Turnkey AI B2B SaaS that generates personalized client proposals in 60s.
The Closer Node is a sovereign outbound weapon. Tech Stack: Next.js, TailwindCSS, Supabase, Groq API (Llama-3-70b), Vercel. The Pitch: Stop letting your agency or freelance business bleed leads because you take too long to write proposals. AI Client Closer is a fully developed, hyper-fast Micro-SaaS designed to generate world-class, highly personalized client proposals and smart follow-up email sequences in under 60 seconds. How it works: The user inputs a client's website URL or a brief project description. The backend securely connects to the Groq API (running Llama-3-70b at 800+ tokens per second) to instantly generate a tailored, psychologically optimized proposal ready to be sent to the client. Why this is a massive opportunity for the buyer: Zero API Overhead: The app is currently wired to Groq's free tier, meaning your API costs are $0 to run this. Ready to Monetize: The codebase is clean. You can instantly plug in Stripe to charge freelancers $29/month, or use it internally for your own agency to close more deals. Premium UI/UX: Built with modern Next.js and Tailwind, it looks and feels like a Silicon Valley SaaS. The Math: 3,000 users × $29/mo = $1,000,000+ ARR potential in a market of 73M freelancers. What is included in the sale: Full GitHub Codebase transfer. Vercel Hosting & Supabase Database transfer. 1 hour of Zoom handover support to ensure you are up and running.
