The Revenue Stack Is Evolving Beyond the CRM

Evan Brooks · VP of Revenue Operations·June 5, 2025·7 min read

Five years ago, “the revenue stack” meant the CRM. That’s not true anymore. Modern revenue teams operate on a layered stack where the CRM is one layer of several, and not always the most important one. Understanding the new layers — and where your stack falls short — is a leadership-level concern for any revenue leader who wants to compete.

The five layers of a modern revenue stack

A coherent modern revenue stack has five distinct layers:

Identity layer. Who are your customers and prospects? Sources include CRM, data enrichment providers, intent platforms.

Engagement layer. How are we communicating with them? Email, calls, social, video, content.

Operations layer. How does work flow? Quoting, contracts, approvals, handoffs.

Intelligence layer. What’s working? Pipeline analytics, forecasting, attribution.

Experience layer. What does the buyer see? Proposals, signing experiences, onboarding.

The CRM partially serves layers 1, 2, and parts of 3. It barely serves 4 and doesn’t really serve 5. Companies that rely on the CRM alone are missing layers entirely. (See Why Revenue Teams Need More Than a CRM.)

Why the stack expanded

Three reasons:

  • Buyer expectations rose (they expect signing experiences like Stripe Checkout, not 1990s DocuSign)
  • Sales motions got more complex (multi-touch, multi-stakeholder, multi-channel)
  • Specialized tools emerged for each layer (Gong for calls, Apollo for prospecting, ContractWorks for contracts, etc.)

The CRM tried to expand to cover more layers. The specialized tools won most of the layers. The result is a layered stack instead of one platform.

Where most stacks fall short

In my experience, three layers tend to be under-built:

Operations. Quoting, approvals, and handoffs are usually scattered across tools, spreadsheets, and email. Custom is often the right answer here. (See Why the Future of Revenue Operations Is Custom.)

Intelligence. CRM reporting is rarely sufficient for real forecasting and pipeline analysis. Either a dedicated BI tool or custom analytics fills the gap.

Experience. The buyer-facing parts of the sales process (proposals, signing, onboarding) often get the least design attention. Modern revenue leaders are investing here.

What to do

Map your current stack against the five layers. Identify which layers have tools and which are bare. For the bare layers, decide whether to fill with off-the-shelf or custom.

The companies pulling ahead in B2B sales right now are filling all five layers with intentional choices. The ones still saying “we have a CRM” are operating in 2018 while their competitors moved on.
