Maritime artificial intelligence developer Nautilus Labs has secured $11m in financing from a group of firms led by a Microsoft-backed fund.

The New York-based start-up, which whose customers include Dorian LPG, Teekay and Eagle Bulk Shipping, announced the deal Tuesday, bringing their fundraising total to $14.5m.

"Nautilus is creating an economic imperative for shipping businesses to reduce their fuel consumption," chief executive Matt Heider said in a statement.
