Clay is a multi-source data aggregation tool used by Asymmetric to build highly specific prospect lists. It functions as a more targeted and cost-effective alternative to ZoomInfo, particularly for B2B clients targeting niche audiences or complex buyer personas.
Clay uses a waterfall methodology: given a search query, it queries a sequence of 10–15 data sources (e.g., LinkedIn, Crunchbase, Apollo) one at a time. As soon as a source returns a result for a given record, it stops — you only pay when data is found, not for failed lookups.
The output is a structured spreadsheet of contacts enriched with whatever fields you requested: name, title, company, email, phone, LinkedIn profile, and more.
This makes it significantly more efficient than tools that charge per lookup regardless of result quality.
Clay supports a wide range of enrichment types beyond basic contact info:
Person-level enrichments:
- LinkedIn profile summary
- Twitter/X handle
- Event attendance or keynote history
- Email address (verified)
- Job change signals and promotions
Company-level enrichments:
- Crunchbase data: funding history, last raise date, investor list
- Job posting volume (current vs. prior year — useful for identifying stagnating companies)
- Website traffic estimates
- Instagram presence
- Company logo (useful for personalized outreach)
- Founded date, headcount, revenue model
Signals (intent proxies):
- Recent job changes
- Active job postings
- Funding rounds
- Promotion activity
These signals enable targeting based on behavioral and situational context, not just firmographic filters — a meaningful advantage over ZoomInfo's intent categories, which apply at the company level and lack specificity for niche products.
| Dimension | ZoomInfo | Clay |
|---|---|---|
| Cost | ~$1,200–$1,500/mo (direct) | ~$350/mo for 10k credits |
| Intent targeting | Company-level, ~15 categories | Signal-based, highly configurable |
| Specificity | Broad categories | Custom multi-signal queries |
| Labor intensity | High (manual filtering) | Moderate (setup + run) |
| Data sources | Proprietary | 10–15 sources via waterfall |
| Pay model | Flat subscription | Pay-per-result (tokens) |
ZoomInfo's intent feature was assessed as probably not worth it for clients with niche or novel product categories — intent categories are too broad to surface meaningful buying signals for products like reverse ATMs, where no standard category exists.
A company that had job openings last year but doesn't this year, and hasn't raised money recently, may be experiencing revenue stagnation — a strong signal for a marketing services pitch. Clay can operationalize this logic as a reusable query.
Asymmetric maintains a Clay subscription at approximately $350/month for 10,000 credits. Credits can be shared with clients on a pass-through basis (e.g., 300 credits for ~$50), allowing clients to trial the tool before committing to their own subscription.
Credits roll over and accumulate when not fully used in a given month, making the shared model viable for lower-volume use cases.
Clay has a steep learning curve. Asymmetric's internal operator (Jacob) manages list-building for both internal prospecting and client engagements. For new clients, the recommended onboarding path is:
