When to reach for it
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 10-source waterfall so you get a usable number on 40-60% of US/EU B2B contacts on the first try.
- Cold-call outbound: SDRs paste a list of 200 LinkedIn URLs, run Phone Finder, and start dialling within 5 minutes.
- ABM trigger sequences: when intent fires on a target account, get the buying-committee mobile in seconds and call within the 30-min window.
- CRM hygiene: re-enrich the phone field on stale contacts to surface the 30% that have changed since the last refresh.
- Compliance backfill: enrich the legal-contact phone field on every account before contracts hit procurement.

"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."

Dan Hughes
Founder/CEO, AlmanacIO
"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
"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
"Have tested over 10+ LI scraper apps, Derrick beats them all. Simple to use, accurate data, and affordable price."

Mobile phone numbers are the most expensive credit type across every B2B data tool — Apollo bills 8 credits per phone reveal, ZoomInfo prices its mobile-credits add-on at $0.50+ per lookup, Lusha sells phone credits separately from email. Derrick's phone-finder runs the same waterfall (Apollo + Clearbit + Cognism + Kaspr partner sources stitched together) but reads LinkedIn URLs or names+companies directly from a Google Sheet column and writes the mobile back in the next cell. Cost per phone : about $0.22 on the Pro plan — roughly 3-4× less than Apollo at full credit cost, 8-10× less than ZoomInfo's per-mobile rate.
Hit rate sits around 64 % on European contacts and 71 % on US contacts (Q1 2026 benchmark, 5K-row sample). The 30 % miss is mostly free-tier LinkedIn profiles with no mobile attached in any partner DB. Per-plan phone-credit cost on the Derrick pricing page.

Frequently asked questions
Do I need to install anything to use Phone Finder?
Just the Derrick Google Sheets add-on (one click, no API keys, no developer setup). Once installed, Phone Finder 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 Phone Finder on a list of 1,000+ rows?
Yes - Phone Finder 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 Phone Finder come from?
Derrick aggregates 10+ public-data sources (LinkedIn graph, company websites, registry data, web crawl, third-party providers) and runs them in a waterfall 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.
