Use Find Gender via the API and the MCP
Find Gender isn't tied to the Google Sheets sidebar. Every Derrick enrichment - this one included - is also exposed through the REST API and the MCP server, so you can run it from your CRM, your data pipeline, an AI assistant, or any no-code tool (Zapier, Make, n8n). Same credit cost as the add-on, same data. API access is included from the PLUS plan up.
"This app saved me so much time and effort. Great for anyone looking to build a contact list or network at scale quickly. As a start-up it's been invaluable."
Alex Clark
Director | SaaS GTM Leader
"Working pretty nifty compared to Snov.Io. Price wise it does give a fair shake, and IMO better interface since it's google sheets."
David Sire

"Derrick is a very simple and user-friendly app to enrich your contacts database. Best thing: you can test it for free. And then the price is so low, it's a no brainer."

Inferring probable gender from a first name is a small but high-leverage detail in B2B outreach : a correctly addressed opener ("Hi Sarah" / "Hi Mark") reads better than a generic salutation in the same campaign. The challenge is doing it at scale across multi-cultural lists without breaking accuracy on non-Western names.
Derrick reads the first-name column directly from Google Sheets and returns the probable gender (M / F / unknown) plus a confidence score in the next cells. The model covers 180+ countries with separate accuracy tiers per region. Free up to 100 lookups/month, no card. The use case that drives most adoption : pre-segmenting cold-email lists into M / F splits to A/B-test salutation, opening line, and follow-up tone. Higher volumes on the Derrick pricing page.
Just the Derrick Google Sheets add-on (one click, no API keys, no developer setup). Once installed, Find Gender is one of the workflows available from the Derrick sidebar inside any Sheet. The same feature is also available via REST API and via the Derrick MCP server for Claude / ChatGPT.
Can I use Find Gender on a list of 1,000+ rows?
+
Yes - Find Gender runs as a batch job inside Google Sheets, with progress tracking and per-row credit accounting. The workflow scales linearly: 10 rows or 10,000 rows, the steps are identical and you can step away while it runs.
Where does the data behind Find Gender come from?
+
Derrick aggregates 10+ public-data sources (LinkedIn graph, company websites, registry data, web crawl, third-party providers) and runs a multi-source lookup for Find Gender. The first source that returns a confident match wins; if no source is confident enough, the cell is left blank rather than guessed.
Is Find Gender GDPR-compliant?
+
Yes. Derrick only enriches public data, doesn't store personal records beyond the duration of the lookup, and supports full deletion on request. The Sheets add-on runs inside Google's OAuth-protected environment so your data stays private to your account.
Can I trigger Find Gender automatically when I add a row?
+
Yes - set up a Google Sheets onEdit trigger (Apps Script, takes 2 minutes) so a new row in column A automatically runs Find Gender into column B. Pair with Zapier / Make / n8n to push CRM contacts directly into the sheet for hands-free enrichment.
