How to build a B2B lead list in Claude

Claude is good at reasoning about who your buyer is. With the Enricho connector, it can also find those buyers: real people at real companies, with contact details where they are on file. This guide walks through building a lead list from your first prompt to a finished table you can export or hand to your outreach tool.

What do you need before you start?

You need three things:

1. A Claude account on web or desktop where you can add custom connectors. Availability depends on your plan and workspace administrator.
2. An Enricho account. You create it the first time you connect, with no password and no card. The Free plan includes 100 credits a month.
3. A clear idea of your buyer: the role, seniority, industry, company size and location you sell to.

How do you add Enricho to Claude?

1. In Claude, open Settings → Connectors and choose Add custom connector.
2. Name it Enricho and paste the server URL: https://mcp.enricho.co/mcp.
3. Click Connect and sign in with your email and the 6-digit code Enricho sends.
4. In a chat, open the tools menu and make sure Enricho is turned on.

If you use Claude Code instead, run this in your terminal, then run /mcp, choose Enricho and sign in:

claude mcp add --transport http enricho https://mcp.enricho.co/mcp

Full instructions for every client are in the setup docs.

How do you describe the leads you want?

Write your request the way you would brief a colleague. Name Enricho the first time so Claude reaches for the right tools.

Use Enricho to find marketing directors and heads of marketing at
software companies in Melbourne with 51-200 or 201-500 employees.
Only people with an email.

Claude turns this into filters. Filters that take lists match any value in the list, and different filters combine with AND. The request above becomes something like:

Other useful filters include role, skills, country, has phone and has LinkedIn. If your buyer depends on something Enricho does not filter on, such as revenue or funding, Claude should say so rather than guess.

What happens before Claude spends credits?

Claude runs a free preview first. A preview returns a sample of up to 10 records without contact details, so you can check that the titles and companies look right.

Claude then shows you the targeting it used and the sample, and asks whether to fetch full records. If the sample is off, refine it:

Too many agencies in there. Keep only companies whose industry is
software, and add VP-level marketing people too.

Previews do not show an exact total number of matches, so treat the sample as a quality check, not an audience size. More on this in how credit-based pricing works for AI agents.

How do you get the full list?

When the sample looks right, approve the spend:

Looks good. Get the first 50 full records.

Each full record returned costs 1 credit, so 50 records cost 50 credits. If your balance cannot cover the whole page, nothing is returned and nothing is charged; ask for a smaller page or add credits.

Full records include name, job title, seniority, role, company, industry, company size, location, skills, emails, phone numbers where available, and LinkedIn and other social profiles. An empty field means the value is not on file.

Claude returns one page at a time. Ask for "the next page" when you want more.

How do you target specific accounts first?

Sometimes you want people at companies that meet certain criteria. Ask Claude to find the companies first, then the people:

Use Enricho to find software companies headquartered in Australia with
11-50 employees. Preview them first. Then find the founders at those
companies, only people with a LinkedIn profile.

Claude previews company_search, then passes the returned company domains to person_search with seniority set to founder and owner. You approve each paid step.

How do you leave out existing customers and contacts?

Give Claude the company domains of your existing customers, and say what to exclude:

Exclude anyone at these company domains, and anyone you already
returned to me in our earlier searches.

Exclusions work on company domains and on the person IDs from earlier Enricho results, so keep your lists in the same conversation or paste the domains in.

Previews accept only a short list of excluded domains, so the sample may include people you already know. The full search applies every exclusion.

What can you do with the list in Claude?

Because the list lives in the conversation, you can keep working with it:

1. Ask Claude to format it as a table or CSV for your CRM.
2. Group leads by company and summarise each account.
3. Draft a short first message tailored to each person’s role.
4. Ask Claude to flag records missing a phone number so you can decide how to reach them.

How much does a lead list cost?

Previews, empty results and credit checks are free. Full records cost 1 credit each. Free gives you 100 credits a month; Pro is $20 for 10,000; Growth is $49 for 100,000; and Scale is $199 for 500,000. Credit packs of 10,000 cost $20 and never expire. You can ask Claude to upgrade for you, and it returns a secure checkout link. See pricing for details.
