's $600-a-month Startup plan cuts that list-building time from 10 hours a week to 2, you've recovered roughly 104 hours across the quarter, worth far more than the $1,800 you'd pay across those three months, assuming your time is worth more than about $17 an hour. The database tool doesn't make your outreach more effective; it makes the unglamorous part, finding who to contact, fast enough that you spend your actual hours on the outreach itself instead.

Where this math flips: if you're not actually going to use the extra time productively, say you free up 8 hours a week but don't have a follow-up process to fill them with outreach, you've paid $600 a month for time you didn't use. The tool only pays for itself if the bottleneck really is finding contacts, not what happens after you have them.

A second scenario: prospecting into one specific vertical

The math changes again if you're not prospecting broadly but targeting one specific vertical, say property management companies or regional distributors, where you already know roughly how many target firms exist in your market. In that case, before you ever open a database tool, it's worth a rough headcount: search Google Maps or an industry directory for your category plus your region and get an approximate count. If that number comes back under 50, you've likely found most of your actual addressable market already, by hand, for free, and a $600-a-month database subscription is solving a problem that doesn't exist for you. If it comes back in the hundreds, that's exactly the situation a filtered database search earns its cost, since manually researching contact details for 300 companies one by one is a multi-week project that a filtered export does in an afternoon.

What I'd actually tell a small agency owner

If you're reading this because referrals have dried up and you genuinely don't know who to call next, my honest read is that the database itself usually isn't your bottleneck, the follow-up is. A list of 200 names with no plan for how you'll reach out, in what order, with what message, sits unused just as easily as no list at all. Before you pay $600 a month for Startup, make sure you actually have the capacity to work a list that size; if you're a one- or two-person shop, a smaller, better-worked list of 50 real prospects usually outperforms a larger one you never fully contact. Once the list exists, deciding which prospects to call today keeps the effort focused.

Where this is genuinely worth it: once you're past the "who do I even call" stage and into "I know my ideal client profile, I just need more of them," a filtered database search turns a vague ideal-client description into an actual list in an afternoon, which is the part that used to take weeks of manual research.

When to skip this, and when it's worth a custom build

Skip a paid database tool if you have fewer than 20 target firms in mind right now, your referral pipeline is still producing work, or you don't yet have a specific, filterable description of who you're trying to reach. In all three cases, the $600-a-month Startup plan is solving a problem you don't have yet.

Where it's worth going further than the tool itself: if you're running this same prospecting process for multiple niches or multiple client accounts (common for agencies that do lead generation as a service for their own clients, not just themselves), doing each search by hand in the dashboard gets repetitive fast. That's a case for a small custom build on Amplemarket's API that runs your saved filter criteria on a schedule and drops fresh contacts straight into whatever CRM or spreadsheet you already work from. I build exactly that kind of connective tooling, and if you've already got a half-built version of this that never got finished, picking it up is usually faster than starting over.

One more thing worth deciding up front, before you pay for anything: who on your team actually owns the follow-up. A fresh list of 200 contacts that sits in a spreadsheet nobody works is the single most common way this goes wrong. Decide that first, then pick the tool that fits the volume you can actually follow up on, not the other way around.
