No More "Who Approved This Vendor?"
Marketing buys tools. IT doesn't know. Finance gets the invoice. Nobody tracked the decision. Governance turns your stack from a political minefield into a structured, auditable process — with clear ownership, approvals, and accountability across every department.
The governance gap
Most organizations have governance for code (Git, pull requests), for infrastructure (Terraform, change management), and for data (access controls, lineage). But Martech stacks — often representing $100K-$1M+ in annual spend — have zero governance. Anyone can buy a tool, nobody tracks dependencies, and changes happen without review.
Stack Builder brings the same structured governance to your Martech stack: propose changes, review impact, approve or reject, and maintain a full audit trail. No more shadow IT, no more surprise vendor changes, no more "who approved this?"
A structured workflow for stack changes
Every change follows the same four-step process — from proposal to implementation.
Propose
Team members submit formal proposals to add, remove, or replace tools. Each proposal includes rationale, impact assessment, and cost implications.
Review
Stakeholders review the proposal with full context — see how the change affects data flows, integrations, and the overall architecture. Comments and discussions happen in-line.
Approve
Designated approvers accept, reject, or request modifications. Multiple approval gates for high-impact changes. Every decision is documented.
Implement
Approved changes are tracked with task management. The diagram updates to reflect the new state. Full audit trail of what changed, when, and why.
Governance features built for Martech teams
Everything you need to manage stack changes with structure, transparency, and accountability.
Proposals & Approval Workflows
Every stack change goes through a structured review. Submit proposals with rationale, impact analysis, and cost data. Reviewers see the full architectural context before approving.
- Structured change requests
- Impact analysis before changes
- Multi-stakeholder approval
- Full audit trail
Department Ownership
Assign every tool to a responsible department and owner. The Ownership lens shows who manages what across the entire stack. No more orphaned tools with unclear accountability.
- Clear tool ownership
- Department-level accountability
- Ownership lens view
- No more orphaned tools
Role-Based Access Control
Admin, Editor, and Viewer roles control who can modify your stack architecture. Editors can propose changes; Admins can approve them. Viewers get read-only access for visibility.
- Three role levels (Admin, Editor, Viewer)
- Propose vs. approve separation
- Read-only access for stakeholders
- Flexible permission model
Comments & @Mentions
Discuss changes in context with threaded conversations. @Mention team members to bring them into the discussion. Every comment is linked to the proposal and preserved in the audit trail.
- Threaded discussions
- @Mention notifications
- In-context conversations
- Comments preserved in audit trail
The method
Establish governance by hand
Governance fails when it is written as policy and never as a check someone runs. This procedure produces a small number of checks with names attached. A day to write, an hour a month to run.
-
List every tool that touches personal data
Not every tool — the ones holding or receiving anything identifying. Be generous about what counts: an email address in a support tool is personal data.
-
Trace consent from collection to use
For each of those tools, write where the consent came from and what it permits. Where you cannot complete the sentence, you have found a gap — and it is better found by you than by a regulator.
-
Name an owner per tool, not per policy
One person per tool who is accountable for its data. Policies without per-tool ownership are how a stack ends up compliant on paper and not in practice.
-
Write the three checks you will actually run
Three that get run beat twenty that do not. Good candidates: new tools added since last review, consent-string coverage on the highest-traffic path, and access for people who have left.
-
Put the review in the calendar with the owners invited
An uncalendared review is a document. Monthly or quarterly; the cadence matters less than it existing.
European retailer, 19 tools, 11 touching personal data.
| Tools touching personal data | 11 |
|---|---|
| Consent path fully traceable | 6 / 11 |
| Tools with a named owner | 4 / 11 |
| Added since last review | 3 |
| Retained access, departed staff | 2 tools |
Reading it: Five untraceable consent paths is the compliance headline, but four named owners out of eleven is the cause. Ownership is the fix that makes the other numbers move.
The shortcut: The Consent and Data Classification lenses trace step 2 across the diagram, so the gaps surface as you build rather than during an audit.
