Celestial believes the tech era calls for human-centered products. We build education and entertainment suited to our time — to help people grow and to spark joy. We respect every team member and care for every user. We earn wealth the right way, embrace harmony in diversity, and believe good is only real when it's good for everyone.

With this in mind, our first education product is SQL Hero — a mobile app where you learn SQL by doing.

Learn SQL by Doing.

Why Support Us?

We're building something different.

🎮
Game-Based Education
12 years of curriculum in roughly 6 years (~2x speed), only what's useful
📚
Beyond Academics
Not just traditional subjects — also social skills: relationships, teamwork, business
🤖
Light AI
AI explains your errors, not replaces teachers. Moderate tech delights; excessive tech destroys
💰
Profit Sharing
5% of net income becomes Celestial Store Credit for early supporters
🎯
One-Fee Model
Pay once, own the complete product
🧘
Work-Life Balance
In the internet & AI era, 40+ hour weeks are unnecessary and outdated; we run a 30-hour work week, WFH when possible
💎
People Are Assets
Employees are Celestial's assets, not liabilities; they deserve high pay — not just to get by, but to live and enjoy life (a value for when we hire)
🐢
Human-Paced
Mental bandwidth is finite; no one must chase the latest tech. We build at a human pace, not chasing trends

"Celestial believes humans are not GPUs. We build things that let humans rest easy."

Game Vision

Games are the second major category in our product line. Here are our design principles.

⚖️
Fairness First
Optimal balance, always able to comeback (like Overwatch 1), no snowball mechanics
🎮
Fair Play, Fair Pay
Core gameplay free, competitive multiplayer paid. Every game includes a one-fee option — pay once, own the full experience. No gacha, no endless grind.
🌐
Direct PC Distribution
PC version on our own launcher (like Battle.net), skipping the Steam 30% fee. Result: players pay less, team earns more, and we control quality end-to-end. Mobile/tablet: App Store / Google Play.
📊
Moderate Difficulty
Too high: players get intimidated. Too low: players get bored.
🎯
Casual & Semi-Pro First
Prioritize casual and semi-pro players — they are the foundation
