NUMO: Carbon Intelligence, Built From Scratch
An AI-powered carbon accounting platform we designed and built in-house as Noissime — marketing site, SaaS app, and full Scope 1-3 tracking, hand-coded with no frameworks. It has since rebranded to NUMO and grown into its own independent business.

The Vision
We built this platform in-house as Noissime — the name was "emission" backwards — an AI-powered carbon accounting platform that makes emissions tracking simple for any business. Not just a marketing page: a credible, fast platform that sustainability managers and CFOs trust with their data.
It covers full Scope 1, 2 and 3 tracking under the GHG Protocol. It has AI-powered plain-language input, supplier automation, and reports for CSRD, ESRS, SBTi, CDP, TCFD, GRI, ISO 14064, ESOS, and SFDR. We built the platform and its whole web presence from scratch.
The strongest endorsement of the work is what happened next: the product outgrew us. It has rebranded to NUMO and now operates as its own independent business. We build websites and platforms to commercial standard — this one became a company.
What We Built
Hand-Coded Static Site
Pure HTML, CSS, and vanilla JavaScript. No React, no Next.js, no build tools. Every line written by hand. The result: a 66KB homepage that loads in under a second.
30+ Page Architecture
Feature pages, industry pages, rival comparisons, pricing, blog posts, and compliance docs. All built for search engines and AI to find easily.
Interactive Dashboard Previews
HTML5 canvas hero animation and mock dashboard views that show the product without a login. Prospects see value before they sign up.
Compliance-Ready Content
Ten compliance badges, clear feature docs, and structured data on every page. Built so buyers and green managers can check claims fast.
Lightweight by Design
WebP images, SVG logos, deferred JavaScript, and no third-party trackers. The site lives by the same rules it promotes: low carbon per page view.
SEO & AI Foundation
Full JSON-LD data, Open Graph tags, semantic HTML, and clean URLs. Six blog posts and rich content pages built for organic search from day one.
