OUR STORY

Built by people who design
real buildings

Zero Optimize was born from a frustration: every architect we knew wanted to design energy-efficient buildings, but the tools made it cost weeks of expert time. We built the tool we wish we'd had.

🌍

Our Mission

Democratize building energy modeling. Give every architect, engineer, and developer access to professional-grade calculation — without the price tag or learning curve.

🔭

Our Vision

By 2030, every new building in tropical and emerging markets is designed with real-time energy modeling — making Net-Zero the default, not the exception.

💎

Our Values

Precision: Engineering accuracy without compromise.
Speed: Months → minutes.
Access: Premium tools, fair price.

Founders

Built by the people who use it daily

A working architect and a sustainability engineer — not consultants. Every line of the calculation engine reflects how real projects are designed in tropical climates.

Our Journey

From frustration to platform

2024

The First Question

Why does designing one energy-efficient building take a team of engineers three weeks? We started building our own tool.

2025

The Free Prototype

Released zeboptimiz.netlify.app and envelopmodify.netlify.app for free. Hundreds of architects and engineers in Thailand validated the demand.

2026 Q1

Going Global

Incorporated Zero Optimize Co., Ltd. Launched paid tiers, multi-language UI, and global payment processing. Expanding into India, GCC, and Southeast Asia.

2026 Q3

BIM Integration

Native plugins for Revit, Rhino, and ArchiCAD. API access for enterprise customers. Ongoing ASHRAE 140 validation.

2027

AI Optimization

Auto-suggest optimal envelope materials based on climate zone, budget, and embodied carbon — powered by ML trained on real project data.

2028+

National Scale

Platform partnership with regulatory bodies and Green Financing programs. Building energy data infrastructure for Net-Zero national goals.
