AI Sales Assistant (Joe) - Hackathon Project Summary

Inspiration

Suveer Dhawan was a client service associate and project lead at AlphaSights, working both client-side and customer-side, with lived experience of the pain points sales associates face every day. Part of the reason he left his job and moved to Melbourne was the redundant, repetitive work and expectation to always be online and respond to clients.

The daily grind of manually crafting cold emails, following up with prospects, and managing lead pipelines became overwhelming. Hours were wasted writing similar emails with slight variations, tracking responses manually, and losing potential deals due to missed follow-ups. The sales process was broken - too much human time spent on tasks that could be automated, leaving little time for actual relationship building.

This inspired him and the team to create Joe, your AI-powered sales assistant - a platform that eliminates the manual grunt work of cold outreach and transforms Google Sheet leads into booked meetings through intelligent automation.

What it does

Joe is a complete AI-powered SaaS platform that automates the entire sales outreach process from lead import to meeting booking:

🎯 Core Functionality

Google Sheets Integration: Import lead lists with one click using OAuth authentication
AI Email Generation: Creates completely unique, personalized emails for each lead using Google's Gemini AI - no templates, every email crafted from scratch
Intelligent Lead Scoring: Automatically classifies leads as Hot/Warm/Cold based on job titles, companies, and AI analysis
Automated Follow-up Sequences: Smart workflows that send contextual follow-ups based on responses and engagement
Response Monitoring: AI analyzes email replies and classifies them as Interested/Not Interested/Neutral/Out of Office
Calendly Integration: Seamlessly embeds meeting booking links in personalized emails
Analytics Dashboard: Beautiful interface showing campaign performance, response rates, and conversion metrics

🚀 Key Differentiators

Zero Templates: Every email is generated uniquely by AI, analyzing the recipient's role, company, and industry
True Personalization: AI identifies specific pain points for each lead's job title and industry
End-to-End Automation: From Google Sheets to booked meetings with minimal human intervention
Production-Ready Architecture: 8-file microservice design with proper error handling and logging

How I built it

The platform was built using a modern AI-first development approach:

🛠️ Development Stack

Frontend: Streamlit with modern gradient-based UI design
AI Engine: Google Gemini 2.0 Flash Exp for email generation and response analysis
Backend: Python with asynchronous operations and proper error handling
Database: Firebase Firestore for scalable data persistence
APIs: Gmail API, Google Sheets API, OAuth 2.0 integration
Hosting: Streamlit Cloud for deployment

🤖 AI-Powered Development

Cursor + Claude: Used AI-assisted development throughout the entire process, inspired by Dario Amodei's vision of AI-human collaboration
Iterative Problem Solving: Leveraged every ounce of technical knowledge to debug complex OAuth flows, API integrations, and async operations
Microservice Architecture: Designed 8-file structure for maintainable, scalable code

Challenges I ran into

🤒 Team Challenges

Lead Developer Emergency: Our lead developer got food poisoning on day one and never showed up, leaving us to figure out complex integrations ourselves
First-Time Everything: This was everyone's first hackathon and first software product we designed from scratch

🔧 Technical Challenges

OAuth Token Confusion: Gmail and Google Sheets tokens were mixing, causing authentication failures
AI Response Parsing: Gemini API returned raw JSON that needed proper parsing for display
Rate Limiting Issues: Initial model (gemini-pro) had severe rate limits, switched to gemini-2.0-flash-exp
Circular Import Dependencies: Complex module relationships required careful refactoring
Firebase Authentication: Setting up proper service account credentials and Firestore indexes
Email MIME Handling: Complex email composition with proper headers and formatting
Async Operation Management: Coordinating multiple API calls without blocking the UI

💪 Persistence Pays Off

Despite these setbacks, we never gave up. Each bug became a learning opportunity, and we systematically resolved every issue through AI-assisted debugging and collaborative problem-solving.
