Overview
SAVE made speed legible: fast source delivery, aggressive filtering, and interfaces built for rapid scanning.
Korean investors were getting U.S. market news after the market had already reacted.

Problem
The Feed Was Fast. Understanding Was Not.
Investors received thousands of headlines with little help deciding what mattered to their portfolio right now.
- 5–10 minute latency behind US sources
- Little portfolio or sector filtering
- Critical analysis remained locked in English
Core decision
Design for the Three-Second Scan
The desktop workspace keeps source, urgency, headline, market context, and live signals visible without opening every story.
- Priority and source are visible in the row
- Feed and market signals stay side by side
- Density serves monitoring, not decoration
Product system
Desktop Monitors. Mobile Moves.
Mobile keeps the same information model but changes the rhythm: quick feed, event planning, and personal settings designed for one hand.
- Feed cards preserve source and related ticker
- Calendar connects events to market context
- Navigation keeps five high-frequency surfaces within reach
Impact
Week 1: 1K → Week 4: 100K
With almost no paid marketing, fast delivery and clear scanning drove word of mouth.

Reflection
Key Learnings
Speed is a Feeling
Thirty seconds versus five minutes changed how alive the product felt.
Small Teams Need Hard Priorities
Every surface had to earn a week of engineering time.
Launch Copy Sets the Product Contract
The site promised speed; the first session had to prove it.
