Selected products

Focused products.
Clear purpose.

Each product starts with one problem. If something does not help solve it, it does not belong.

Available on Google Play

DBMB

DBMB is an Android call silencer. Saved contacts ring. Unknown numbers stay quiet. No account, tracking or spam database.

Controlled access

Magentya

Magentya turns structured product lists into private B2B ordering spaces, without the overhead of a full ecommerce platform.

The approach

Designed to be understood.

Clarity starts with the first decision. It shapes the product, the interface and the promises we make.

Start with one problem

Every product starts with a problem we can explain in plain English.

Privacy built in

We collect less, depend on fewer services and avoid accounts when they are not needed.

Proof before promises

Real interfaces, clear limits and direct feedback matter more than inflated claims.

Journal

clearer technology.

The studio

Independent by design.

Design, product and code stay in the same room.

At Manthea Labs, design, interaction and implementation happen together. That means fewer handoffs, clearer decisions and products that stay close to the original idea.
