LegalLens was a classic PLG tool struggling with a complex UI. By replacing their 20-step document builder with a single 'Upload & Analyze' Agent, they removed cognitive friction entirely. Implementation took 3 months, but reduced churn by 40% and doubled LTV.
Key Takeaways
- Users don't want 'features'; they want 'relief'.
- Replacing UI with Agents is the ultimate simplification.
- The 'Empty State' is the biggest enemy of retention.
- You can charge premium prices for 'Done-For-You' outcomes.
LegalLens (fictional name for a real client) had a problem common to many vertical SaaS companies. Their product was powerful, but it was intimidating. It was a contract lifecycle management (CLM) tool.
New users would sign up (Product-Led Growth), stare at the dashboard of 50 different contract templates, get overwhelmed, and leave. Their activation rate was 18%. Churn was 5% monthly.
They thought they needed 'better tutorials'. We told them they needed an Agent.
The Before: The 'Wall of Buttons'
The onboarding flow relied on the user taking initiative:
- Sign Up.
- Choose 'NDA' from a dropdown.
- Fill out 20 form fields (Counterparty, Date, Jurisdiction...).
- Download PDF.
Users hated the form. It felt like work. They were paying $30/month to do data entry.
The Transformation: Enter the 'Paralegal Agent'
We gutted the UI. We removed the template breakdown. We replaced the dashboard with a single massive drag-and-drop zone.
The New Flow (ALG):
- User drags a messy Word doc or PDF of *any* contract.
- Agent scans it (using OCR + LLM).
- Agent identifies missing clauses: "This NDA is missing a Non-Solicit clause. Want me to add it?"
- User clicks 'Yes'.
- Agent rewrites the file and emails it to the counterparty.
The Metrics: 40% Activation Jump
The results were immediate. By removing the 'Cognitive Load' of the form, users felt relieved.
| Metric | PLG (Forms) | ALG (Agent) |
|---|---|---|
| Time to Value | 12 Minutes | 45 Seconds |
| Activation Rate | 18% | 58% |
| Support Tickets | High ("How do I save?") | Low ("Thanks!") |
Under the Hood
We didn't build a spaceship. We used off-the-shelf tools:
- OCR: Vercel AI SDK to stream the text extraction.
- Logic: GPT-4o for the legal reasoning.
- Memory: Pinecone to store the user's previously accepted clauses (so the agent learns their style).
LegalLens stopped trying to teach their users to be lawyers. Instead, they built an Agent that acted like a lawyer. That shift—from tool to service—is the core promise of Agent-Led Growth.
