What is Leadbase?

Leadbase is an AI lead generation, company research and contact enrichment platform. It helps you discover accounts, understand why they fit your offer and bring the results into a sheet you can continue working with.

The Leadbase MCP server connects that research workflow to compatible AI assistants, including ChatGPT, Claude, Claude Code, Codex, Cursor and Cline. Describe the result in ordinary language, then let your assistant use Leadbase to create a list, research existing records or retrieve findings and supporting sources.

Think of the output as a working prospect list. Each company, person, product or public content item has its own row. Research fields become columns. Your team can inspect the evidence, correct a value, add a qualification question and export the shortlist when it is ready.

This repository provides the shared integration bundle for those workflows. A single hosted service connects your assistant to your existing Leadbase workspace and sheets.

Why teams choose Leadbase

Describe the customer you actually want

Your ideal customer may be a regional manufacturer, a specialist installer or an agency serving one particular market. Describe the services, business model, location and evidence that make an account relevant. Turn your ideal customer profile into a research brief your assistant can act on.

Understand why an account belongs on your list

A company name is a starting point. Add the details that explain fit: a relevant service, a commercial customer focus, a public hiring signal or a branch network. Keep the explanation and available source links beside the account, so a teammate can understand your reasoning when reviewing the list.

Bring company research and contact research together

Build your account shortlist, then research the professional roles that matter for your offer. You can also create a dedicated people list when the person is your starting point. Keep the company context close to the contact, so your next conversation starts with something relevant.

Keep the work useful after the first answer

Your list stays in an editable Leadbase sheet. Revisit it, enrich another field, filter the results or export the accounts you want to pursue. The first research request becomes a foundation for the next one.

Features and practical benefits

DACH lead generation

Leadbase is useful for teams researching companies in Germany, Austria and Switzerland, including German SMEs, regional service providers and craft businesses. Start with a specific territory and the kind of customer your offer is built for.

For a DACH prospecting project, you might describe:

• Solar installers in Bavaria with evidence of commercial projects.
• HVAC service companies in Austria that offer maintenance contracts.
• Swiss manufacturers advertising a relevant public job opening.
• Independent kitchen retailers in Germany with multiple showrooms.
• Industrial service providers in a defined German sales territory.

These are research briefs you can adapt to your own market. Decide which details would make the result useful, then include those fields in your request. For a local sales campaign, that could be the business address and service area. For account-based sales, it could be customer segments, relevant services and professional roles.

Leadbase also supports research outside DACH. Specify the country, language context and target criteria when researching another region.

Who uses Leadbase?

From your first request to a qualified list

1. Define the result

Start with the entity you want: companies, professional contacts, products or public content. Add the number of results, geographic scope and fields that matter. A clear brief gives your assistant a concrete outcome to work toward.

Find 10 independent coffee roasters in Berlin. Include the company name, official website, location and evidence that they supply cafes or restaurants. Save one company per row in a new private sheet.

2. Connect the intended workspace

Complete the Leadbase sign-in flow in your supported client and choose the workspace you want to use. You can ask the assistant to show your accessible sheets or check the credit balance before starting research.

3. Follow progress and inspect the findings

Research can continue after the first tool response. Ask your assistant to follow the operation, retrieve its results and show the sheet. Review the source links for the criteria that matter to your decision.

4. Add your qualification questions

Once the list exists, enrich the same rows with another field. For example, research whether each roaster offers wholesale supply, training or equipment support. Your list becomes more useful as the questions become more specific to your offer.

5. Review and use the shortlist

Edit values, filter your sheet and export the accounts you want to pursue. Keep the sheet for follow-up research when your campaign develops or a teammate needs more context.

New rows or enrichment?

Use new-list research when you want additional entities, such as 50 new companies or 20 professional contacts. Each entity becomes a new result row.

Use enrichment when the entities already exist in your sheet and you want to learn something else about them. You can research selected records or an entire column. The standard column workflow preserves populated values and skips cells already undergoing research.

Research questions that reveal customer fit

The most valuable field is often the one that reflects how you sell. Before adding a research column, ask which answer would change your decision about an account.

Request both the conclusion and the supporting source. A finding such as “commercial projects mentioned on the services page” is easier to review when the source stays attached
