Fifteen years selling in B2B. Convincing people is the job — that part I knew. The real obstacle was elsewhere: knowing who to call.
Whole mornings retyping addresses from Google Maps. Guessed emails bouncing back. Purchased files where half the contacts had changed jobs.
DataCloser does in minutes what I did by hand for years. Not another platform to learn — the shortcut I wish I'd had.
Goal: make B2B prospecting accessible to small businesses. Our story
DataCloser queries Google Search and Google Maps in real time at the moment of your search, then analyzes each company's website. No resold databases, no stale data: every lead has a freshness date.
Yes. The collected data is public and professional (B2B). Email enrichment is done through a GDPR-certified provider, and every export states the source and collection date. Emails sent via Outreach automatically include an unsubscribe notice.
Connect your mailbox (Gmail, Outlook, OVH…) via SMTP in the Outreach settings. Select a lead file, write your template with dynamic variables and launch. The AI drafts a personalized email for every lead using their icebreaker, checks coherence before sending, and sends from your own address with a randomized anti-spam delay. 1 credit = 1 sent email. Follow-ups (day +4, +9, +14) are free.
Yes. The automatic follow-up on day +4/+9/+14 is free on all plans — no extra credit is charged. It's written by the AI in a different style from the first email, with a natural reminder tone.
You only pay for usable leads. 1 credit is only deducted when a lead is delivered with a usable email (personally verified or likely catch-all) — along with the decision-maker, the /10 score and the icebreaker. Leads without a valid email, leads rejected for low score, or an interrupted scan are never charged. With 500 credits, the Starter plan covers intensive prospecting across multiple sectors and cities.
Belgium, France, Luxembourg and Switzerland with native coverage, city by city. Manual input also lets you target any other country.
Yes. Through the Exports & CRM tab you can send your leads to any CRM or automation tool via webhook (Make, Zapier, n8n…), alongside the classic CSV export.
None. Plans are monthly and cancellable anytime, and one-off credit packs without subscription start at €9.99.
Most tradespeople, shop owners and local small businesses have no active LinkedIn profile. DataCloser starts from Google and their own website, where these companies actually exist.
By hand: three to four hours of searching, plus verifying the emails. With DataCloser you launch the search and the leads arrive enriched, scored and ready to contact.
Three main causes: invalid addresses generating bounces, too brutal a starting volume, and missing SPF, DKIM and DMARC configuration. DataCloser excludes unverified addresses, spreads sending across a controlled window and guides you through domain setup.
Yes. Most French-language B2B databases stop at the French border. DataCloser natively covers Belgium, France, Luxembourg, Switzerland and the Netherlands, and detects each prospect's language to write the opener in it.
Yes, in B2B under legitimate interest (Art. 6-1-f GDPR), provided you state the source of the data and allow one-click unsubscribe (Art. 14). DataCloser inserts both automatically.
