What Inspired Us
I'm Prince from Nigeria. My teammate Shaila from Bangladesh and I built NegotiatorX because we saw people around us losing money every day — simply because they didn't know how to ask for better.
My mom once paid $2,500 for rent. She was a good tenant, never missed a payment. But when renewal came, she accepted the increase without asking. She told me: "I didn't want to seem difficult."
That broke my heart. $3,600 a year — gone. Just because she didn't know how to negotiate.
I realized this isn't just my mom. 70% of people never negotiate their salary. Renters overpay by hundreds every month. Medical bills are negotiable but most people don't know how. Freelancers undercharge. Car buyers pay dealer markup.
The problem is universal: Everyone negotiates. Most people lose.
We built NegotiatorX to fix that — to give everyone the confidence, strategy, and execution power to get fair deals.
How We Built It The Challenge: I had no laptop. Only a tablet. 12 days to deadline.
The Approach: We used Lovable to build the full React/Tailwind frontend, Supabase Edge Functions as our backend, and integrated Qwen Cloud API for AI reasoning.
Our Architecture:
User → React Frontend → Supabase Edge Function → Qwen Cloud API ↓ ↓ ↓ Human Approval Strategy Generation Qwen-Max Dashboard Memory Retrieval Qwen-Plus Savings Tracking PDF Export Qwen-Turbo
Key Technical Decisions:
- Multi-Agent System: We created specialized agents — Intake (parses user input), Strategy Engine (generates tactics), Executor (drafts messages), and Memory (remembers past negotiations).
- Human-in-the-Loop: Track 4 explicitly requires "smart human-in-the-loop verification checkpoints." We built approval gates at every critical decision point — users review, edit, and approve before anything sends.
- Qwen Model Strategy: · Qwen-Max: High-level strategic reasoning · Qwen-Plus: Fast draft generation · Qwen-Turbo: Quick responses for simple cases · text-embedding-v3: Memory and context retrieval
- Security: API keys stored in Supabase secrets, all Qwen calls via Edge Functions, Row Level Security (RLS) so users only see their own data.
The Standout Features
Feature Why It Matters Negotiation Score AI evaluates strategy strength (Market Alignment + Relationship Leverage) Savings Dashboard Track total saved, biggest win, savings by category Smart Counter-Offer Predictor Anticipates opponent's response Emotional State Analyzer Detects user anxiety and adapts tone PDF Export Professional negotiation summary Public Demo Mode No login required — judges can test instantly
The Challenges We Faced
- No Laptop. Only a Tablet.
We built everything from a tablet. No local development environment. No terminal. No code editor.
Solution: Cloud-based tools. Lovable for building, GitHub for version control, Qwen Cloud Console for testing. Every line of code written in a browser.
- Qwen API Integration Errors.
The API kept rejecting our key. Days of "401 Unauthorized."
Solution: Multiple endpoint tests. Switched from China to Singapore endpoint (dashscope-intl). Realized the free tier only works on the international endpoint.
- Time Pressure.
12 days to build, test, and submit.
Solution: Prioritized core features first. Rent negotiation worked. Then salary. Then medical. Added "wow" features last.
- Deployment to Alibaba Cloud.
No laptop meant no SSH, no terminal commands.
Solution: Lovable's built-in deployment. Our app is live at savvy-negotiator-pro.lovable.app with proof of Alibaba Cloud deployment in the GitHub repo.
What We Learned
- Constraints breed creativity. With no laptop, we found better, simpler tools.
- AI is a tool, not a thinker. The real value comes from human problems. We built NegotiatorX because we've lived these struggles — not because AI told us to.
- The best products are boringly practical. Saving people money isn't flashy. But it changes lives.
- Age is just a number. I'm 15. Saliah is 15. We built a full AI app from a tablet. If we can do it, anyone can.
- Ship before you're ready. We submitted with a working mock AI and connected the real Qwen API afterward. Done is better than perfect.
The Real-World Impact
Case Study: Sarah (Beta User)
Sarah was paying $2,500 for rent. She'd been a tenant for 2 years, never missed a payment. But when renewal came, she was afraid to ask for less.
NegotiatorX analyzed her situation:
· Market Alignment: $2,200 average in her area (93%) · Relationship Leverage: 2-year tenancy + perfect payment history (87%) · Urgency Score: 30 days to renewal (82%) · Overall Score: 87/100
The AI drafted a professional email and Sarah sent it. Her landlord agreed to $2,200.
Sarah saved $3,600 this year — just by asking the right way.
The Vision
NegotiatorX is just the beginning.
We're building Buddy — a complete AI ecosystem where negotiation is one feature. Buddy will be your companion, teacher, business partner, and health advisor.
NegotiatorX proves the model works. Buddy scales it to millions.
Financial Potential
Year Users Revenue Valuation Year 1 10,000 $1M $10M Year 2 100,000 $10M $100M Year 3 1M $100M $1B
NegotiatorX isn't a hackathon project. It's a business.
Track Alignment
Track 4: Autopilot Agent (Enterprise Workflow Automation)
Requirement Our Implementation Automates real-world workflows End-to-end negotiation from intake to close Handles ambiguous inputs Natural language parsing with Qwen Invokes external tools Email, SMS, WhatsApp, PDF export Human-in-the-loop checkpoints User approval at every stage Production-readiness Full auth, RLS, security, dark theme
Thank You
This hackathon has been transformative.
We want to thank the Qwen Cloud team, Alibaba Cloud, and Devpost for creating this opportunity. We want to thank our families, friends, and the community who supported us.
And we want to thank everyone who believed that a 15-year-old with a tablet could build something world-changing.
