How it works
Automated from cert to contact
Every TLS certificate issued anywhere in the world flows through public logs. We watch them, so you don't have to.
- 01
Certificate Transparency logs
Every new website must register a TLS cert. These are publicly logged within seconds of issuance — we stream them in real time.
- 02
Resolve, scrape, classify
We visit the domain, extract title, description, platform fingerprint, and on-page contact signals within minutes of launch.
- 03
Score, enrich, surface
SEO signals scored, business email and phone appended, category classified. Your feed updates live with full metadata.
- 04
You reach out first
Filter by country, category, platform, or SEO score — then contact, save, or exclusively claim the lead before any competitor.
Features
Everything to close before they know you're coming
Real-time CT feed
New websites surface in your feed within 2 hours of their TLS certificate being issued — hours or days before they appear in search indexes.
Contact reveal
Business emails and phone numbers extracted from homepages, /contact pages, WHOIS records, and structured data. 68% coverage across all leads.
SEO signal scoring
Every lead scores 0–100 across title tag, meta description, H1 structure, mobile viewport, sitemap, and schema markup. Filter for the most prepared buyers.
Exclusive claim
Enterprise teams can arrange an exclusive hold on high-value leads, coordinated with our team — so a lead you're working stays yours.

Frequently asked questions
What is CertLeads?
CertLeads is a B2B lead source that finds businesses the moment they launch a website. It detects newly-registered domains within 24 hours and enriches each one with owner contact details, an SEO score, and the platform the site is built on — so you can reach new companies before your competitors know they exist.
How fresh is the data?
New websites appear in CertLeads within 24 hours of going live. We monitor the global Certificate Transparency log in near real time, so a domain is typically surfaced the same day its SSL certificate is issued — long before it ranks in Google or shows up in traditional lead databases.
How does CertLeads detect new businesses?
CertLeads watches Certificate Transparency logs — the public, append-only record every SSL certificate authority must publish. When a brand-new domain gets its first certificate (which almost always happens the day a site launches), we capture it, verify the site is live, and enrich it with contact and technology data.
Which countries are covered?
CertLeads surfaces newly-launched websites worldwide. Native owner-contact enrichment is available across eight markets: the United States, Canada, Australia, New Zealand, the United Kingdom, Singapore, the United Arab Emirates, and India.
How is this different from a lead database?
Traditional lead databases sell the same aged company records to everyone, and a business only appears months or years after it launches. CertLeads is the opposite: it is a live feed of businesses that launched today, not a static list. You reach founders while they are actively setting up tools, hiring, and buying — the highest-intent window there is.
What is included in each plan?
Free lets you browse the directory and see lead metadata. Domain Feed ($29/mo) adds a daily CSV of newly-launched domains and larger exports. Pro ($79/mo) unlocks up to 500 email + phone contact reveals per month and 5,000-lead exports. Enterprise ($299/mo) adds higher limits, API access, exclusive lead holds, and a Data Processing Agreement.
Is there a free tier?
Yes. You can browse the CertLeads directory of newly-launched businesses for free, with no credit card required, and see metadata and SEO scores for every lead. Paid plans start at $29/month when you need contact reveals, daily feeds, or bulk CSV exports.
Can a business ask to be removed?
Yes. Any business can request removal from the CertLeads directory through our public opt-out form, and verified requests are honored across the directory, exports, and API.
