Summary & Pricing

Executive Summary

Investment thesis

Unit economics (breakeven at 16 users, 94.8% gross margin at scale) support sustainable pricing and growth without surprise price hikes. The variable cost per user ($1.61/month) is 75% lower than Fargate-based alternatives thanks to EC2 capacity providers, bridge networking, and pool pre-warming. Every dollar of subscription revenue above breakeven flows almost entirely to margin.

For you: start free, scale with you

Basic is free — simulation and strategy builder included. Pro (NT$999/mo) unlocks real trading across Taiwan, crypto, and (soon) US markets. Our unit economics mean we are built to last: no surprise price hikes, and we grow with you.

4pass operates with 94.8% gross margin at scale, driven by shared EC2 infrastructure (60 workers per instance), serverless orchestration (~$8.50/month total Lambda cost), and managed data services that auto-scale with demand. The platform breaks even at 16 paying users and achieves 97.5% net margin at 10,000 users.
