Marketo

💡

Inspiration

Every startup founder knows the struggle: you're in back-to-back meetings discussing exciting milestones—a new funding round, a product launch, a major partnership—but by the time the meeting ends, that marketing opportunity is lost in a sea of notes and to-do lists. The problem: Companies have marketing-worthy content hidden in their everyday conversations, but extracting, validating, and distributing it requires hours of manual work. Our vision: What if AI could listen to your meetings, automatically identify marketing opportunities, generate personalized social media content for your team, and get it approved—all without lifting a finger? That's where Marketo was born. We wanted to build a no-code platform that turns meeting transcripts into viral social media campaigns, making marketing automation accessible to everyone. 🎯

What it does

Marketo is an intelligent, no-code marketing automation platform that transforms meeting transcripts into ready-to-post social media content through a visual workflow builder. The Complete Flow: 📝 Paste Meeting Transcript User pastes their meeting notes or transcript into the platform 📝 Paste Meeting Transcript User pastes their meeting notes or transcript into the platform 🤖 AI Content Extraction (ChatGPT) ChatGPT analyzes the transcript and extracts marketing-worthy content Identifies funding announcements, product launches, milestones, achievements 🤖 AI Content Extraction (ChatGPT) ChatGPT analyzes the transcript and extracts marketing-worthy content Identifies funding announcements, product launches, milestones, achievements ✅ AI Validation (ChatGPT) Validates if the content is truly marketing material Filters out non-promotional content automatically ✅ AI Validation (ChatGPT) Validates if the content is truly marketing material Filters out non-promotional content automatically ✉️ Smart Approval Request Sends email to productivity303@gmail.com with extracted content Asks: "Do you approve?

How we built it

Architecture Overview Tech Stack Frontend React 18 - Modern UI framework React Flow - Visual workflow builder with drag-and-drop TypeScript - Type-safe development TailwindCSS - Utility-first styling Vite - Lightning-fast build tool pnpm - Efficient package management Backend Go 1.21 - High-performance backend Temporal SDK - Workflow orchestration engine Fiber/Mux - HTTP routing PostgreSQL - Workflow state persistence Docker - Containerized deployment AI & APIs OpenAI GPT-4 - Content extraction and generation Nano API - AI-powered image generation SendGrid/Gmail API - Email automation Webhooks - Real-time approval handling Key Components 1. Visual Workflow Builder (Frontend) Each node is fully configurable with: Dynamic property forms Variable substitution ({{variableName}}) Conditional logic API endpoint configuration 2. Workflow JSON Export The visual workflow compiles to executable JSON: 3. Temporal Workflow Engine (Backend) 4. Activity Implementations ChatGPT Integration: Nano Image Generation: Email Approval with Webhooks: 🚧

Challenges we ran into

1. Dynamic Workflow Execution Problem: How do we execute user-defined visual workflows without hardcoding every possible combination? Solution: Built a dynamic workflow interpreter in Temporal that reads the JSON workflow definition and executes activities based on node types. This allows infinite workflow combinations without code changes. 2. Human-in-the-Loop Approvals Problem: Workflows need to pause and wait for email responses (could be hours/days). Solution: Used Temporal's Signal feature. When a user clicks approve in the email, a webhook sends a signal to resume the workflow exactly where it left off—even if the worker crashed! 3. Variable Substitution Across Nodes Problem: Users need to reference outputs from previous nodes (e.g., {{approvalResponse.employeeCount}}). Solution: Built a variable resolution system that: Tracks all workflow variables in state Parses {{variableName}} syntax Replaces with actual values at runtime 4. AI Prompt Engineering Problem: Getting consistent, usable output from ChatGPT for content generation. Solution: Crafted specific prompts with structured output requirements: 5. Real-time Workflow Monitoring Problem: Users can't see workflow progress in real-time. Solution: Implemented WebSocket connection between frontend and Temporal, streaming workflow events to the UI for live updates. 🏆

Accomplishments we're proud of

✅ End-to-End Automation Built a complete marketing automation pipeline from transcript → AI processing → approval → distribution—fully automated! ✅ No-Code Visual Builder Created an intuitive drag-and-drop interface that anyone can use to build complex workflows without writing code. ✅ Production-Ready Architecture Implemented enterprise-grade workflow orchestration with Temporal, ensuring reliability, fault tolerance, and scalability. ✅ AI Integration Excellence Successfully integrated multiple AI APIs (ChatGPT for text, Nano for images) with intelligent prompt engineering. ✅ Human-in-the-Loop Done Right Solved the challenging problem of pausing workflows for human approval and resuming seamlessly. ✅ Reusable Node System Created 9 custom workflow nodes that can be mixed and matched to create infinite automation possibilities. 📚
