ZoomInfo vs Seamless.AI vs Derrick in short. ZoomInfo: enterprise B2B contact and company data. Seamless.AI: real-time AI search engine for sales leads + Chrome extension contact finder. Derrick is a B2B enrichment web app (nothing to install), also available as a Google Sheets add-on, a REST API and an MCP server (Claude and ChatGPT drive enrichment for you). It is free forever with 100 credits/month, with paid plans from €20/month, and it runs on its own or alongside ZoomInfo or Seamless.AI.
ZoomInfo is a B2B database vendor - seat-time + record access charged per user, per year. The side-by-side comparison below tracks ZoomInfo's total-cost-of-ownership across team growth and lookup volume against Derrick's credit-pool model where the cost moves with usage, not headcount.

Why teams pick Derrick over ZoomInfo and Seamless.AI
3 core reasons SDRs and ops teams switch to Derrick. Click to expand each.
01
Real-time validation without manual data upkeep
＋
Derrick delivers real-time email validation in the web app (or in Google Sheets, Claude and the API), a capability that ZoomInfo and Seamless.AI don’t provide as a native, end-to-end web-app-first solution. Unlike Seamless.AI’s rapid prospecting focus, Derrick eliminates manual upkeep by validating contacts on the fly as you type, without leaving the web app or your sheet. This reduces bounce and improves deliverability, saving 5-10 hours per month of manual verification for teams. A practical use case is auto-validating new leads during list building, ensuring only deliverable emails move forward.
02
Flexible, unlimited 3rd-party integrations for automation
＋
Derrick addresses the limited integration abundance seen with ZoomInfo and Seamless.AI, which often acts as data providers rather than flexible automation platforms. Unlike those tools, Derrick offers flexible, unlimited third-party integrations for automation directly in the web app (or in Google Sheets, Claude and the API), enabling seamless workflow orchestration. Clients typically save 5-10 hours per month by automating data flows across tools without export hassles, while leveraging 3,000+ integrations via Zapier/Make/n8n. A quick use-case: auto-update prospect lists from a CRM into Sheets and trigger follow-up tasks without manual steps.
03
Fast, accurate data quality without manual validation bottlenecks
＋
Derrick addresses the slow, error-prone data quality seen with ZoomInfo and Seamless.AI, where real-time validation often still relies on manual checks or secondary verification steps. Unlike those platforms, Derrick delivers fast, accurate data quality with built-in real-time validation directly in the web app (or in Google Sheets, Claude and the API), reducing manual bottlenecks. Teams save time and improve deliverability, with up to 5-10 hours per month reclaimed per user and higher confidence in contact accuracy. A quick-use case: enrich a batch of 200 leads and validate emails instantly within your existing sheet, without leaving Derrick.

What’s the Derrick vs ZoomInfo main difference for outreach?
+
The core difference lies in approach: ZoomInfo functions as a standalone B2B database requiring external tools for actual outreach campaigns, while Seamless.AI offers real-time contact verification with limited enrichment depth. Derrick operates natively in the web app (or in Google Sheets, Claude and the API), transforming it into a complete prospecting hub without external platforms or CSV exports. You get fifty plus enrichment attributes, integrated AI scoring with Claude and ChatGPT, real-time email validation, and rollover credits monthly. Unlike ZoomInfo's enterprise pricing and Seamless.AI's usage-based scaling, Derrick starts free with no credit card required, making personalized outreach automation accessible immediately without platform switching or complex integrations.
Is Derrick a better alternative to ZoomInfo for small teams?
+
Derrick can be a strong alternative to ZoomInfo for small teams, particularly if you prioritize ease of use and cost efficiency. While ZoomInfo is built as a comprehensive B2B database with enterprise-scale coverage, it requires significant onboarding and carries higher pricing. Derrick operates natively in the web app (or in Google Sheets, Claude and the API), eliminating complex integrations and CSV exports, and includes AI-powered enrichment with Claude and ChatGPT for scoring and segmentation. For small teams seeking lightweight, flexible data enrichment without steep learning curves or enterprise commitments, Derrick offers better accessibility and faster time-to-value than ZoomInfo's more rigid infrastructure.
Derrick vs ZoomInfo vs Seamless.AI: which is the best comparison?
+
Choosing between Derrick, ZoomInfo, and Seamless.AI depends on your specific workflow and budget. ZoomInfo is built as a comprehensive B2B database with extensive data coverage and enterprise integrations, but carries higher costs and complexity. Seamless.AI offers real-time contact verification and AI-powered insights, ideal for rapid prospecting but with steeper pricing scaling. Derrick stands out for teams prioritizing simplicity and cost efficiency, operating natively in the web app (or in Google Sheets, Claude and the API) without requiring LinkedIn Sales Navigator or complex setup. If you need massive data scale, ZoomInfo wins. For speed and accuracy, Seamless.AI delivers. For flexibility, affordability, and seamless workflow integration without technical overhead, Derrick offers superior value, especially for mid-market teams seeking lightweight enrichment without enterprise commitments.
How does ZoomInfo compare to Seamless.AI for data enrichment?
+
For data enrichment, ZoomInfo and Seamless.AI both focus on delivering verified contact data and rapid prospect discovery, but they serve slightly different needs. ZoomInfo offers a massive, highly accurate B2B database with extensive firmographic and technographic data and strong CRM integrations, making it ideal for broad prospecting at scale. Seamless.AI emphasizes real-time verified contacts and fast outreach, with strong ease of use and chrome extension advantages, but its enrichment depth leans more toward contact-level data than deep company profiles. Derrick differentiates by being a web app (also in Google Sheets, Claude and the API) with 50+ enrichment attributes per contact, real-time email validation, and seamless Zapier/Make integrations, enabling personalized outreach and automation without exporting data or complex setups. If you’re choosing between ZoomInfo and Seamless.AI for enrichment alone, consider whether you need enterprise-scale company insights (ZoomInfo) or rapid, lightweight contact enrichment for faster outbound (Seamless.AI); Derrick can complement either by enabling enhanced outreach workflows directly in the web app (or in Sheets, Claude and the API) with flexible, rollable credits and AI-driven scoring.
Does Seamless.AI pricing beat Derrick’s free tier value?
+
Seamless.AI's pricing doesn't necessarily beat Derrick's free tier value proposition. While Seamless.AI charges for access to verified contacts and AI insights, Derrick offers 100 free credits monthly with no credit card required, enabling immediate data enrichment directly in the web app (or in Google Sheets, Claude and the API). Seamless.AI excels at real-time contact verification, but Derrick's integrated AI capabilities with Claude and ChatGPT, combined with rollover credits and web app functionality (also in Google Sheets, Claude and the API), provide substantial value for teams seeking lightweight, cost-effective prospecting without platform switching or complex integrations.
Can Derrick replace both ZoomInfo and Seamless.AI for enrichment?
+
Derrick cannot fully replace both ZoomInfo and Seamless.AI for enrichment in all cases, but it complements them effectively. ZoomInfo and Seamless.AI specialize in wide, real-time data discovery and verified contacts at scale, which Derrick does not aim to replicate as a standalone database. Derrick, however, enriches data directly in the web app (or in Google Sheets, Claude and the API) with 50+ attributes per contact, real-time email validation, and AI-driven scoring, segmentation, and summaries, all without exporting to CSV or configuring external systems. For teams needing broad vetted data plus advanced enrichment workflows, using Derrick alongside ZoomInfo or Seamless.AI often yields the best results.
