The 2026 RevOps Data Stack: Architecture and Tool Selection

The RevOps data stack has changed a lot. What used to be “buy ZoomInfo, connect to Salesforce” is now an ecosystem of specialized tools, orchestration layers, and real-time workflows.

This guide maps out the modern RevOps data stack and how to build one.

Stack by Company Stage

Startup ($0-5M ARR)

Budget: $500-2,000/month

CRM:
└── HubSpot Free/Starter

Data Sources:
└── Apollo (primary) — $99/user/mo

Enrichment:
└── Apollo native enrichment

Email Verification:
└── NeverBounce (pay-as-you-go)

Deduplication:
└── HubSpot native tools

Total: ~$100-200/month for a small team

Why this works:

Apollo provides database + sequences in one
HubSpot handles CRM without cost
Minimal integration complexity
Scales with you

Growth Stage ($5-25M ARR)

Budget: $3,000-10,000/month

CRM:
└── Salesforce Professional or HubSpot Professional

Component Deep Dives

CRM: The Foundation

Your CRM is the system of record. Everything flows through it.

Salesforce:

Most customizable
Best for complex sales processes
Requires admin expertise
Higher cost

HubSpot:

Easier to use
Better marketing integration
Growing enterprise features
Lower TCO for many

Key CRM requirements for data operations:

API access (for integrations)
Custom fields (for enrichment data)
Workflow automation (for triggers)
Duplicate management (native or add-on)

Data Sources: Coverage is King

No single provider has complete coverage. Plan for multiple sources.

Provider Comparison (2026):

Provider    | Contacts | Direct Dials | EU Coverage | Price
─────────────────────────────────────────────────────────────
ZoomInfo    | 321M+    | Excellent    | Good        | $$$$
Apollo      | 270M+    | Good         | Fair        | $$
Cognism     | 200M+    | Excellent    | Excellent   | $$$
Lusha       | 150M+    | Excellent    | Good        | $$
Clearbit    | 200M+    | N/A          | Good        | $$$

Recommendation:
- US-focused: ZoomInfo or Apollo
- EU-focused: Cognism + Apollo
- Phone-focused: Cognism + Lusha
- Budget-focused: Apollo alone

See individual guides:

Orchestration: Clay as the Hub

Clay has become the de facto orchestration layer:

Clay's Role:

1. Waterfall Enrichment
   - Connect to 100+ data sources
   - Route based on coverage and cost
   - Fill gaps automatically

2. Data Transformation
   - Standardize formats
   - Calculate scores
   - Generate AI insights

3. CRM Integration
   - Push enriched data to Salesforce/HubSpot
   - Trigger on CRM events
   - Bi-directional sync

4. Custom Workflows
   - No-code automation
   - Complex branching logic
   - Multi-step processes

Intent Data: Timing is Everything

Intent data identifies accounts researching your category:

Intent Provider Comparison:

Bombora:
- Largest B2B intent co-op
- Topic-based scoring
- Best for: Account prioritization

G2:
- G2 Crowd buyer intent
- Category-specific
- Best for: Competitor intelligence

6sense:
- AI-powered intent platform
- Full ABM capabilities
- Best for: Enterprise ABM

TrustRadius:
- Review-based intent
- High quality signals
- Best for: Competitive situations

Data Quality: Prevention and Cure

Quality tools fall into two categories:

Prevention (Real-time):

Salesforce duplicate rules
HubSpot deduplication
RingLead (real-time)

Cure (Batch):

DemandTools (Salesforce)
Cloudingo (Salesforce)
Insycle (HubSpot)

Verification:

NeverBounce (email)
ZeroBounce (email)
Phone verification services

Integration Patterns

Pattern 1: Hub and Spoke

Clay (or similar) as central hub:

            ┌─────────┐
            │  CRM    │
            └────▲────┘
                 │
     ┌───────────┴───────────┐
     │         Clay          │
     └───────────┬───────────┘
        ┌────────┼────────┐
        ▼        ▼        ▼
   ┌────────┐┌────────┐┌────────┐
   │ZoomInfo││ Apollo ││Cognism │
   └────────┘└────────┘└────────┘

Pros:

Centralized control
Easy to modify workflow
Clear data lineage

Cons:

Single point of failure
Adds latency
Clay dependency

Pattern 2: Direct Integration

Each tool connects directly to CRM:

   ┌────────┐     ┌────────┐     ┌────────┐
   │ZoomInfo│     │ Apollo │     │Cognism │
   └───┬────┘     └───┬────┘     └───┬────┘
       │              │              │
       ▼              ▼              ▼
   ┌─────────────────────────────────────┐
   │               CRM                    │
   └─────────────────────────────────────┘

Pros:

Simpler architecture
Lower latency
Fewer dependencies

Cons:

Duplicate management harder
No waterfall capability
Multiple integrations to manage

Pattern 3: Event-Driven

Real-time events trigger enrichment:

CRM Event → Event Bus → Enrichment → CRM Update

Technologies:
- Salesforce Platform Events
- HubSpot Workflows + Webhooks
- Kafka/SQS for scale

See Event-Triggered Enrichment for details.

Build vs Buy Decisions

Build When:

You have unique data needs
You need deep customization
You have engineering resources
Volume justifies investment

Buy When:

Standard use cases
Limited engineering
Need to move fast
TCO is lower than build

Hybrid Approach:

Buy:
- Data sources (ZoomInfo, Apollo)
- CRM (Salesforce, HubSpot)
- Basic enrichment

Build:
- Custom scoring models
- Unique workflow logic
- Proprietary data processing

Orchestrate:
- Clay for no-code workflows
- Custom code for complex logic

Common Mistakes

Mistake 1: Too Many Tools, Too Fast

Wrong:
Week 1: Buy ZoomInfo, Apollo, Cognism, Lusha, Clay, Bombora...

Right:
Month 1: One primary source + CRM
Month 3: Add orchestration
Month 5: Add secondary sources
Month 7: Add intent

Mistake 2: No Data Quality Foundation

Wrong:
Focus on adding more data, ignore duplicates and decay

Right:
Implement quality tools BEFORE adding more data sources
Clean existing data BEFORE enriching

Mistake 3: Over-Automating Early

Wrong:
Build complex automated workflows immediately

Right:
Start with manual processes
Learn what works
Then automate

Mistake 4: Ignoring Data Decay

Wrong:
"We enriched everything last year, we're good"

Right:
[70% of data decays annually](/blog/b2b-data-decay-problem)
Continuous enrichment is required
Budget for ongoing refresh
