Greenway vs ZoomInfo
ZoomInfo gives you a database. Greenway gives you a system that learns your market.
Feature-by-Feature Comparison
| Feature | ZoomInfo | Greenway.ai |
|---|---|---|
| Annual pricing | $15,000–$40,000+/year | Fraction of one SDR's cost |
| Learning loop | None — static database, same results every query | Gets smarter daily from reply data; ~5% reply rate on Day 1 to ~45% by Day 90 |
| Autonomous operation | Manual — you build lists, run searches, export CSVs | Runs daily without prompting; delivers leads to CRM and Slack |
| Contact database | ~260M contacts, strong US coverage | 270M+ contacts with verified emails and phone numbers |
| Buying signal detection | Intent data based on web traffic; limited to Bidstream data | 115+ buying signals including hiring, funding, tech adoption, expansion, and job postings |
| Personalized outreach | No outreach capabilities — data only | 3-model AI chain (GPT + Claude + Gemini) generates research-backed personalized messaging |
| ICP refinement | Static filters — you define ICP manually and it never changes | Adaptive ICP that evolves based on which leads reply, convert, and close |
| CRM integration | Exports and syncs to major CRMs | Auto-delivers enriched leads to CRM, Slack, and outreach tools |
| Deduplication | Basic duplicate detection within lists | Cross-campaign deduplication ensures no contact is prospected twice |
| Contract commitment | Annual contracts with auto-renewal; difficult to cancel | Flexible terms, no long-term lock-in |
Where ZoomInfo Falls Short
Pricing starts at $15,000/year for basic plans and can exceed $40,000/year for teams, making it prohibitive for startups and SMBs.
The platform is a static database — you get the same results for the same query whether it is January or December. There is no mechanism for the tool to learn what works for your specific market.
List building is entirely manual. Sales reps spend hours each week building, filtering, and exporting lists that still need enrichment and verification elsewhere.
Intent data relies heavily on Bidstream (third-party cookie tracking), which is becoming less reliable as browsers phase out cookies and privacy regulations tighten.
No outreach capabilities. After you pull a list from ZoomInfo, you still need a separate outreach tool (Outreach, Salesloft, etc.) to actually contact those leads.
Data accuracy degrades rapidly. Job changes, company pivots, and email bounces mean your expensive database has a shelf life measured in months.
Annual contracts with auto-renewal clauses are a common frustration. Teams often pay for a full year of access they do not fully use.
Where Greenway Wins
Greenway costs less than 3% of one SDR's fully loaded salary, compared to ZoomInfo's $15K–$40K+ annual contracts — and Greenway actually does the prospecting work, not just data access.
The learning loop means Greenway gets measurably better over time. Day 1 reply rates of ~5% compound to ~45% by Day 90 because the system learns which accounts, titles, and messaging approaches generate responses.
Greenway is autonomous. It runs daily without any manual list building, filtering, or exporting. Your team wakes up to new qualified leads in their CRM and Slack.
115+ buying signals go far beyond web traffic intent. Greenway detects hiring patterns, funding rounds, technology adoption, geographic expansion, and dozens of other real-world indicators that a prospect is in-market.
Personalization is built in. Greenway uses a 3-model AI chain to generate research-backed messaging for every lead — something ZoomInfo cannot do at all.
No separate outreach tool needed. Greenway handles the full pipeline from identification through personalized messaging delivery.
