A SaaS landing built to score in the top decile of funded startups on Lighthouse.

GrowthSite Lab built SignalFlow — an AI-native decision intelligence workspace — on Next.js 15, Tailwind v4, Framer Motion 12, and a small R3F dashboard backdrop. Shipped at LCP 1.6s on mobile, CLS 0.03, Lighthouse perf 96. Most funded SaaS landings we audit sit between 50 and 70.

Performance is the new design language.

Five thousand nodes, 60fps, one Three.js scene.

A knowledge graph 3D visualization built on React Three Fiber + d3-force-3d + Vite. Instanced sphere geometry for nodes, batched line geometry for edges, auto-frame camera on first paint. Vertex colors disabled on the material — that's the landmine that costs a weekend if you miss it.

A tattoo studio website should respect the work, not compete with it.

Six services, a 6-image masonry gallery, WhatsApp-first booking, and a Trust Bar with the actual 271 reviews and 15K community. Italian + English copy, dark/gold palette, LCP under 2.5s on mobile.

NOCTURNE — one R3F canvas, one iridescent torus knot, 60fps on a phone. View-angle hue shift in a custom shader (no env map, no baked HDR, no 4 MB texture), 200 segments on one mesh, one draw call. GSAP horizontal Reel pinned on a single ScrollTrigger. Torch-cursor reveal via CSS radial mask + CSS-var coords, zero JS layout writes. 390 KB gzipped, LCP 1.9s mobile. Cool ultraviolet sister of HELIOS. GrowthSite Lab — premium web engineering studio.

1 operator. 7 R3F flagships shipped in 7 days. avg LCP 1.6s mobile, 60fps R3F across light + dark + high-key palettes. Pattern: precompute the heavy work at build time, lazy-mount the canvas, single owner per input event (R3F or GSAP, never both). One R3F base; light + dark + high-key palettes from the same engine. GrowthSite Lab — premium web engineering studio.

7 flagship homepages in 7 days. Week 1 wrap.

HELIOS closes the triptych: high-key glass prism with 6-beam spectrum dispersion. Light-palette R3F at 60fps mobile.

The pattern across 7 builds: precompute heavy work at build time, lazy-mount the canvas, and never let two libraries fight for the same input event.

Average LCP 1.6s. Zero HDR fetches.

ÆTHER ships iridescence + dispersion on the same meshPhysicalMaterial.

60fps on iPhone 15 Pro. The unlock is precomputing the iridescence cubemap at build time — one static asset, zero per-frame GPU cost.

Layered with Framer Motion 12 scroll choreography, WCAG 2.2 AA on the same scene.

5 GSAP-pinned cinematic scenes at 60fps mobile.

Cooperation pattern: Lenis owns wheel/touch input, ScrollTrigger reads from Lenis's scroll callback. Single owner = zero jank.

Iridescence is meshPhysicalMaterial physics, not a moving texture. No HDR environment needed.

Torch-mask cursor reveal: pure CSS mask, zero JS reflow per pointermove.
