At Senko GTM, one of the first things we do with a new client is audit their tech stack - because the tools you choose shape everything about how your outbound operation runs.
What is a GTM Tech Stack?
A GTM tech stack is the collection of software tools your revenue team uses to identify, reach, engage, and close potential customers. It spans every stage of the outbound process - from finding the right companies and contacts, to sending emails, to tracking pipeline.
The Layers of a Modern GTM Stack
Layer 1 - Data and Enrichment
- ICP and list building - LinkedIn Sales Navigator, Apollo, Clay
- Lead enrichment - Clay orchestrating Apollo, Hunter, BuiltWith, Clearbit
- Intent data - Bombora or G2
Layer 2 - Sequencing and Sending
- Smartlead - Strong deliverability, preferred by GTM agencies
- Instantly - High-volume outbound with inbox rotation
- Lemlist - Visual personalisation campaigns
Layer 3 - CRM
- HubSpot - Most popular for growing teams
- Salesforce - Enterprise standard
- Pipedrive - Clean, sales-focused interface
Layer 4 - AI and Automation
- Clay with Claygent for AI-driven research and personalisation
- LLM integrations (GPT-4o, Claude) for writing personalised openers
- Zapier or Make for connecting tools without native integrations
Layer 5 - Analytics and Reporting
Combine sequencing tool analytics with CRM pipeline reporting for full visibility.
Lean Stack vs Full GTM Stack
Avoiding Tool Bloat
A tight, well-integrated stack of five tools outperforms a sprawling stack of fifteen that nobody fully understands. Start lean. Review quarterly. Cut anything not pulling its weight.
At Senko GTM, we help teams build GTM stacks right-sized for their stage - not sold on complexity they do not need.
