​
Niche and complementary tools

TheirStack combines technology lookup (37,000+ technologies) with job posting analysis (171M postings from 195 countries). Their unique angle is inferring buying intent from hiring — if a company posts for a “Salesforce Admin,” they likely use Salesforce.
  • Strengths: Unique hiring signal intelligence, broad technology coverage, job-posting-based intent
  • Limitations: No verified contacts, no subscriber/churn signals, no historical data, no custom audience exports, no CRM integration
  • Best for: Teams that want to combine technographic data with hiring signals. Works well alongside TechnologyChecker.
  • Pricing: ~$109/1K credits
Bloomberry (owned by Revealera) specializes in real-time subscriber and churn detection for ~1,200 B2B products. Strong methodology using DNS, certificates, and subprocessor data, with institutional credibility as a hedge fund data supplier.
  • Strengths: Deep churn detection methodology, hedge fund client credibility, job posting data (2.5M jobs/month)
  • Limitations: Only ~1,200 technologies (vs 40,000+), no verified contacts, no custom audience exports, limited historical data (since 2019)
  • Best for: Financial analysts and investors who need high-confidence churn signals for a focused set of B2B products
  • Pricing: $199/month
An enterprise sales intelligence suite that includes technographic data alongside contact and company information. Technology detection isn’t the primary product; it’s one feature within a larger platform.
  • Strengths: Large contact database, intent data, and sales engagement tools in one platform
  • Limitations: Annual contracts typically start at $15K+, technographic depth is limited compared to dedicated tools, and technology data may lag behind specialized platforms
  • Best for: Enterprise sales teams already using ZoomInfo for contact data who want basic technographic filtering
Landbase is an agentic AI GTM platform ($42.5M funded, 825% revenue growth) that automates entire GTM workflows. Their technology directory (~20 categories) is primarily an SEO strategy, not their core product.
  • Strengths: AI-powered GTM automation, well-funded with rapid growth, 1,500+ intent signals
  • Limitations: Technology coverage limited (~20 categories), no historical data, different product category (AI automation vs. technology intelligence)
  • Best for: Teams wanting fully automated AI-driven GTM workflows rather than technology intelligence data
  • Pricing: ~$90/3K credits
Primarily contact databases that use technographic data as a filtering dimension. You can search for “companies using Shopify” as a lead filter, but the technology data isn’t as deep or historical as dedicated platforms.
  • Strengths: Strong contact data with email verification, affordable pricing, built-in outreach tools
  • Limitations: Shallow technology data (used as filter, not core product), no historical trends, limited backend detection
  • Best for: Teams that need contact data first and technology filtering as a secondary capability

​
Choosing by use case

Recommended: TechnologyCheckerOutbound sales teams need technology signals connected to verified contacts. A tool that tells you “Company X uses Salesforce” without saying who to contact just creates more research work.TechnologyChecker provides:
  • Technology data + verified decision-maker emails in one lookup
  • Real-time subscriber/churn alerts (with contacts attached)
  • Lead lists with technology and firmographic filters
  • Custom audience exports for ad platform targeting
  • CRM automation to sync data directly to your pipeline
  • Bulk enrichment for pipeline building
Alternatives: ZoomInfo (if you need a broader sales intelligence suite and have budget for enterprise contracts), 6sense (if you need AI-powered intent data at enterprise scale), Apollo.io (if contacts are the priority and technology filtering is secondary).
