In 2017-2018, Black Legend Capital acted as a consulting advisor to Ameritek Ventures, a fiber optics manufacturing company, publicly traded in the U.S. and headquartered in Las Vegas. Ameritek Ventures manufactures the preforms used to make fiber optics. The company had rapidly gained market share against the single supplier monopolizing the fiber optics preform market, by providing a second sourcing option, reducing risk and price.

At the time of the transaction, Ameritek Ventures was in advanced negotiations to supply fiber optic preforms to many companies around the world, including Ericsson.
