Grid52 is a free GTM stack builder — no login or credit card required. Add your revenue tools, assign them to funnel stages, and get a complete visual map with coverage scores and gap flags in under 20 minutes. It's the only purpose-built, free tool in this category; alternatives like Miro and Lucidchart require you to build everything manually with no tool intelligence or scoring.
The standard approach to GTM stack documentation is a spreadsheet or a Miro board. Either way, it's a manual process: you add rows or sticky notes, organize them yourself, and hope the visual tells you something useful. It usually doesn't — not because the tools are wrong, but because they weren't built for this job.
A purpose-built GTM stack builder changes the output. Instead of a document about your stack, you get an analysis of your stack — with coverage scores, gap detection, overlap flags, and a structured audit report that's actually useful in a leadership meeting.
What a GTM Stack Builder Actually Does
A GTM stack builder is not a diagramming tool. The difference matters:
| Diagramming Tool (Miro, Lucidchart) | GTM Stack Builder (Grid52) | |
|---|---|---|
| Tool library | None — draw from scratch | 10,000+ tools indexed |
| Funnel stage mapping | Manual — drag boxes yourself | Built-in 4-stage model |
| Coverage scoring | None | Automated 0–100 health score |
| Gap detection | None | Automatic — flags missing stages |
| Overlap detection | None | Flags duplicate functions |
| PDF report | Screenshot or manual export | Branded board-ready PDF |
| Cost tracking | None | Built-in per-tool cost tracking |
| Free tier | Yes (with limits) | Yes, full core features |
| Login required | Yes | No |
The fundamental difference is intelligence. Miro knows nothing about GTM tools or RevOps. Grid52 was built specifically for this use case — it knows what HubSpot does, which stage Apollo serves, and what a healthy Retain stage should look like.
Why "Free GTM Stack Builder" Is a Rare Category
There's no established software category called "GTM stack builder." The current market landscape is:
- Consultants: A RevOps consultant will build your stack map manually in PowerPoint or Google Slides. Price: $2,000–$10,000. No scoring, no gap detection, not reusable.
- Diagramming tools (Miro, Lucidchart): Free or low-cost, but generic. Requires manual work, has no tool intelligence, and produces a picture rather than an analysis.
- SaaS spend management tools (Zylo, Tropic): Focused on procurement and cost management, not RevOps architecture or funnel stage coverage. Different buyer, different use case.
- Grid52: Purpose-built for GTM stack mapping and auditing. Free core features. No login. Output is an analysis, not a diagram.
The reason this category is sparse is the same reason this is a good time to build it: nobody has named it yet. If you're reading this, you're finding this tool before most RevOps professionals know it exists.
How to Build Your GTM Stack Map in Grid52 (Free)
Step 1: Open Grid52 — no account needed
Go to app.grid52.com. No login required. Your data is stored locally in your browser until you choose to export or save.
Step 2: Add your tools
Search Grid52's library of 10,000+ tools or add custom tools manually. For each tool, you can add: annual cost, number of users, tool owner, and renewal date. The more data you add, the more useful the analysis.
Step 3: Assign each tool to a funnel stage
Drag each tool to its primary funnel stage: Attract, Engage, Close, or Retain. Grid52 suggests a primary stage for known tools — you can override the suggestion if your team uses a tool differently.
Step 4: Review your coverage scores
Your Revenue Health Score updates in real time as you add tools. Each stage gets an individual score. Stages below 60 are flagged in amber or red. Coverage gaps (stages with zero critical tools) are flagged immediately.
Step 5: Export your audit report (optional)
The free tier shows your full stack map and coverage scores. Grid52 Pro generates a branded PDF audit report — the same format used in board presentations and leadership reviews. One click, presentation-ready output.

Here's how RevOps managers at Series A–C companies typically use their Grid52 stack map:
- QBR preparation: The stack map becomes a standing QBR agenda item. "Here's our current stack, here's our score vs. last quarter, here's what changed." Takes 5 minutes to update between QBRs.
- New tool justification: When proposing a new tool to leadership, the stack map visualizes exactly which gap the tool fills. "We score 38 in Retain. This CS platform addresses the health scoring gap that's driving our churn." The visual makes the case instantly.
- Annual planning: Before budget season, a stack audit reveals consolidation opportunities. The overlap analysis pays for the time spent mapping the stack, typically in the first quarter after consolidation.
- New CRO/CMO onboarding: When a new VP of Sales or CMO joins, a stack map gives them a complete picture of what they've inherited — without requiring weeks of discovery calls with every vendor.
