Start with a proven stack template

Don't stare at a blank spreadsheet. This template organizes your marketing technology by layer — CRM, CMS, tracking, analytics, ads, and automation — with common defaults for HubSpot, GA4, GTM, and more. Open it free, customize for your team, and see where your data might be breaking down.

Seven layers every stack needs

This marketing tech stack template reflects what we audit on every client engagement. Each layer supports tool notes and monthly cost — so you get a real inventory, not just a logo slide. When a layer is empty or tools don't connect, that's usually where your data breaks.

Layer Category Example tools
1 CRM / source of truth HubSpot, Salesforce, Pipedrive
2 Website / CMS WordPress, HubSpot CMS, Webflow
3 Tracking / data collection GTM, Segment, RudderStack, GA4
4 Analytics & reporting GA4, Data Studio, PostHog, Power BI
5 Marketing automation HubSpot, Customer.io, Marketo
6 Digital ads Google Ads, Meta Ads, LinkedIn Ads
7 SEO, social, integrations Search Console, Hootsuite, Zapier
