For Martech Managers

Your Stack Knowledge Shouldn't Live in One Person's Head

When the CTO asks "what would break if we cut Segment?" — you need a clear answer, not a 30-minute explanation. Build a living architecture that everyone from IT to finance can understand, question, and trust.

Problems you know too well

Managing a growing Martech stack means fighting the same battles over and over. Here's how Stack Builder fixes them.

Stack sprawl with no single view

Your stack has grown to 20, 40, 80+ tools and there's no single place to see how they all connect. Stakeholders ask 'what tools do we use?' and you're digging through spreadsheets.

How Stack Builder solves this

Build your complete stack visually with 460+ pre-built vendor nodes. See every tool, every connection, every data flow in one interactive diagram.

Can't quantify stack health

You know something's off -- redundant tools, poor integrations, data silos -- but you can't put a number on it. Budget conversations become opinion battles.

How Stack Builder solves this

The Stack Evaluation grades your architecture A-F on duplicated capability and puts a number on what it costs. Walk into budget meetings with data, not opinions.

Hard to get buy-in for changes

You want to consolidate tools, but leadership needs to see the impact. PowerPoint diagrams don't convey the complexity.

How Stack Builder solves this

Share a live link, switch lenses to show cost and data flow, and use the evaluation's overlaps and priced duplication to build your case.

The File menu open on Export: PNG, SVG, JSON and CSV

No visibility into data flows

GDPR audit coming and you can't trace where customer data goes across your 50-tool stack.

How Stack Builder solves this

Trace lets you pick any node and see its upstream sources and downstream destinations. The Consent and PII Data lenses show which tools handle personal data and how.

Trace data flow from Twilio Segment: the tools in its path highlighted, 2 upstream and 4 downstream, and the rest dimmed

Key features for Martech managers

How it works

Go from scattered spreadsheets to a living architecture diagram in three steps.

Build your stack

Drag vendors from our 460+ library onto the canvas. Connect them to show data flows.

Evaluate

Open the Evaluate tab for an A-F grade, the overlapping tools and what the overlap costs.

Share with stakeholders

Export presentation-ready diagrams or share interactive links with your team.

A day in the life with Stack Builder

See how Martech managers use Stack Builder to turn complexity into clarity.

9:00 AM -- CMO asks about stack redundancies

Open your stack diagram, run the evaluation, and share the grade and the two overlapping tools it names in the analytics layer.

11:00 AM -- Legal needs a data flow audit

Switch to the PII Data lens and use Trace to show where personal data travels. Run the privacy audit (Pro) and export it as a PDF for the compliance team.

2:00 PM -- Budget review for new CDP

Use the Cost lens to show current spend, then duplicate the diagram, model the proposed architecture, and open Compare Stacks to see the two side by side. Grade both so leadership can compare.

Frequently Asked Questions

How many vendors can I add?

As many as your stack needs. Our library has vendor nodes for 460+ vendors, and you can create custom nodes for internal tools. Cloud saves are limited by plan: 3 on Free, 20 on Pro, unlimited on Consultant, Agency, Team and Enterprise.

Can I share diagrams with stakeholders who don't have an account?

Yes. Create a read-only share link from the Share menu; on paid plans you can add a password or an expiry date, and embed the stack in Confluence or Notion. You can also export the diagram as PNG or SVG for presentations.

How accurate is the AI evaluation?

The grade is not an AI opinion. It is computed from where your tools duplicate each other, using a capability record where most entries cite a source, and priced from the costs you enter. The AI writes the summary around those numbers. Treat it as a starting point for the conversation, not a final verdict.

What if my vendor isn't in the library?

You can create custom nodes for any tool. You can also request vendors be added to our library.

Can I track costs in Stack Builder?

Yes. Enter a cost on each tool; the Cost lens (Pro) colours the diagram by spend. The Stack Costs panel (Consultant, Agency, Team and Enterprise) adds a cost table, renewal dates, spend by department and a forecast.

Is my stack data secure?

All data is encrypted in transit and at rest. It is stored with Supabase, our database provider, and the database keeps each workspace’s data apart from the others. Your diagrams are private by default.
