SerenX. Website design & development for defense tech
About
SerenX builds autonomous interceptors a single operator can carry and launch. SX-1 is an electric, hand-launched missile; SX-2 brings the same autonomy to a turbojet. Around them sits a software family: KALDREX for command, Primorex for targeting, Solundra for flight control and the Delvix API for plugging into any C2.
Challenge
SerenX came to us with two missiles, four software products and a new name, but no site that could explain any of it. The audience is defense buyers and investors: technical, skeptical and short on time. The site had to read as serious hardware rather than a startup landing page, and show products that are still partly in development without overselling them.
Solution
We built the site from scratch, from first concept to production code. Every page tells one story on scroll: the missile is drawn as a blueprint until the render takes over, and each app works like a live instrument, from the KALDREX map to the Primorex seeker HUD. We designed the missiles too. Four liveries for SX-1 and SX-2, from the signature orange to field colors, painted onto the 3D model and carried through the whole site.
Website development
Our team built the site in house with React, TypeScript and Vite. Scroll is driven by GSAP ScrollTrigger and Lenis, the missiles live in Three.js, and the halftone scenes run on WebGL. Media streams from Cloudflare R2, forms and security headers run on Netlify, and every page works on desktop, tablet and mobile. From kickoff on May 8 to launch on October 12, serenx.com went live in five months, and the repository and hosting were handed over to the client.
