0xGrantHunter

About the Project

0xGrantHunter is a fully autonomous, multi-agent system built with Google’s Agent Development Kit (ADK) that eliminates the biggest pain point for small businesses and startups: finding and applying for non-dilutive funding.

What inspired us
Small businesses waste hundreds of hours manually searching Grants.gov, state portals (OEDIT, Denver Economic Development, etc.), SBIR/STTR programs, and foundation directories. We wanted to turn that painful scavenger hunt into a 60-second conversation.

What we built
A production-ready agent that:

• Learns your business via conversation or uploaded business-plan PDF (multimodal)
• Maintains resumable sessions with Firestore
• Dynamically searches federal (Grants.gov API), state (OEDIT, Denver), SBIR/STTR, and NGO/foundation opportunities using location-aware tools
• Drafts application text with a WriterAgent
• Reviews for accuracy and hallucinations with a ReviewerAgent
• Stores long-term grant knowledge in MongoDB Atlas (MCP-ready)

How we built it
We collaborated in real time with Grok (xAI) to design the architecture, generate the full ADK multi-agent codebase, and produce production Terraform + Cloud Build assets. The entire system deploys in one command to Google Cloud.

Challenges we faced

• Orchestrating reliable multi-agent workflows with resumable sessions
  
• Securely handling secrets (Gemini keys + MongoDB Atlas URI)
  
• Building location-aware grant search that actually works across federal/state/NGO sources
  
• Keeping the agent truthful and hallucination-free under tight hackathon time constraints

We learned that Google ADK + Cloud Run + Firestore is an incredibly powerful stack for shipping production-grade agents extremely fast.
