Phone Finder use cases
Find direct dials and mobile numbers for B2B prospects from a name + company, an email or a LinkedIn URL - straight inside Google Sheets. The Phone Finder runs a multi-source lookup across several data sources so you get a usable number on a meaningful share of US/EU B2B contacts on the first try.
01
Cold-call outbound
SDRs paste a list of 200 LinkedIn URLs, run Phone Finder, and start dialling within 5 minutes.
02
ABM trigger sequences
when intent fires on a target account, get the buying-committee mobile in seconds and call within the 30-min window.
03
CRM hygiene
re-enrich the phone field on stale contacts to surface the 30% that have changed since the last refresh.
04
Compliance backfill
enrich the legal-contact phone field on every account before contracts hit procurement.

Use Phone Finder via the API and the MCP
Phone Finder isn't tied to one surface. Every Derrick enrichment - this one included - runs in the web app and in Google Sheets, and 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 everywhere, 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
Mortgage Broker at Zero Point Mortgage
"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."
Etienne Grange
CEO Form'actions
"I have been using other expensive apps or freemium like phantombuster, but Derrick has replaced them all. I love the simplicity of the Google sheet add-in, but what is best is the efficiency it delivers."
Julien Walon Cohen
CEO & Co-founder @ Diffly | B2B Sales Advisor
"Super easy to enrich linkedin urls using this tool. Both personal and company url data can be easily enriched with a click of a button."
Zaid Bilal
RevOps Professional
"Amazing Tool, I would like to advocate this to my colleagues. So that you can get more users. Keep it Up. 5 Stars!"
Asif Hanzala
Lead Generation Specialist at IdeaPeel
"The LinkedIn scraping and email finder combo is incredibly powerful. I can build a complete prospect list with contact info in under an hour. Absolute must-have for outbound."
Michael Kim
SDR Team Lead at CloudScale
"This app is fantastic. Brilliantly created to help small and mid sized businesses."
Dan Hughes
Founder/CEO, AlmanacIO
"Have tested over 10+ LI scraper apps, Derrick beats them all. Simple to use, accurate data, and affordable price."
AJ Alexander
Opportunity Prospector
Mobile phone numbers are the most expensive credit type in B2B data : every major provider meters phone reveals separately from email and prices them at a premium. Derrick's phone-finder runs a multi-source lookup across multiple data sources but reads LinkedIn URLs or names+companies directly from a column of your list, in the Derrick web app or in Google Sheets, and writes the mobile back in the next cell. Cost per phone : about €0.35 on the Pro plan - a fraction of premium single-source providers' cost.
Mobile-number match rate on US/EU B2B is competitive with premium databases (see the accuracy chart above for the measured figure). The miss is mostly profiles with no mobile attached in any data source. Per-plan phone-credit cost on the Derrick pricing page.
Do I need to install anything to use Phone Finder?
+
No. Create a free account in the Derrick web app and Phone Finder is there, nothing to install. Prefer Google Sheets? The add-on installs in one click and Phone Finder appears in the Derrick sidebar. The same feature is also available via REST API and via the Derrick MCP server for Claude / ChatGPT.
Can I use Phone Finder on a list of 1,000+ rows?
+
Yes - Phone Finder runs as a batch job in the web app or in 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 Phone Finder 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 Phone Finder. The first source that returns a confident match wins; if no source is confident enough, the cell is left blank rather than guessed.
Is Phone Finder 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 Phone Finder 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 Phone Finder into column B. Pair with Zapier / Make / n8n to push CRM contacts directly into the sheet for hands-free enrichment.
