Natla Technologies
Natla Technologies is a company presumably founded and run by Jacqueline Natla, formerly of Atlantis. At one point in Tomb Raider, Lara breaks into Natla Technologies and discovers Natla's interest in the St. Francis Folly. A cut scene shows the Natla Technologies headquarters as a skyscraper set in a cityscape, but it is not immediately clear in which city (or indeed in which country) the building is situated. It's presumed to be either Los Angeles or New York City.
It is not clear what products or services the company offers, but they are involved in mining (see Natla's Mines), computer manufacturing (the laptop Larson Conway presents in TR1 is engraved with the Natla Technologies logo) and, possibly, genetic engineering.
Crates bearing the Natla Technologies logo are visible in Tomb Raider and Tomb Raider Anniversary, while crates in Tomb Raider Legend are adorned with the Natla Industries logo, most likely a subsidiary.
