What is ZoomInfo?
ZoomInfo is a comprehensive B2B intelligence platform that combines contact data, company information, intent signals, and sales automation into a single enterprise platform. With 321M+ professional profiles, it's primarily used by sales and marketing teams at mid-market and enterprise companies for prospecting and outreach.
TheirStack is built for a different purpose — real-time job data and technographic intelligence. 100% of our effort goes into building a high-quality job data and technographic platform.
Pricing and access
- ZoomInfo pricing typically starts at $15,000/year and can reach $50,000+/year depending on the package and number of seats
- Access requires a sales process with demos, negotiations, and annual contract commitments
- There is no free tier or self-serve option — you can't test the data before buying
TheirStack offers a free tier with 50 company credits/month, and paid plans start at $59/month. You can also buy credits as a one-time purchase — no subscription needed. Buy a credit pack, use it within 12 months, and you're done. You can sign up, explore the data, and integrate the API without talking to anyone.
Technographic data approach
ZoomInfo includes technographic data as one feature among many in its platform. Technology detection is not its core focus, and accuracy can vary compared to dedicated providers.
TheirStack detects technologies from job postings, which reveals both frontend and backend technologies — including databases, DevOps tools, ERPs, and programming languages that website scanners can't see. Every technology signal is traceable to the actual job posting, so you can verify why we say a company uses a specific technology.
Job data and hiring signals
ZoomInfo does not provide a dedicated jobs API. TheirStack offers real-time access to job postings from 323k sources with 40+ filters, built-in deduplication, and sub-second response times. Job data serves as a powerful intent signal — when a company posts 5 Kubernetes engineer positions, that's a concrete buying signal for container orchestration tools.
UI and contact data integrations
- Beyond the API, TheirStack provides a rich UI where you can run company and job searches and quickly find people contacts from selected companies.
- We integrate with leading contact data providers (Apollo, ContactOut) and LinkedIn (Free, Recruiter, Sales Navigator) to streamline outreach from search results.
Extensive filtering capabilities
- Company filters (TheirStack): By industry, size, country, revenue, funding, URL, LinkedIn URL or slug, etc.
- Job filters (TheirStack): By title, description, country, city, remote options, salary, etc. Regular expression filters are supported by many fields like title, description or locations.
ZoomInfo offers company and contact filters but lacks deep job-level filtering since it's not a job data platform.
When to choose each
Choose ZoomInfo if you need an all-in-one sales platform where technographics are just one piece of a larger sales workflow that includes contact data, automation, and CRM integration — and your budget supports $15K+/year.
Choose TheirStack if you need focused technographic intelligence with job data, want self-serve access with developer-friendly APIs, or can't justify enterprise pricing for features you won't use.
