MarTech Stack Diagram Template (Free PowerPoint Download)

A MarTech stack diagram is a single-page map of every tool your marketing team runs, grouped into layers by the job each one does — data foundation, attract, capture, nurture, create and measure. It turns an invoice list into an architecture you can actually reason about, and it makes overlap, gaps and wasted spend obvious at a glance.

Most teams cannot draw their own stack from memory. That is the problem — you cannot rationalise what you cannot see. This page gives you a free, editable PowerPoint template to map yours in about twenty minutes, plus the six layers to use and how to read the finished picture.

The six layers of a MarTech stack diagram

Group by job to be done, not by vendor. Six layers cover almost every B2B and B2C stack:

How to fill in the template in 20 minutes

1. Export the invoice list (5 min). Pull every marketing subscription from finance. Not what you think you use — what you actually pay for.
2. Drop each tool into a layer (8 min). Duplicate the blank slide and type each tool into the layer whose job it does. A tool that spans two layers goes in the one it does best.
3. Mark the overlaps (4 min). Any layer with three or more tools doing the same job is your consolidation candidate. Colour those boxes.
4. Mark the gaps (3 min). An empty or thin layer is where work is happening by hand — usually Create or Measure.

How to read your finished diagram

Three patterns show up almost every time:

A crowded Attract layer. Marketing tools are easy to buy, so the top of the stack accumulates. Two or three overlapping tools here is normal; five is a budget conversation.

A thin Create layer. Most stacks have a writing tool and nothing else, because the eight steps after the draft (brand voice, images, SEO metadata, schema, publishing, internal links, verification) are done by people. That is the draft-to-published gap, and it is where most of the week goes.

A disconnected Data foundation. If the layers do not read from one source of truth, every report disagrees. Fix this before buying anything else.

Once the picture is drawn, score it. Our MarTech stack audit template puts numbers against each tool, how to build a B2B MarTech stack covers the rebuild sequence, and B2B vs B2C stacks explains why your architecture should differ by model. The full context sits in the complete guide to MarTech stacks.

Frequently asked questions

What is a MarTech stack diagram?

A single-page map of every marketing tool you run, grouped into layers by the job each does: data foundation, attract, capture, nurture, create and measure. It makes overlap, gaps and unused spend visible at a glance.

Is the template really free?

Yes — it is an editable PowerPoint file with no email gate. Three slides: instructions, a blank layered canvas to fill in, and a worked B2B example.

How many layers should a MarTech stack diagram have?

Six covers almost every team: data foundation, attract, capture, nurture, create and measure. Delete any layer you do not run rather than inventing tools to fill it.

How often should I redraw it?

Once a quarter, or before any renewal or new purchase. Stacks grow quietly — a quarterly redraw catches the drift before the invoices do.
