Who it is for
For B2B tech companies from Series A onward with a sales team, whose prospect list building is done by hand from one data source, or bought from a vendor and never checked.
Someone builds each list by hand, and the outreach waits until it is done.
Lists pulled from the same few databases reach the same contacts your competitors reach.
Unverified addresses bounce, and every bounce makes the next email less likely to arrive.
What you get
We build the lists in Clay, write them into your CRM and document how each one was built, so your team can rebuild or extend it.
The companies that fit your ideal customer criteria, with company size, industry, tech stack and hiring data, ranked by fit.
The people involved in each purchase at those accounts, with work emails verified before they reach your CRM or a sequence.
New accounts and contacts are enriched as they enter your CRM, so the next campaign starts from current data.
How it works
We turn what your sales team knows about good customers into criteria a list can be built from.
We pick the data sources that cover your market, beyond the contact databases every team uses.
We build the account and contact lists in Clay and fill in the fields your outreach needs.
We verify every email address and check each contact against your CRM, so customers and open deals stay out of the list.
Your team works the lists, or we run the outreach on them with you.
About 40 Booked calls, at last tally
Seller Candy knew who it wanted to reach, but its lists of agencies and larger Amazon sellers were built by hand over weeks and worked one message at a time, about 20 a day at best. We turned its ideal customer criteria into lists, ran sellers and agencies as separate campaigns, found the right person inside each agency and tested every email three ways. In one campaign the bounce rate stayed under 1% on every version, and the program reached about 40 booked calls.
Tools
We start with the tools you have and suggest a change only when it fixes a real problem.
We’re one of six Clay Elite Studio Partners, a HubSpot Solutions Partner and a Salesforce Partner.
Your options
Each option suits a different team. The last row says when each one is the better choice.
| Compared on | Frontal | In-house hire | Freelancer | List broker |
|---|---|---|---|---|
| Who does the work | Our GTM engineers build the lists in Clay from your criteria and write them into your CRM. | An SDR or ops hire who builds each list by hand. | A freelance researcher who builds a list to order. | A vendor selling contact lists from its own database. |
| How fast it starts | First week: kickoff and access. Month one: audit and setup. Months two and three: launch and improve. | Once the role is hired and onboarded. | As soon as you find one and agree the scope. | As soon as you buy the list. |
| What you keep afterwards | Every list and the table that built it, in your accounts and documented. | What they build, and their know-how while they stay. | The finished list, as a file. | The records you bought, under the vendor’s license terms. |
| How it’s paid for | A fee agreed in a statement of work, starting with a three-month engagement. | A salary and benefits, plus the cost of hiring. | By the hour, the day or the project. | A price per record or per list. |
| Best when | You want lists built from your own criteria, verified and kept current in your CRM. | You build new lists every week and want the skill on your team. | You need one list researched by hand, and your team takes it from there. | One database covers your market, and your team can check and load the data. |

How to start
We start with a three-month engagement. The scope, milestones and owners are written into a statement of work before anything starts, and ongoing terms are agreed before work begins.
First week
We hold the kickoff call, get access to your CRM and Clay, and agree the market and the criteria for the first list.
What you do One kickoff call, and access to your CRM and tools.
First month
We review the lists and data you have, choose the sources, and build the first list in Clay on a sample.
What you do Check the sample against what your sales team knows.
First three months
In month two we build the full lists, verify every address and write them into your CRM. In month three we review with your sales team which lists brought replies and build the next ones.
What you do Approve each list before it is used.
Ongoing
Bring your current setup, and we’ll walk you through how the first three months would look for your team.
The price depends on scope, channels and volume. We agree it in a statement of work before we start.
A B2B list is a set of companies, and the people at them, that fit who you sell to. An account list names the companies; a contact list names the buyers at each one, with verified work emails. Good lists start from your own ideal customer criteria, not from what one database happens to hold.
It is a contact list with a verified work email for each buyer, ready for outreach. We verify every address before it reaches your CRM or a sequence, because unverified addresses bounce and hurt every email after them.
It depends on the size of your market and the data sources it needs. We agree our fee in a statement of work before we start, and the data tools, such as Clay, bill their plans to you, separately from our fee.
A data provider sells records from its own database. List building companies like Frontal combine several sources, check the results against your criteria and your CRM, and build each list for the campaign you plan to run.
Yes, and some of the best lists come from places other teams don’t look, such as job posts, event attendee lists or the data inside your own product. We get the data out, cut it down to the buyers who fit and enrich it in Clay.
You do: every list and the Clay table that built it live in your accounts, documented so your team can rebuild or extend them.
Yes, if you want us to. As a list building company we can hand the lists to your team, or run email and LinkedIn outreach on them under your team’s names.
