B2B Lead Generation SaaS

Client: LeadForge  •  2026-05-10

$500K ARR in 8 months
1,200+ active users
35% MoM growth

LeadForge had a vision for an automated B2B outbound platform but zero technical foundation. They needed a co-founder-level engineering partner to take them from idea to market in under a year.

The Challenge

The founders had deep sales expertise but needed an entire technical stack built from scratch: user authentication, multi-channel outreach automation, analytics, billing, and a CRM integration layer — all while preparing for a seed fundraise.

Our Solution

We became their embedded engineering team for 8 months, building:

  • Full-stack SaaS platform with multi-tenant architecture, team workspaces, and role-based permissions
  • Automated outreach engine supporting LinkedIn, email, and Twitter sequences with AI-personalized messaging
  • Contact enrichment pipeline integrating Apollo, Hunter.io, and Clay for real-time lead data
  • Analytics dashboard with campaign performance metrics, reply rates, and revenue attribution
  • Stripe billing with freemium, starter, and enterprise tiers including usage-based pricing
  • CRM integrations with HubSpot, Salesforce, and Pipedrive via Zapier and native webhooks

Technology Stack

Next.js App Router frontend, Node.js/Express API layer, PostgreSQL with Prisma ORM, Redis job queues (BullMQ), Stripe for billing, and Vercel + Railway for hosting.

Results

  • $500K ARR reached within 8 months of launch
  • 1,200+ active paying users across 40+ countries
  • 35% month-over-month growth sustained for 6 consecutive months
  • Successfully closed a $1.2M seed round with the platform as a core asset
