LeadPulse Sales Dashboard - Built with Projexlight in 7 days

LeadPulse Sales Dashboard — live at leadpulse.projexlight.com

"We built and shipped a production-ready SaaS product in 7 days — including PRD, code, tests, and deployment — using only Projexlight."

Why We Built LeadPulse

We wanted to prove something that every founder and CTO asks us: "Can Projexlight actually deliver production-ready software at the speed you claim?"

So we decided to dogfood our own platform. We built LeadPulse — a full AI-powered sales intelligence and lead management SaaS — entirely using Projexlight. Not a toy demo. Not a prototype. A real product with real users, real data, and real complexity.

What Is LeadPulse?

LeadPulse is an AI-powered sales intelligence platform that automates the entire B2B prospecting workflow:

Prospecting & Discovery

AI-powered business discovery interviews, prospect search, pipeline management, data validation, and lead prioritization.

Lead Enrichment & Scoring

Profile enrichment, lead scoring with AI signals, sentiment analysis, and sentiment scorecard for every prospect.

Outreach & Messaging

Prospect templates, AI-powered sequences, personalized AI recommendations, and automated follow-ups.

Pipeline & Automation

Full pipeline management, follow-up rules, adaptation rules, AI automation, and deal tracking.

Traditional Timeline vs. Projexlight

What Normally Happens

  • 2–3 weeks for planning and PRD
  • 1–2 weeks for implementation per sprint
  • QA cycle after code is done
  • Total: 6–10 weeks minimum

What Happened with Projexlight

  • PRD generated in under an hour
  • Structured backlog created automatically
  • Code generated sprint-by-sprint with AI tools
  • Tests auto-generated and executed in parallel
  • Deployed to AWS within 7 days

Technical Details

To address the obvious question: "Isn't this easier because it's your own product?" — let's be transparent about what LeadPulse actually involves:

Stack

React + TypeScript frontend, Node.js + Express backend, PostgreSQL database, deployed on AWS

Complexity

Multi-tenant SaaS with authentication, role-based access, real-time dashboards, and AI-powered workflows

Integrations

LinkedIn data enrichment, AI-powered email generation, sentiment analysis, automated prospect scoring

Features

Prospecting, lead enrichment, outreach automation, pipeline management, AI recommendations, analytics dashboards

This is not a landing page or a CRUD app. LeadPulse is a complex, multi-module SaaS product with AI integrations, real-time data processing, and enterprise-grade architecture.

How Projexlight Made This Possible

1. Structured PRD Generation

Instead of spending weeks on planning docs, we described what LeadPulse should do in plain English. Projexlight generated a complete PRD with epics, user stories, acceptance criteria, and BDD test scenarios — in under an hour.

2. Requirements Tied to Tests

Every user story had acceptance criteria. Every acceptance criterion had corresponding BDD scenarios. This means we knew exactly what "done" looked like before a single line of code was written.

3. AI Code Generation with Context

AI coding tools (Cursor, Claude Code) received structured context from Projexlight — not vague prompts. The result: consistent architecture, proper patterns, and code that actually integrates.

4. Automated Validation

283 distinct APIs tested with multiple data variations each — positive, negative, and edge cases — plus end-to-end workflow chain validations. Every change was validated before it shipped. No manual QA bottleneck.

5. Standards Enforcement

Projexlight enforced consistent architecture patterns, API contracts, and coding standards across all sprints. The AI didn't "mutate everything" — it built within defined guardrails.

The Result

7x
Faster delivery vs. previous sprint velocity
100%
API endpoints tested with multi-variant datasets
Live
In production, serving real users on AWS

Why This Matters

Every AI tool claims speed. Projexlight delivers speed with structure.

The LeadPulse case study proves that you can build a complex, multi-module SaaS product in days — without sacrificing testing, architecture, or production readiness.

Founders trust builders who dogfood their own system. We didn't just build a platform that promises fast delivery. We proved it by shipping a real product with it.
