Describe the technology your ICP runs on
Add the specific tool or technology in the prompt field, and Sculptor sources matching companies from Clay's B2B company data filtered by tech stack.
Sculptor sources and enriches each matched company
Sculptor scans Clay's company database for businesses running your target technology, filtered by industry, headcount, and geography, then waterfalls through 150+ providers to find a verified CTO email on matched rows.
Get your tech-filtered list with CTO emails
The finished table has company name and, for rows the waterfall enriched, a verified CTO email. Push to Smartlead, Instantly, or your sequencer to trigger a campaign the moment a row lands.
Why Clay for finding companies by tech stack
Document-level tech detection via HG Insights
Get install-verified company lists from HG Insights, which reads SEC filings, RFPs, contracts, and job postings across 22,000+ technologies. Web crawlers miss mission-critical back-office tools; HG Insights catches them.
Multi-filter ICP targeting on matched accounts
Pinpoint your ICP with concrete filters: industry, headcount, revenue, geography, install age, and renewal timing. Layer technographic and firmographic criteria in one Clay table to cut the list to high-fit accounts only.
Waterfall contact enrichment for verified CTO emails
Get verified emails for matched rows. Clay waterfalls through 150+ providers in sequence and only charges credits when one returns a hit, keeping coverage high on common B2B titles like CTO.
Auto-refresh and CRM sync on new adopters
Set a recurring schedule so newly detected installs flow into your table automatically. Push enriched rows to HubSpot or Salesforce the moment a company adopts your target technology.
Our most successful campaigns are built on data that doesn’t exist in off-the-shelf tools. Clay helps us find those signals — and transform ambitious ideas into executable, high-performing campaigns.
Frequently asked questions
How does Sculptor find companies by tech stack?
Sculptor queries HG Insights, which tracks over 22,000 technologies across 12 million companies by analyzing job postings, contracts, and RFPs. You type a target technology like Salesforce or Workday, and Sculptor returns every company confirmed to run it. It then applies waterfall enrichment across multiple contact-data sources to attach a verified VP of Sales email to each matched account.
How accurate is the technographic and contact data returned?
HG Insights reports 92 to 100% accuracy on technology installations, verified through multi-source triangulation of billions of documents. For VP of Sales emails, Clay's waterfall enrichment queries multiple providers in sequence, pushing email coverage from roughly 30% to 80% or higher. You only pay per successful match, not per lookup, so low-confidence results don't cost you.
Can I find companies by tech stack in bulk?
Yes. Paste a list of target technologies, upload a CSV, or pipe data from an existing Clay table, and Sculptor processes every row automatically. Each result returns a company name and VP of Sales email you can push directly into HubSpot, Salesforce, or a sequencer like Outreach or Smartlead to launch tech-triggered outbound at scale.
Is it legal to use technographic data for B2B outreach?
GDPR permits B2B prospecting under legitimate interest (Article 6(1)(f)) when the message is relevant to the recipient's professional role and includes a clear opt-out. CAN-SPAM requires an unsubscribe link in every commercial email. In the US, California's CCPA no longer exempts B2B contact data, and 20 states now enforce comprehensive privacy laws as of 2026.
Always include an opt-out mechanism, maintain a suppression list across your CRM and sequencer, and check the rules for your jurisdiction before launching outreach.
