🇫🇷 SIRET/SIREN/Name Enrichment use cases
Enrich French companies from a SIRET, a SIREN, or just a company name, with directors, revenue, headcount, address, legal status and 30+ registry fields - direct from the official French government data sources. A number resolves exactly; a name is matched to the closest company with a confidence score and the matched name, so you can trust or filter each row.

02

validate that a French inbound is a real registered company (vs. a freelancer).
Use 🇫🇷 SIRET/SIREN/Name Enrichment via the API and the MCP
🇫🇷 SIRET/SIREN/Name Enrichment 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
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

Michael Kim
SDR Team Lead at CloudScale

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
French B2B prospecting runs on SIRET / SIREN - the legal company identifiers that unlock director names, revenue, headcount, sector code, and registered address (data that's public via INSEE but never bundled into international enrichment tools). The catch: most of the time you don't have the number, you have a company name. Teams then look it up by hand on Societe.com, one company at a time.
Derrick reads a column of SIRET, SIREN or plain company names from Google Sheets and returns 30+ official legal data points in the next cells - current directors, declared revenue, employee headcount, NAF sector, registered address, last balance-sheet date. A number resolves exactly; a name is matched to the closest company and comes back with the matched name and a confidence score, so you trust the sure rows and filter the rest. Add an optional département to disambiguate common names. Free up to 100 lookups/month, no card. Data from the official recherche-entreprises.api.gouv.fr registry. Per-call cost on the Derrick pricing page.
Do I need to install anything to use 🇫🇷 SIRET/SIREN/Name Enrichment?
+
Just the Derrick Google Sheets add-on (one click, no API keys, no developer setup). Once installed, 🇫🇷 SIRET/SIREN/Name Enrichment 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 🇫🇷 SIRET/SIREN/Name Enrichment on a list of 1,000+ rows?
+
Yes - 🇫🇷 SIRET/SIREN/Name Enrichment 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 🇫🇷 SIRET/SIREN/Name Enrichment 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 🇫🇷 SIRET/SIREN/Name Enrichment. The first source that returns a confident match wins; if no source is confident enough, the cell is left blank rather than guessed.
Is 🇫🇷 SIRET/SIREN/Name Enrichment 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 🇫🇷 SIRET/SIREN/Name Enrichment 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 🇫🇷 SIRET/SIREN/Name Enrichment into column B. Pair with Zapier / Make / n8n to push CRM contacts directly into the sheet for hands-free enrichment.
