B2B SaaS — Outreach Platform
2024 - PresentConfidentialProspectFlow
ProspectFlow is a full-featured B2B outreach platform in the same space as Apollo and Instantly, built to give sales teams a single system for prospecting, outreach, and follow-up automation. The platform spans four core modules: a CRM for managing contacts and companies, a Sequences engine for trigger-based multi-step email automation, a visual Workflow builder for complex logic orchestration, and AI Agents that handle intelligent email replies. The entire system runs on an event-driven architecture powered by Inngest, ensuring reliable, scalable execution of automation at every layer.
Platform Modules
CRM — Contacts & Companies
Complete relationship management system for contacts and organizations.
- •Create, edit, and manage contact profiles with rich detail
- •Company management with linked contacts and activity history
- •Advanced filtering, search, and list segmentation
- •Contact engagement tracking and interaction timeline
Sequences — Automated Outreach
Trigger-based multi-step email sequence automation engine.
- •Multi-step sequence builder with configurable delays between steps
- •Trigger-based enrollment on contact actions and events
- •Conditional branching based on opens, clicks, and replies
- •Sequence analytics: open rates, reply rates, and step performance
Workflows — Visual Automation
Visual workflow builder for orchestrating complex automation logic.
- •Visual canvas with drag-and-drop logic flow construction
- •Conditional branching and multi-path execution
- •Integration with contacts, sequences, and external triggers
- •Workflow execution history and monitoring dashboard
Agents — AI Email Intelligence
AI-powered agents that handle email replies intelligently.
- •Context-aware agents that read and understand conversation threads
- •Automated reply generation tailored to conversation context
- •Email classification and priority-based routing
- •Agent performance monitoring and conversation insights
Challenges
- •Designing a scalable event-driven architecture that reliably handles concurrent workflow, sequence, and agent executions
- •Building trigger-based sequence automation that accurately responds to contact behaviour (opens, clicks, replies) in real time
- •Implementing AI email agents capable of understanding conversation context and generating appropriate, brand-consistent replies
- •Creating a visual workflow builder that supports complex conditional logic without sacrificing usability
- •Integrating multiple mailbox providers into a unified email management layer
- •Ensuring exactly-once event processing and idempotency across distributed workflow operations
- •Designing a CRM data model that scales for large contact lists while supporting fast filtering and search
Solutions
- •Architected the entire platform on Inngest for reliable event-driven workflow orchestration with built-in retry and idempotency guarantees
- •Built a sequence engine that listens to real-time contact activity events and triggers the appropriate next step automatically
- •Developed AI email agents using OpenAI that analyse full conversation history before generating contextual replies
- •Designed the workflow builder with a node-based canvas where each node type maps directly to a discrete Inngest function
- •Implemented a unified mailbox integration layer that normalises email operations across multiple providers
- •Leveraged Inngest's durable execution model to guarantee reliable processing even under failure conditions
- •Designed a relational data model with indexed filtering, full-text search, and efficient pagination for large datasets
Results
- •Delivered a production-ready B2B outreach platform with CRM, sequences, workflows, and AI agents in a unified product
- •Sequence automation enables teams to run multi-step outreach campaigns with zero manual follow-up effort
- •AI agents handle incoming email replies intelligently, improving response quality and reducing manual workload
- •Visual workflow builder allows non-technical users to orchestrate complex automation logic independently
- •Event-driven architecture ensures every workflow, sequence step, and agent action executes reliably at scale
- •CRM provides a single source of truth for all contact and company relationships across the platform
- •Established a scalable, modular foundation ready to support expanded outreach and prospecting features
