LaunchWise
GitHubAll-in-one product launch and marketing automation platform for creators.
Overview
LaunchWise centralizes waitlist management, email automation, and conversion tracking into a single dashboard, streamlining the go-to-market motion for indie hackers.
The Problem
Founders struggle to coordinate multiple fragmented marketing channels (Mailchimp, Google Analytics, Typeform) during critical product launches, leading to lost leads and poor conversion visibility.
System Architecture
Engineering Trade-offs
Chose Serverless functions over a long-running Express server to optimize for cost and auto-scaling during traffic spikes, accepting slight cold-start latency.
Lessons Learned & Future
Production Learnings
Third-party email delivery services (like Resend/Sendgrid) have strict limits for new accounts. Had to implement queueing and batching to avoid API rate limits.
Future Improvements
Integrating a Stripe billing portal for premium tiers and webhook support for Zapier integration.
Database Layer
PostgreSQL for relational data integrity regarding users, waitlist entries, and email campaign statuses.
API Design
Edge API routes for the public waitlist capture to handle high concurrency during viral launches. Standard REST for the authenticated dashboard.
Security Decisions
1. Implemented strict rate-limiting on the waitlist endpoints to mitigate bot spam. 2. Server-side validation of all form inputs to prevent SQL injection and XSS.
Scale & Metrics
Waitlist API endpoint handles 1000 requests/sec with average 40ms response time.
