With an early interest in Geography and GIS, Adrian Tear has invested in startup historical mapping company Cassini Limited.

Co-founded by Dan Re'em and others Cassini offers both a traditional offline print model and an online distribution mechanism for historical maps.

The online channel allows users to define their own area of interest to produce custom maps. Offline, Cassini's historical maps - produced on the same presses used for Ordnance Survey maps - are available through map shops, museums and a range of retail outlets.

It is expected that Cassini will continue to grow as a new generation of users become interested in genealogy, historical and family research.
