|

|
Company Profile:
|
|
{$profile_details}
|
|
|
|
Instructions:
|
|
1. The diagram should visualize the ideal GTM workflow from customer acquisition to retention/upselling.
|
|
2. The output MUST be a valid Mermaid.js graph, starting with 'graph TD;'.
|
|
3. Use the format: A[\"Step 1\"] --> B[\"Step 2\"] --> C[\"Step 3\"];
|
|
4. **Crucially, node text MUST be enclosed in double quotes**, like A[\"This is a node\"];
|
|
5. The steps should be logical and tailored to the company's profile (e.g., a product-led motion should have steps like 'Free Tier Signup', while an enterprise motion should have 'SDR Touchpoint').
|
|
6. Make the flow concise, with 5 to 7 key steps.
|
|
7. Do not include any explanation, just the Mermaid.js code.
|
|
|
|
Example:
|
|
graph TD;
|
|
A[\"Lead Gen via Social Media\"] --> B[\"Free Tier Signup (Product-Led)\"];
|
|
B --> C[\"Auto-Onboarding Email\"];
|
|
C --> D[\"SDR Touchpoint\"];
|
|
D --> E[\"Upsell via Partner Integration\"];";
