leadtrain.app
A lead generation and sales automation platform that helps B2B companies identify, qualify, and engage prospective customers. Integrates with LinkedIn, email providers, and CRM systems to create automated outreach sequences with built-in analytics and A/B testing.
The Challenge
LeadTrain's founders identified a gap in the B2B sales market: sales teams spent more time on manual prospecting and repetitive outreach than on actual selling. Existing tools addressed parts of the problem in isolation, but no single platform combined prospect identification, multi-channel outreach automation, and performance analytics into a unified workflow.
The platform needed to integrate reliably with LinkedIn's frequently changing interface, support multi-step email sequences with personalization, connect to major CRM systems, and provide meaningful A/B testing capabilities, all while remaining intuitive enough for sales representatives without technical training.
Our Approach
We built the platform on Next.js for a fast, SEO-friendly frontend with server-side rendering, backed by a Node.js API layer that orchestrates outreach sequences across LinkedIn and email channels. Puppeteer handles browser automation for LinkedIn interactions with human-like timing patterns and session management.
The outreach engine runs on a distributed job queue powered by Redis, processing thousands of personalized messages daily. PostgreSQL stores prospect data, sequence configurations, and analytics events with efficient indexing for real-time reporting dashboards.
The Solution
Multi-Channel Outreach Engine
Automated sequences that combine LinkedIn connection requests, profile visits, and messages with email follow-ups. Human-like timing patterns and session management ensure reliable delivery without account restrictions.
Prospect Intelligence Dashboard
A unified view of all prospects across the pipeline with enrichment data, engagement history, and lead scoring. Integrates bidirectionally with Salesforce, HubSpot, Pipedrive, and other popular CRMs.
A/B Testing & Analytics
Built-in split testing for message templates, subject lines, and sequence timing. Real-time analytics track open rates, reply rates, and conversion metrics with statistical significance indicators.

LeadTrain is now used by over 3,200 sales teams worldwide. Customers report reply rates 47% higher than manual outreach and an average 12x return on investment. The platform processes over 100,000 automated outreach actions daily and has become a core part of B2B sales workflows across industries.
