Hamburg maritime tech start-up NautilusLog is stepping up its war on paperwork in shipping after closing its second seed financing round.

The company, co-founded by entrepreneur Otto Klemke, has raised €1m ($1.2m) in a deal with lead investor NBank Capital, a domestic fund and various "business angels". These include another unnamed investment company.

The cash will be used to expand the team and platform for new services and enable the company to serve "rapidly growing global customer demand", NautilusLog said.
