We build complex sites on Next.js + Three.js — bespoke website design, premium product interfaces, and AI funnels with custom animation. They pass Core Web Vitals and ship SEO-ready, with a 2D fallback for low-end devices. Live in as little as 2 weeks.
Three years ago, any site with heavy interactivity looked like a breakthrough. Today interactivity — a 3D configurator, a scrollytelling story, motion design — isn't a wow moment. It's a judgment call. If your product is complex or premium, or you want to stand out in a crowded niche, it pays off. If you run a utilitarian SaaS, that money is better spent on copy.
Luxury, hospitality, automotive, real estate, jewelry, medical websites. Buyers expect to feel something and spend time with the product before they commit.
Hardware, medtech, industrial gear, education products. When the idea is easier to show in 3D than to explain in text.
When every agency in your category looks the same, one site with thoughtful interactivity sets you apart on sight.
If people show up to finish a task in a minute (grab a link, a tracking number, a balance), interactivity just gets in their way.
High-volume catalog, thin margin per item. The buyer cares about price, stock, and delivery time.
Launching a beautiful site and forgetting about search is the fastest way to burn the budget. Without SEO and AI-answer visibility work, real customers never find you.
Recognize yourself in one of the categories above? We won't talk you into paying for 3D and custom shaders.
Corporate sites, landing pages, online stores, or a redesign of one you already have. Few static sections — plenty of scenes that react to scroll and cursor.
Dashboards, web apps, CRM, SaaS — with a premium UI. An interface on par with Linear, Stripe, Vercel, not a templated MVP.
Site + AI agent + CRM, wired together. The interactive site draws people in and qualifies the lead; the AI agent runs the conversation. The handoff from scene to chat keeps the experience intact.
We pick the stack to fit the job. The default set is below: React and Next.js development, headless CMS, Three.js. Self-hosted deploy is standard — code, assets, and logic stay on your servers.
When the product calls for it, we layer extra tooling over the base stack. We decide this at the architecture stage.
A given project may need something else. We decide this at the architecture stage.
The big trap with interactive sites: gorgeous on desktop, slow on a phone, and search engines see nothing. 53% of mobile visitors leave a site that takes longer than 3 seconds to load. We build speed and SEO into the architecture from day one.
The first screen opens instantly; the other scenes load as you scroll. We compress heavy 3D models 5–7x with no visible loss in quality.
We measure the device's power in milliseconds. Strong devices get the full scene, weaker ones a lighter version, and the oldest a flat version with no 3D.
The page's text and structure are ready before the heavy effects fire — search engines see everything. The 3D loads on top and stays out of indexing's way.
Many sites block AI bots by default — we open access explicitly and make sure the content is readable. Every key platform gets in:
The classic SEO building blocks — set up by default on every project.
From brief to production. Timing depends on how deep the interactivity goes. A simple landing with 1–2 interactive scenes runs 2–3 weeks. A site with full scrollytelling, 4–6 weeks. A complete AI funnel, 6–8 weeks. Bespoke immersive builds run longer — up to 2–4 months.
Hover a row to open the details of that stage.
We break down the job: business goal, ICP, competitive context, performance and SEO requirements. We put together a mood board (3–5 references, each with a reason). Then we lock the direction: marketing site, product UI, or AI funnel.
We build the design system: typography, grid, color palette, base components. We put together a hero-scene prototype as an animated mockup. We agree on the tone of voice and the character of the interactivity.
We build the site's foundation, write the animations and 3D scenes, and wire in the backend and AI layer if it's needed. Alongside that we tune load speed, search-engine markup, and AI-bot access.
We test speed and smoothness on 5 devices: a top iPhone, a mid-range and a low-end Android, a MacBook, a Windows laptop. We check every popular browser. All the key metrics land in the green on phone and desktop.
We deploy the site to the server. We hand over the docs and train your team (4–6 hours). Support after that runs on the package you pick.
We lock every price at the time you book. Anything beyond that is only agreed-on scope changes. The ROI calculator estimates payback for your own numbers in a minute. Bundle the build with SEO + GEO and you get a discount.

