Executive Summary
For high-growth B2B SaaS companies, sorting through thousands of raw trial registrations slows down sales outreach and lowers conversion rates. This case study details how GInfomedia designed and deployed an AI-driven Lead Qualification System for a high-volume B2B software provider. By combining profile data enrichment with conversation qualification flows, the solution automated lead scoring.
Implemented over a 10-week schedule, the lead qualification system achieved a 3x increase in qualified B2B lead conversions, reduced sales contact latency by 50%, raised sales team productivity by 45%, and reached project payback in 3.3 months.
Client Background
The client is a fast-growing B2B enterprise SaaS company providing human resource management (HRMS) platforms to businesses across India and APAC. They generate over 6,000 trial signups monthly through digital ad campaigns and whitepaper downloads.
With a high volume of raw registrations, the company's sales team spent up to 60% of their time calling low-intent, junk leads (e.g. students or tiny businesses), while high-intent enterprise buyers went uncalled for hours.
Business Challenges
Before implementing the AI lead qualification system, the SaaS company faced critical sales bottlenecks:
- Junk Lead Congestion: Sales representatives wasted hours manually calling low-intent registrants, leading to team burnout.
- Delayed Enterprise Contact: High-value enterprise prospects sat in unstructured queues, increasing contact delay times.
- Incomplete Profiles: Signups lacked critical qualification details (e.g. employee count or CRM usage), requiring manual screening calls.
- Low Sales Conversion: Sales win rates dropped to 2.1% due to delayed follow-ups and uncoordinated outreach.
Objectives
GInfomedia collaborated with the company's marketing and sales leadership to set key objectives:
- Filter Junk Registrations: Automatically qualify and score inbound signups before assigning them to sales reps.
- Accelerate Response Times: Engage high-intent enterprise prospects within 5 minutes of signup.
- Enrich Profiles Automatically: Gather company size, revenue, and tech stack details via data enrichment APIs.
- Unify Sales Data: Sync lead qualification scores, transcripts, and enriched profiles directly with Salesforce CRM.
Solution Architecture
GInfomedia built an API-driven lead qualification and scoring pipeline. It connects signup portals, enrichment APIs, and enterprise CRMs:
1. User Signup & Ingestion
Prospects register on the SaaS trial portal, triggering an instant webhook sent to our Node.js middleware.
2. Clearbit Profile Enrichment
The middleware queries the Clearbit API to fetch company size, annual revenue, industry, and headquarter details.
3. AI Intent Qualification
If details are missing, a Dialogflow chatbot engages the user on the signup page to collect budget and timeline parameters.
4. Salesforce Sync & Alert
Qualified leads are scored (1-100) and pushed to Salesforce CRM, triggering a Slack alert for the assigned enterprise sales rep.
Technology Stack
Data enrichment platform fetching corporate employee counts, revenues, and industry sectors.
State-machine conversational bot qualification engine managing user interactions on the web portal.
Core customer relationship database ingesting validated lead parameters, scores, and transcribing logs.
Express API backend routing webhook calls, running scoring formulas, and managing Redis caches.
In-memory database storing session details, token authentications, and temporary customer parameters.
Alert API notifying sales teams immediately when a high-intent enterprise lead registers.
Development Process
- CRM Scoping & Audit: Analyzed the B2B qualification criteria, sales field parameters, and lead assignment rules.
- Data Integration Setup: Programmed the Node.js middleware to query Clearbit APIs using the customer's email domain.
- Qualification Bot Configuration: Built Dialogflow CX routes to check buyer timelines and B2B requirements.
- Lead Scoring Algorithm Build: Written qualification scoring formulas based on firmographic and conversational parameters.
- System Dry Run & UAT: Processed 1,500 historical signups, verifying profile enrichment accuracy to 96%.
- Production Launch: Switched active trial signup forms to the API qualification gateway.
AI Models & Integrations
The system uses the **Clearbit Enrichment API** to automatically parse incoming email domains. When a user registers with a corporate address (e.g. name@company.com), the API fetches firmographic data (including company size, funding round, country, and technology stack) in under 800ms, enriching the user profile automatically.
For conversational qualification, we integrated **Dialogflow CX** as an interactive form assistant on the pricing page. If the enrichment data indicates a company size of over 100 employees but lacks budget details, the bot prompts the user (e.g. "To suggest the right enterprise tier, how many active users do you expect?"). The parsed answers are scored (1-100) and synced with Salesforce.
Our middleware automatically filters out public email domains (Gmail, Yahoo) and prompts users to register with their corporate email to unlock free enterprise trials, reducing junk signups by 50%.

Results & Metrics
ROI Analysis
The financial returns of the project exceeded the developer's original forecasts. Here is a detailed breakdown of the cost-benefit analysis over the first 6 months of operation:
- Reduced Sales Triage Overhead: Automating profile pre-screening and qualification freed up sales reps, saving **₹4.8 Lakhs monthly** in manual screening costs.
- Higher Deal Values: Fast routing allowed sales teams to close enterprise contracts before competitors responded, increasing deal values by **₹3.6 Lakhs monthly**.
- Payback Period: The total system development cost was recovered in **3.3 months**, with compounding returns thereafter.

Frequently Asked Questions
How accurate is Clearbit data for Indian corporate domains?
Clearbit maintains high-fidelity directories for corporate domains globally. If a domain is not found, our middleware falls back to Dialogflow questions to collect details manually.
Can the lead qualification score be customized as sales goals change?
Yes. The scoring logic is managed in a configuration file within the Node.js backend, allowing administrators to modify criteria weights (e.g. employee count or country) instantly.
How is customer data privacy maintained during profile enrichment?
All data transit is encrypted via TLS 1.3. Enriched details are stored securely in Salesforce, and data transfers comply with Indian digital personal privacy regulations.
What happens if a qualified user registers out of business hours?
The system qualifying and scoring lead runs 24/7. High-scoring leads trigger SMS alerts to the assigned rep immediately, and the lead is marked for priority callback the next morning.
