How to Build a B2B SaaS Marketing Stack

The order we'd build it in, and the tools we'd reach for at each step.

1

Set the foundation

Pick a CRM and a website platform first. Everything else plugs into these.
CRM: HubSpot's free tier is enough to start.
Website: Webflow for design control, HubSpot CMS for everything-in-one.
Output: Contacts, deals, and website traffic tracked in one place.
2

Capture existing demand

Get in front of people already searching for what you sell.
Google Ads for high-intent search.
Microsoft Ads for the same campaigns at 30 to 40 percent lower CPC.
Hotjar on the pages that matter, to see where visitors drop off.
Output: A working demand capture loop with visibility into friction.
3

Build the organic engine

Once paid is running, start the longer compounding play.
Ahrefs for keyword research and competitor gaps.
Surfer SEO or Clearscope for content briefs and grading.
Publish through your CMS, track rankings back in Ahrefs.
Output: A content pipeline targeting buying-intent keywords.
4

Distribute and nurture

Move people from cold to warm to qualified.
LinkedIn Ads for ABM and content distribution to target accounts.
Meta Ads for retargeting at a fraction of LinkedIn's CPM.
Active Campaign or HubSpot Marketing Hub for nurture sequences.
Output: Warm pipeline you can attribute back to a channel.
5

Add outbound when inbound is steady

Outbound works best as a layer on top, once inbound is producing signal.
Apollo.io for prospecting and sequencing on the free or low tier.
Clay when you need enrichment and AI personalization at scale.
ZoomInfo if you sell to director-plus contacts at enterprise accounts.
Output: An outbound motion that runs alongside inbound.
6

Measure and prune

Stacks bloat fast. Review quarterly and cut what isn't pulling weight.
HubSpot attribution (Professional tier) or Marketo Measure for enterprise.
Hotjar when conversion dips and you need to see why.
Cancel anything that hasn't been opened in 60 days.
Output: A stack that earns its place against pipeline impact.
