🚀 About 1man.ai

We’re building a platform where solopreneurs can launch and monetize AI-powered tools and virtual agents. Think: AI customer service agents, sales assistants, marketing automators, and back-office bots—all deployable with no overhead.

We handle sales, marketing, and distribution—you focus on shipping clean, useful AI-driven software.

🧩 What You’ll Be Building

You’ll be the hands-on technical cofounder, building tools that businesses can plug into their workflows. Expect to work on:

• 🧠 LLM-powered agents: Using OpenAI, Anthropic, or open-source models
• ⚙️ LangChain / RAG pipelines: Connect LLMs to vector databases (Pinecone, Weaviate) and private data
• 🌐 Next.js / Vercel frontends: Fast, reactive UIs for end users or dashboards
• 🧬 APIs + Automations: Build REST or GraphQL APIs, connect tools like Slack, Gmail, Notion, Stripe, etc.
• 💾 Data infra: Use Supabase, Firebase, or Postgres to store user input, chat history, usage analytics

Example ideas you might ship:

• AI-powered onboarding flows for SaaS
• GPT-driven helpdesk agents trained on company docs
• Lead gen microsites that qualify visitors via LLM
• Notion → PDF automation via AI templating

🛠 Your Toolbox (or ours – up to you)

You should be comfortable working with some or all of:

• Python / TypeScript — LangChain, FastAPI, or Node backend
• React / Next.js / Tailwind — frontend dashboards, UIs, or landing pages
• Vector databases — Pinecone, Weaviate, or Chroma
• LLMs — OpenAI GPT-4, Claude, open-source (Llama, Mistral, etc.)
• Tooling — Supabase, Make.com, Vercel, Docker (nice to have), Stripe integration

🧠 Who You Are

• A technical solopreneur or indie hacker with real shipped projects
• You’ve built products or automations with GPT or similar
• You understand backend and frontend architecture for SaaS
• You enjoy working autonomously, but you’re open to collaboration when needed
• You want to build fast, launch fast, and iterate based on user needs

🎁 What You’ll Get

• Revenue-share or equity per tool shipped and monetized
• Access to real client demand and discovery channels
• No BS: we manage the overhead (marketing, support, legal, billing)
• A fast, product-focused team that believes in launching weekly, not yearly
