↓ See why technology data is the best sales signal nobody's using

You're selling to companies without knowing what they already use.

You pitch your Shopify app to stores running WooCommerce. You email about your analytics tool to companies already locked into Google Analytics 4. You waste hours on prospects who will never buy — because you don't know their stack.

Selling blind
  • Pitch your product to companies already using a competitor
  • Manually visit websites one-by-one, inspect source code, guess at their stack
  • Pay $300/mo for BuiltWith just to see technology data — no contacts included
  • No way to export a list of 'all companies using Keap' with emails
  • Miss migration signals — companies switching platforms are your best leads
With Technology Lookup
  • See every technology any website uses — CMS, analytics, payments, marketing tools
  • Search 987 tracked technologies across 1.16M+ domains instantly
  • Export verified contact emails alongside technology data — not sold separately
  • Build targeted lists: 'All WordPress sites using WooCommerce' — with owner emails
  • Spot competitor displacement opportunities before your rivals do

Here's how the lookup → filter → export flow works ↓

Three steps. Two minutes. Every company using the tech you care about.

No manual website inspections. No per-lookup credits that run out mid-campaign.

1
Pick a technology

Search 987 tracked technologies — from WordPress and Shopify to Keap, HubSpot, Stripe, and Google Analytics. Select the one you want to target.

2
See matching domains

Instantly see every domain in the database running that technology. Google Analytics: 82,466 domains. WordPress: 81,806 domains. Shopify, Vue.js, Font Awesome — full counts for every tech.

This isn't just a lookup tool. Here's what makes it a prospecting engine ↓

Capabilities

Technology data is only useful when it comes with contact data.

Most tech lookup tools show you what a site runs. This one shows you who to email about it.

Full Stack Detection

987 technologies across every category — CMS (WordPress, Shopify, Squarespace), analytics (GA4, Mixpanel, Segment), payments (Stripe, PayPal), marketing automation (HubSpot, Keap, ActiveCampaign), and more. See the complete picture, not just the obvious tools.

Verified Contact Emails

Every domain comes with verified email contacts — not the noreply@ and support@ addresses that go nowhere. Over 100 generic patterns are filtered out automatically. You get one primary decision-maker email per domain, ready to use.

Multi-Channel Contact Data

Beyond email, get LinkedIn, Facebook, Instagram, Twitter, and YouTube profiles for each domain. Six contact channels per company — reach them wherever they're most active.

Bulk CSV Export

Export up to 9,900 domains per batch file. Select any technology, generate the export, and download CSV files ready for your CRM or outreach tool. No per-lookup credits, no rate limits on downloads.

Domain Authority Ranking

Every domain includes an authority rank score. Target high-traffic sites that are worth more, or focus on smaller domains where you're more likely to get a reply. Sort and filter by rank to build exactly the list you want.

Find Companies By Tech Stack

Works on any domain, any technology

I was selling CRM software to companies that already had one

My outreach was solid. The copy was good. My lists were "targeted." But I kept getting the same reply: "We already use Salesforce." Or HubSpot. Or Pipedrive. I was wasting 40% of my outreach on companies that would never switch because they'd just signed a 2-year contract.

The problem wasn't my pitch — it was my targeting. I was filtering by industry and company size, but those filters don't tell you what tools they already run. A 50-person SaaS company using Salesforce is a completely different prospect than one using a spreadsheet.

So I built a database that maps technologies to domains — and then maps those domains to real contact emails. Not a lookup-by-lookup service that charges per query. A bulk system where you pick a technology and get every company using it, with emails, ready to export.

1.16 million domains and 987 technologies later, this is the targeting layer that should have existed from the start.

Common questions

BuiltWith shows you what technology a website runs — and charges $295-$495/mo for it. This tool does the same thing and includes verified contact emails, social profiles, and bulk CSV export. You get technology data and contact data in one place, at a fraction of the cost.

987 technologies across every major category: CMS platforms (WordPress, Shopify, Squarespace, Wix), analytics (Google Analytics, Mixpanel, Segment), payment processors (Stripe, PayPal, Square), marketing automation (HubSpot, Keap, ActiveCampaign, Mailchimp), JavaScript frameworks (React, Vue.js, Angular), and more. If a website uses it, we probably track it.

Over 100 generic email patterns are filtered out automatically — noreply@, support@, billing@, legal@, privacy@, unsubscribe@, and dozens more. What remains is de-duplicated to one primary email per domain, matched against the domain to ensure it belongs to that company, and classified as either a direct contact or a last-resort address. You get clean data, not a raw dump.

Yes. You can filter domains by technology stack — for example, "WordPress sites also running WooCommerce and Stripe." This lets you build hyper-targeted lists of companies with specific technology combinations, not just single-tech lookups.

Standard CSV, batched into files of up to 9,900 domains. Each file includes domain name, domain rank, detected technologies, primary email, and available social profiles (LinkedIn, Facebook, Instagram, Twitter, YouTube). Drop them straight into your CRM or outreach tool.

Over 1.16 million domains with full technology and contact data. The underlying data source covers 48M+ domains — we surface the ones with verified contacts and technology associations so every record you export is actionable, not filler.
