## Overview

LossBook (now trading as Asterias) is a London-based insurtech that digitizes and standardizes the loss adjustment process for the commercial insurance market. The platform converts manual loss adjustment workflows into structured digital data, enabling structured capture at source from adjusters, engineers, and legal teams across every class of business.

The company was built in conjunction with key market stakeholders to ensure optimum structured data capture per class of business. Operating under the legal name Tenton Limited, LossBook addresses a fundamental data gap in the market where loss information has historically been captured in unstructured documents, preventing portfolio analytics and benchmarking.
