Zentek StudioWho you'll reach
Zentek Studio is a free 2D drafting + 3D solid‑modeling app. Its users are a focused, hard‑to‑reach professional audience — the kind generic ad networks can't target well.
Engineers & designers
Mechanical, product and architectural designers drafting real parts and assemblies.
Makers & fabricators
3D‑printing, CNC and workshop users who buy tools, materials and machines.
Long, focused sessions
Desktop work sessions run for tens of minutes — your ad is on screen the whole time, not a scroll‑past.
A growing beta audience. Zentek Studio is in active public beta and its reach is climbing. Ask us for current install, session and impression figures for your campaign window — we'll share the latest numbers so you can size a plan with confidence.
Where your ad lives
A dedicated advertising panel built around the standard 300 × 250 “medium rectangle” pinned in the app's right‑hand dock and visible for the entire work session — not buried in a feed.
One clean slot, done right
- One ad at a time — no clutter, full attention on your creative.
- 60 seconds on screen before it rotates to the next advertiser.
- Click‑through opens your landing page in the user's browser.
- Static or animated — a still image or a looping animation, your call.
How it works
You buy impressions, delivered over a window you choose. How fast you want them sets your live share of the rotation — a bigger goal or a shorter window means a bigger share, until your goal is met.
- Tell us your goal. How many impressions, over how many days — we work out the rest.
- Send your creative + link. An image, an animated GIF, or an HTML5/MP4 file we turn into one — plus your click‑through URL.
- Go live. Your ad enters the rotation and serves worldwide, or your target audience, until it reaches your impression goal, then stops.
- Get reporting. Impressions, clicks and click‑through rate — no vanity metrics.
The rotation is exactly proportional: pay for twice the delivery rate and you're shown exactly twice as often, and the same ad never plays back‑to‑back. Impressions are only counted while the panel is actually on screen — so you pay only for real views.
Creative formats
Send whatever you have — we'll get it into the slot. Animated banners are welcome.
| You send | What we do | Notes |
|---|---|---|
| PNG / JPEG | Displayed as‑is | Best for logos, product shots, sharp text |
| Animated GIF | Plays in the panel | Looping motion, up to ~6 s |
| HTML5 banner | We render it to an animation for you | No extra work on your side |
| MP4 / WebM | We convert it to an animation for you | Muted, short loop |
Size
Design at 300 × 250 px (the standard “medium rectangle”).
It's shown ~260 px wide — scaled to fit, aspect preserved so a 300 × 250 file stays crisp.
Weight
Keep it under a few hundred KB.
Animations ~15 fps, ≤ ~6 s.
Link
One click‑through URL: it opens in the user's default browser.
Brand‑safe & privacy‑first
🛡️ A professional context
Your ad appears inside a focused engineering tool — no user‑generated feed, no risky adjacencies, no auto‑play video shouting over their work.
🔒 No creepy tracking
Ads are non‑personalized. We don't build user profiles, set cookies, or collect personal data, and we never resell anything. It's clean, GDPR‑friendly reach — and a story you can stand behind.
Pricing
Straightforward pay‑per‑impression — you're billed only for ads actually shown.
€7 per 1,000 impressions (founding rate). Pick a goal and a window, we deliver it.
You get every impression you pay for. The goal is a promise, not a maybe — the window is our target pace, not a hard stop. If traffic runs slow, your campaign keeps showing until all your impressions are delivered; if it runs fast, it finishes early. You pay once, for exactly what you bought.
Packages
| Package | Impressions | Price | Best for |
|---|---|---|---|
| Starter | 10,000 | €70 | A first test of the audience |
| Standard | 25,000 | €175 | A light, always‑on presence |
| Plus | 50,000 | €350 | A steady, visible campaign |
| Pro | 100,000 | €700 | A strong, sustained share |
| Premium | 150,000 | €1,050 | A dominant presence |
Express delivery: +30%. By default your impressions spread over ~30 days for a steady presence. Add Express to concentrate the same impressions into a short burst (about a week) for a much bigger live share — ideal for a product launch or an event.
Discounts: −15% for an annual commitment. Custom rates for large volumes and for non‑profits / open‑source projects.
No oversell: we confirm the impressions available for your dates before you commit — so your goal is always deliverable.
Prices in EUR, excl. VAT, at €7 / 1,000 impressions. Express delivery adds 30% for the faster pace and bigger share; standard delivery is the base rate. The window is a target pace, not a deadline — you always receive your full impression count.
