CASTADI is a cloud-based Digital Out-of-Home marketplace — it connects advertisers who want real-world attention with the shopkeepers, cab drivers, and venue owners who already have a screen. No booking calls, no manual reconciliation, no guessing whether an ad actually played.
An auto-rickshaw dashboard, a cafe counter, a hospital waiting room — these screens exist whether or not an ad is running on them. On the other side, a brand trying to reach the same people usually has two bad options: a billboard they can't target, or a mall kiosk they can't verify.
CASTADI closes that gap. Screen owners across autos, retail, hospitality, healthcare, offices, and malls list their inventory once; advertisers discover, book, and pay for exactly the screens that match their audience — with performance data that comes from the screen itself, not a monthly PDF.
Every play is logged the instant it happens on the screen — an advertiser sees what actually ran, not an estimate.
A screen owner shouldn't need a sales team, and an advertiser shouldn't need a phone call — both run entirely from the dashboard.
Verification, pricing, booking, and payouts are the product — the marketing site is just the front door.
A web console for both sides of the marketplace, an API that owns booking and payouts end to end, and a native player that keeps running even when the screen's internet doesn't.
One app, three roles — advertiser, screen partner, and admin — behind a single sign-in.
A modular service handling auth, bookings, pricing, payments, and revenue payouts.
Runs on the physical screen — pairs once, then plays and syncs on its own.
Whether you're building a brand or building screen revenue — it starts with one form.