The five points below are what we keep seeing in the competitor projects that land on our desk for rework. We sidestep each one from the start of every new build.
Heavy interactivity with no cap ends with a 30 MB first screen: the visitor on a phone waits 8 seconds and closes the tab. We set a page-weight budget and a frame-rate target up front, so the site stays fast a year from now.

If the heavy interactivity loads first, the crawler never sees the page content and drops it from the results. With us, text and structure are ready before the effects fire — the crawler sees all the content, and the 3D loads on top without blocking indexing.
The scene looks perfect on a MacBook but runs at five frames a second on a budget Android and stutters. We measure the device's power at the start and serve the right level of detail: the full scene for strong devices, a lighter one for weak ones, a flat version with no 3D for the oldest.
The designer draws for desktop, the developer builds for desktop, the phone gets checked at the end — and half the scene gets redone. We test on a phone from day one: finger gestures instead of a mouse, no hover-only effects.
The site ships without a CMS, so the marketer can't change a headline without a developer. Six months later the copy is stale. We wire in a CMS by default so your team can edit text, images, and banners themselves. The complex interactivity stays with the developer.
Nine questions we get most often. Don't see yours? Message the CTO or CEO directly.
Yes, in an adapted version. On load, we measure the device's power in milliseconds. A modern phone (iPhone 14+, flagship Android) gets the full scene. A mid-range one gets a lighter version. An old or budget phone gets a flat version with no 3D. The content and functionality are the same in every variant — only the visual layer changes.
It depends on the approach. The median website in 2025 weighs 2.5–2.9 MB (HTTP Archive). A well-optimized 3D scene adds 0.5–1.5 MB on top of that: source models exported from Blender at 5–50 MB get compressed 10–20x through Draco with no visible loss. The finished interactive page lands at 3–5 MB — on par with a regular site that has a video background or large photos. The heavy parts load after the first screen, so the visitor never waits for the whole scene before seeing the page.
On its own, 3D doesn't lift your rankings — Google gives no bonus for interactivity. But with the right architecture, it doesn't hurt them either. The page's text and structure are in the HTML before the heavy effects load, so the crawler sees all the content. The 3D loads on top and never blocks indexing. Search-engine markup and AI-bot permissions are set up by default. The real job is passing Core Web Vitals (LCP under 2.5 seconds): once the page clears them, ranking comes down to content and links, not whether the page has 3D on it.
Yes. We wire in a CMS by default — your marketer changes the text on the site without calling a developer.
It depends on how much interactivity is involved. A landing page with one 3D scene runs 2–3 weeks. A corporate site with an interactive catalog or configurator, 4–6 weeks. A fully custom immersive project with several scenes and your own assets, 2–4 months. Before we start, we lock a calendar with milestones — you see what ships and when.
It depends on scope and how deep the interactivity goes. A landing page with light interactivity starts at €2,500, a multi-page site or premium interface at €6,000, a full WebGL scene or AI funnel at €20,000. We lock the exact quote at the audit stage, fitted to your needs, with no hidden charges beyond the agreed scope. The ROI calculator estimates payback in a minute.
Yes. We take models from Blender, Cinema 4D, Maya, ZBrush in GLTF / GLB / FBX / OBJ. We adapt them for the web: geometry compressed through Draco (usually 10–20x with no visible loss) and textures optimized so the model loads fast. If you already have rendered stills or video assets, we fold them in as extra layers.
Support — from €500/mo: a block of hours for regular updates, fixes and changes; priority queue, response within 24 hours. The first week after launch is free.
We do, but only when a rebuild is justified. People often come to us asking to rewrite everything from scratch, and after the audit it turns out targeted work is enough: speed it up, redo the first screen, adapt it for mobile. We tell you straight how much work you actually need, and we don't sell a redesign for its own sake.
We'll go through your goals and your current site (if you have one), size the budget against the scope, and send back a short report with a proposed architecture. No strings attached.
