Who uses TrueLock?

One product ? three ways to monetize access control.

📈

Cappers and Traders

People do not trust your calls. They say you edit after the fact.

Lock your prediction before the event. The capsule opens after the match so everyone sees you knew first. Or sell the password in advance to paying users.

? Unlock after the event OR ?? with a purchased password

🏪

Stores, Cafes, Restaurants

The customer came once and disappeared. Ads are expensive with weak results.

Send a reward capsule after purchase. It opens only in your venue and only until week end. The customer physically returns ? no ad budget needed.

?? Only at the geo point AND ? before expiry date

⚡

Flash Sales and Drops

You launch a promo and nobody reacts. Users see hundreds every day.

Send the capsule in advance to all your audience. The offer appears at 18:00 and disappears at 18:05. People wait with timers. Hype without ad spend.

? Only from 18:00 TO 18:05 ? then closed
