We build and run technology businesses

Portanova is the group behind Repairo, Cardine, and Portanova Labs. We build our own products and keep running them after launch. Through Labs, we put the same software and know-how to work for other companies.

Our approach/ 001
[ 01 ]

We build what we'd run ourselves.

Every product starts from a workflow we know first-hand, not from a model looking for a use.

[ 02 ]

We operate what we ship.

The products stay ours after launch. We run them, support them, and keep improving them.

[ 03 ]

Each build strengthens the next.

One identity and billing layer, one data and AI layer, one deploy pipeline. Cash flow from live platforms funds what comes next.
