Accelerating Enterprise Lead Velocity
Sales conversion rates decrease by 391% when lead response times exceed 10 minutes. By deploying a serverless AI lead qualification webhook, incoming inquiries are analyzed, scored for commercial intent, and routed to the correct account executive in under 5 seconds.

TypeScript Server Endpoint Implementation
```typescript
import express from 'express';
import { GoogleGenAI, Type } from '@google/genai';
const router = express.Router();
const ai = new GoogleGenAI({ apiKey: process.env.GEMINI_API_KEY });
router.post('/api/lead', async (req, res) => {
const { name, email, company, teamSize, projectDescription } = req.body;
const response = await ai.models.generateContent({
model: 'gemini-2.5-flash',
contents: 'Analyze this inbound B2B sales lead and output structured JSON: Company: ' + company + ', Team Size: ' + teamSize + ', Notes: ' + projectDescription,
config: {
responseMimeType: 'application/json',
responseSchema: {
type: Type.OBJECT,
properties: {
score: { type: Type.INTEGER, description: 'Score from 0-100' },
tier: { type: Type.STRING, enum: ['ENTERPRISE', 'GROWTH', 'SELF_SERVE'] },
reasoning: { type: Type.STRING }
},
required: ['score', 'tier', 'reasoning']
}
}
});
res.json({ success: true, analysis: JSON.parse(response.text) });
});
```
Operational Checklist
[x] Deploy server-side proxy route to keep `GEMINI_API_KEY` secure
[x] Enforce structured JSON schemas on model responses to ensure reliable CRM webhook parsing
[x] Integrate Slack notifications for leads with intent scores >= 80
