Derrick App Code Promo

Derrick is a Google Sheets extension built for B2B prospecting and lead enrichment. The premise is straightforward: rather than juggling multiple tools and exporting data between platforms, everything happens directly inside your spreadsheet. You install the extension from the Google Workspace Marketplace, connect your account, and your Sheets becomes a fully functional lead enrichment and qualification workspace.

The tool's most used feature is its email finder. From a first name, last name, and company domain, Derrick automatically retrieves the professional email address of a contact and validates it in real time to reduce bounce rates before you even start an outreach campaign. The phone finder works on the same logic, surfacing direct phone numbers from the same inputs.

LinkedIn enrichment is another central feature. Derrick lets you import lead and company profiles from LinkedIn in one click, extracting structured data directly into your sheet without copy-pasting. For users with a LinkedIn Sales Navigator subscription, the tool goes further: you can import full lead search queries and account search queries, pulling up to 2,500 results per query into a clean, organized table. Standard LinkedIn profiles are also supported, without requiring a Sales Navigator account.

Beyond contact data, Derrick enriches profiles with over 50 attributes per contact and company. This includes job title, industry, company headcount, tech stack, LinkedIn bio, website, funding information, and more. The technology detection feature identifies the tools and platforms used on any given website, which is particularly useful for qualifying accounts based on their existing software stack before reaching out.

Derrick also integrates AI directly into the enrichment workflow. Using Claude and OpenAI's APIs, the platform can automate lead scoring, contact segmentation, message personalization, and profile summarization inside Google Sheets, without any technical setup. Actions can be chained together into automated sequences, all driven by simple configurations rather than code.

The tool connects natively with Zapier, Make, and n8n, which allows users to push enriched data directly into CRMs, email platforms, or any other tool in their stack once the data is ready.

• Google Sheets as the interface is a genuine differentiator: For anyone who already manages their prospect lists in spreadsheets, there's no migration, no new UI to learn, no export-import loop. You work where your data already lives, and Derrick adds enrichment capabilities on top without disrupting that workflow. This is particularly relevant for solo operators and small teams who don't want to maintain a dedicated prospecting platform.

• The price-to-volume ratio is hard to beat: At €9/month for 4,000 credits with rollover, Derrick is one of the most affordable enrichment tools on the market for what it covers. Unused credits carrying over to the next month adds flexibility that most subscription tools don't offer, and makes it easier to manage variable prospecting volumes without wasting budget.

• AI-powered enrichment built in: The integration of Claude and OpenAI APIs directly into the workflow means you can automate lead scoring and message personalization at the spreadsheet level, without connecting to an external AI tool or writing a single line of code. For a tool at this price point, that's an unusual level of capability.

• Real-time email validation: Finding an email address is one thing; knowing whether it's deliverable before you send anything is another. The built-in validation step reduces bounce rates directly at the sourcing stage, which protects your sender reputation downstream when campaigns go live.

• Rollover credits and a usable free tier: The 200-credit free plan requires no payment method to activate, which makes it genuinely useful for testing the tool before committing. And across paid plans, credits that aren't consumed in a given month roll over rather than expiring, which is a meaningful practical advantage for teams whose prospecting activity isn't perfectly linear month to month.

• No API access: For teams that want to integrate Derrick into custom workflows or internal tools programmatically, the absence of an API is a hard stop. It limits the tool to users who are comfortable working within the Google Sheets environment and the native integrations available through Zapier or Make.

• Some features require LinkedIn Sales Navigator: The most powerful LinkedIn functionalities, particularly the bulk import of lead search queries, only work if you have an active Sales Navigator subscription. That's an additional cost that needs to be factored in, and it means the full value of the tool is conditional on another paid product.

• No built-in outreach capabilities: Derrick is purely a data sourcing and enrichment tool. Once your list is ready, you still need a separate platform to actually reach out to your prospects, whether that's an email sequencing tool, a LinkedIn outreach tool, or a CRM. For users expecting an all-in-one prospecting solution, this is a meaningful gap.

• Credit consumption can be hard to predict: Depending on which features you use and how complete your input data is, credit costs per contact can vary. Running a bulk enrichment on a large list without understanding the credit model first can lead to depleting your monthly allocation faster than expected.

• Reported issues around subscription cancellation: Several users have flagged that unused credits are lost upon cancellation rather than being refunded or honored through the end of the billing period. It's worth reading the terms carefully before committing to a higher-volume plan.

Derrick operates on a credit-based model where each action (email lookup, phone number retrieval, LinkedIn enrichment, etc.) consumes one credit. Credits roll over from one month to the next on all paid plans, and the free tier requires no payment method to get started.
