TechSpy — Find Companies by Technology Stack

Use Cases

Built for revenue teams

Whether you're an SDR building prospect lists, a RevOps team enriching your CRM, or an agency doing competitive research — TechSpy has you covered.

🎯

SDR Prospecting

Build laser-targeted prospect lists based on the exact tools your best customers use. Stop spraying, start scoring.

"Companies using HubSpot but not Salesforce, with email contacts"

🔄

Competitive Displacement

Find companies using your competitor's platform. They're already sold on the category — you just need to show a better deal.

"All Magento stores in Europe — ripe for Shopify migration pitch"

🏢

Agency Lead Gen

Find clients running outdated stacks, slow sites, or missing key tools. Deliver a personalised pitch with data they can't ignore.

"WordPress sites without caching or a page speed tool"

🤖

AI Agent Workflows

Pipe TechSpy data into your AI agents via API. Enrich incoming leads, score ICPs, or trigger personalised sequences automatically.

"Enrich our HubSpot leads with tech stack via API — trigger sequence if they use Stripe"

📊

Market Research

Map the technology landscape of an entire vertical. Track adoption trends, find whitespace, or benchmark against competitors.

"What % of e-commerce sites in Fashion use TikTok Pixel?"

⚡

Technology Change Alerts

Get notified the moment a prospect adds or removes a technology — strike when the buying signal is freshest.

"Alert me when any company in my list adds Salesforce or Outreach"

How it works

Every signal. Every site. Every day.

TechSpy continuously crawls the web, fingerprinting technologies from headers, HTML, cookies, scripts, and JavaScript globals.

🔍

Deep fingerprint detection

880+ technology patterns matching HTTP headers, meta tags, script URLs, cookies, HTML patterns, and JavaScript globals like dataLayer and Sentry DSN.

🔎

Boolean stack filters

Combine must-have, must-not-have, and any-of filters across any technologies. Build the exact ICP profile your sales team needs.

📧

Contact data included

We crawl /contact and /about pages to extract business emails and LinkedIn profiles — so your export is ready for outreach, not just analysis.

🌍

Country & category filters

Filter by site country and business category (E-commerce, SaaS, Health, Finance, and 12 more) to narrow your ICP to the right market.

⚙️

API & AI-native

"I filtered 4,000 Shopify stores that don't use Klaviyo. That list alone closed two deals this month. Nothing else does this at this price."

Senior SDR · B2B SaaS

★★★★★

"We were paying $495/mo for BuiltWith Pro and still couldn't get contact data. TechSpy gives us emails in the export. Game changer for cold outreach."
