AI-Powered B2B Sales Platform
nexuscale.ai
An all-in-one autonomous sales platform that unifies lead generation, AI-powered outreach, and LinkedIn automation. Replaces the need for multiple disconnected tools like Apollo, Clay, and Instantly with one intelligent autopilot.
The Problem
The CEO, a sales professional, was frustrated with the fragmented B2B sales stack. To run effective outbound campaigns, he needed Apollo for leads ($1,188/yr), Clay for enrichment ($1,788/yr), Instantly for sending ($1,068/yr), and more tools for LinkedIn automation. This meant managing 5+ disconnected subscriptions, switching between platforms constantly, and paying over $4,000 per year for a broken workflow. Each tool had its own interface, data silos, and learning curve—making it impossible to work efficiently.
The Solution
I built nexuscale.ai—an all-in-one autonomous sales platform that unifies everything in a single tool. Instead of juggling multiple disconnected subscriptions, businesses get access to a database of 200M+ leads, AI-powered personalization using LinkedIn, Google News, and website data, and multi-channel sending across email and LinkedIn—all in one intelligent autopilot that works 24/7.
🎯 Find Right Buyers
Enables users to find and select leads from a database of 200M+ prospects, scanning millions of live buying signals to surface prospects ready to buy now.
✍️ Hyper-Personalized Content
Uses LinkedIn data, Google News, website information, and real-time signals (funding, hiring, role changes) to write outreach that feels human and personalized.
How It Works
User signs up and enters their website or company information
AI analyzes the information and generates unique pain points, selling points, and personalized messaging
User selects leads from the 200M+ database and adds them to an agent (a series of automated steps)
The autopilot sends personalized emails and follow-ups based on user settings, working 24/7 to book meetings

Challenges & Solutions
The Challenge
Managing a database of 200M+ leads was the biggest technical challenge. Traditional database approaches couldn't handle the scale—queries would slow down, storage costs would skyrocket, and the system would struggle with real-time lookups and updates. We needed a solution that could efficiently store, index, and retrieve millions of records instantly.
Additionally, integrating SMTP for email sending was particularly challenging. Unlike API-based integrations (Gmail, Outlook), SMTP required handling different protocols, managing connection pools, and ensuring reliable delivery across multiple email providers.
How We Overcame It
Strategic Database Indexing & Denormalization
We created comprehensive indexes on frequently queried fields and strategically denormalized the database to reduce join operations. This allowed us to perform lightning-fast lookups even with 200M+ records. By pre-computing and storing commonly accessed data together, we eliminated expensive queries and improved response times by orders of magnitude.
SMTP Integration Architecture
For SMTP, we built a robust connection pooling system that manages multiple email provider connections efficiently. We implemented retry logic, rate limiting, and delivery tracking to ensure reliable email delivery. The system handles different SMTP configurations and adapts to various provider requirements automatically.
LinkedIn Automation Innovation
We developed a sophisticated LinkedIn automation system that handles connection requests, messaging, and engagement while respecting platform limits and maintaining account safety. This required reverse-engineering LinkedIn's behavior patterns and building intelligent rate limiting mechanisms.
Team & Leadership
I led a team of 2 brilliant developers, guiding technical decisions, architecture, and implementation. Together, we built nexuscale from concept to a platform that launched on AppSumo and gained over 1,400 customers. It's been incredible to see how this project evolved from solving my cofounder's frustration with disconnected tools to becoming a unified solution that helps thousands of sales teams work more efficiently.
As CTO and lead developer, I architected the system, built the core infrastructure, and mentored the team through complex technical challenges. The collaboration and growth we achieved together made this one of my most rewarding projects.
