Reach new websites the day they launch
CertLeads monitors the global Certificate Transparency log and surfaces every new website — with owner contact, SEO score, and platform — before anyone else knows they exist.
CertLeads is a B2B lead source that detects newly-launched websites within 24 hours using Certificate Transparency monitoring, then enriches each one with owner contact details, an SEO score, and the platform it runs on. You can browse the directory of newly-launched businesses for free; paid plans with contact reveals and bulk CSV exports start at $39 per month.
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.
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.
Flexible filters
Slice by country, category, platform, SEO score, contact completeness, freshness, and pre-launch status. Save searches and set up email alerts.
CSV export & API
Export any filtered view as CSV, or connect via REST API to push fresh leads directly into your CRM, outreach tool, or internal pipeline.
Reach the owner, not a contact form
We extract business emails and phone numbers from every lead — from the homepage, /contact page, structured data, and WHOIS. Pro tier reveals them in plaintext; Free tier shows you they exist, with the detail blurred.
Email, phone, or both. Higher for English-language markets.
Unused reveals don't roll over, but there's no per-reveal charge.
Email + phone reveals on all paid plans for the US, CA, AU, NZ, UK, Singapore, UAE & India.

FAQ
Frequently asked questions
How many leads can I export each month?
Each plan has a monthly and a daily export allowance, both counted in leads: Free 200/month (20/day), Starter 2,000/month (200/day), Growth 5,000/month (500/day), Pro 10,000/month (1,000/day), Agency 30,000/month (2,000/day). The daily figure is a throttle, not a separate budget — it stops a single account draining a day of fresh inventory in one morning. Your monthly allowance resets on your billing anniversary, not on the 1st of the month, and the daily one resets at 00:00 UTC. If an export would exceed your allowance you are told which limit applies and when it resets before anything is charged or deducted.
How many other people get the same lead?
At most 3. Every lead in CertLeads is delivered to a maximum of 3 customers, ever, and after each delivery it is held back for 10 days before it can go to anyone else — so the same new business is never sold to three people on the same morning. You also never receive the same lead twice across two exports. This is enforced in the database at the moment of export, not by a setting, which is why an export sometimes returns fewer rows than your filter matches.
Why does my export contain fewer leads than the directory shows?
Because the directory shows everything that matches your filters, while an export can only contain leads that are actually available to you. Three things hold rows back: leads already delivered to their maximum of 3 buyers, leads cooling down within 10 days of their last delivery, and leads still inside your plan's access delay. Rows you have already exported before are also excluded, so you are never sent or charged for the same lead twice. The export screen states the real number before you buy, and you are only ever charged for what will actually be delivered.
What are verification tokens and how am I charged for them?
Email verification is metered separately from your plan, in tokens: one token verifies one email address. Packs are 1,000 tokens for $5, 5,000 tokens for $20, 25,000 tokens for $80. Tokens are deducted before the check runs and automatically refunded for any address the provider could not resolve, so you never pay for a non-answer. Tokens do not expire and are separate from your export allowance — verification is optional, and every plan works fully without it.
What is your refund policy?
Monthly subscriptions carry a 14-day, no-questions-asked money-back guarantee on your first ever subscription; annual subscriptions carry 30 days. One-time CSV exports are non-refundable once the download link has been generated and emailed, except where a bug prevented the link from being generated at all — then it is a full refund. AppSumo lifetime purchases follow AppSumo's own refund policy, which is typically 60 days. Full terms are at /terms.
What do the 🟢 / 🟡 / 🔴 freshness tiers mean?
Every lead carries a freshness tier that combines how recently the site went live with whether we found a usable contact for it. 🟢 Green: Live within the last 7 days, with at least one contact method found. These are the freshest leads and the ones worth contacting first. 🟡 Amber: Live within the last 30 days, with at least one contact method found. Still recent, but more likely to have been approached by someone already. 🔴 Red: Older than 30 days, or no contact method found. Useful for research and enrichment, not for cold outreach. Exports default to Green only, because most quality complaints come from people who exported everything and judged the data by its worst rows. You can opt into Amber and Red deliberately.
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. Starter ($39/mo) adds a daily CSV of newly-launched domains and larger exports. Growth ($59/mo) unlocks up to 500 email + phone contact reveals per month and 5,000-lead exports. Pro ($129/mo) adds scheduled email delivery of your saved searches and one-hour access to new leads. Agency ($249/mo) adds instant access, 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 $39/mo 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.
