## What Derrick does

Derrick is a B2B data enrichment platform. Describe your ideal customer in plain language or bring your own list, and Derrick finds professional emails, phone numbers, LinkedIn data, company info, SIRET/SIREN registry data, tech stacks and more. Built-in AI (Claude / OpenAI) runs a prompt on every row.

## Four surfaces, one engine, one credit balance

- **Web app** (https://app.derrick-app.com) - the main entry: nothing to install, create a free account and start a list
- **Google Sheets add-on** (https://workspace.google.com/marketplace/app/linkedin_email_phone_finder_ia_%E2%80%94_derrick/3746789989?flow_type=2) - the same actions from a sidebar in your spreadsheet
- **MCP server** - run Derrick from Claude, ChatGPT or any MCP client (https://derrick-app.com/mcp)
- **REST API** - call the same engine from your own stack (https://app.derrick-app.com/api-docs)

## Why teams choose Derrick

- **100+ data points** on companies & leads (emails, phones, LinkedIn, firmographics, tech stack)
- **AI-powered** - built-in AI, no separate subscription
- **Nothing to learn** - describe who you want, get the list
- **Best value** - same quality data for a fraction of the cost

## How it works

1. **Start where it suits you** - the web app, a spreadsheet, your AI assistant or your own code
2. **Choose an action, give it an input** - email, phone, company, a prompt: the same actions on every surface, priced the same way
3. **Get the answer where you asked** - your list fills in, your assistant answers in the chat, the API returns JSON. Derrick says when it found nothing instead of guessing

## Data you can trust

- 24h refresh cycle from multiple sources
- 100% public-data only (GDPR compliant - Derrick doesn't stock data)

## Frequently Asked Questions

### Do I need a LinkedIn Sales Navigator account?

Some features require Sales Navigator (importing leads from a Sales Navigator search), but most don't. Email Finder, Phone Finder, and LinkedIn enrichment work with classic LinkedIn URLs.

### What's in the LinkedIn enrichment?

Firstname, lastname, fullname, location, headline, summary, current job title, previous job titles, education, languages, skills, public profile URL, company name, company LinkedIn URL - all in 1 click.

### How many leads can I import from a Sales Navigator query?

Up to 2 500 (LinkedIn's per-query maximum). Derrick imports what's shown on the page.

### Does Derrick work on Excel?

Not directly. Save your Excel file as CSV and import it into the Derrick web app (or open it in Google Sheets), enrich it, then export the result as CSV to reopen it in Excel.

### Does Derrick find lead's emails?

Yes. Give it a fullname plus a company name (or company LinkedIn URL) and Derrick returns the verified professional email address.
