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
