KineDB

KineDB is a database engine designed to run both on local devices and in backend infrastructure, with offline sync built into the database itself. Founded by Axel Loewenhoff and Allan Zimmermann, the company raised €850,000 in pre-seed funding led by Superhero Capital, as reported by Tech.eu and RuntimeWire on October 30, 2026. Its tagline: "Your servers are optional."

The idea

Offline-capable apps today usually stitch together a local store (e.g. SQLite on the device), a server database, and a separate sync layer to reconcile them. KineDB's bet is that one engine can play all three roles, which would simplify the architecture for local-first and mobile apps.

Why now

The founders frame it around AI reshaping software development: as more code is generated quickly, simpler infrastructure with fewer moving parts becomes more valuable.

Caveats

KineDB is at a pre-seed stage; the proof will come from real deployments showing the single-engine design holds up under production workloads.

Who should care

• Developers building local-first, mobile or field apps that must work without connectivity.
• Teams tired of maintaining a separate sync service between device storage and the backend.
