The Lead Generation
Machine
We replaced Clay's 17.3M weekly API hits with a custom system, built entirely in Claude Code by non-developers.
System Architecture
The Tech Stack
Claude Code
$200/mo. Builds and iterates the whole system
GitHub
Version control and cloud storage for all the code
Railway
50 parallel workers running 24/7 for ~$20/mo
Postgres / Convex
Stores every lead, validation, and enrichment
Vercel
Hosts the dashboards the team works in

Vibe-Coded Tools
What We Built
Google Maps Scraper
Pulls local businesses zip code by zip code across 32K+ zip codes. Took 3-4 hours to build.
AI Lead Finder
When data vendors come up empty, AI searches the entire internet for contacts. Gets 95%+ match rate vs 30% from Apollo.
Ad Library Scrapers
Scrapes the Google and LinkedIn ad libraries for companies already spending on growth. Warmer leads by default.
Executive Summary AI
A daily read on every campaign: open rates, reply rates, meetings booked, plus copy analysis and recommendations per ICP.
50M Lead Database
Private catalog of every lead we've ever pulled. It compares data vendor accuracy per ICP so we can tune the enrichment waterfall.
Auto Lead Management
Cleans Instantly workspaces, uploads fresh leads, and keeps clients from running dry. Friday analytics report included.
Before vs After

| Row limits | 50K per table | Unlimited |
| Workspace limits | 12.5M rows total | None |
| Monthly cost at scale | $$$$ (usage-based) | ~$200/mo |

How to Build Your Own
Start with one pain point
Pick the biggest bottleneck in your workflow. For us it was processing speed and row limits.
Build with Claude Code
Describe what you want. No coding knowledge needed. James built the core system in 1 week.
Deploy to Railway
Spin up workers that process 24/7. 50 parallel workers = 272K leads/sec.
Store in Postgres
Save every lead, enrichment, and validation result. Move to Convex when you need real-time.
Visualize on Vercel
Dashboards auto-deploy from GitHub. See campaign performance in real-time.
Expand & iterate
Solve the next pain point. Scrapers, AI enrichment, analytics: one piece at a time.

What It Produced For Clients
Done for you
We'll Run This Machine For You
The same infrastructure behind RB2B, Fyxer, and Directive. We build it, run it, and keep optimizing it. You reach 100% of your TAM every 30-60 days.
Starting at $6,000/mo. If we don't deliver, we work for free.
