Autumn Radtke, an executive with the troubled online currency company Bitcoin, was found dead in her apartment on February 28.
She was 28 years old.
Radtke - who is being described as the "American CEO" of Bitcoin, despite such a position not technically existing - was discovered inside her Singapore residence, with local authorities awaiting toxicology test results to determine the cause of death.
But she is believed to have taken her own life.
Douglas Adams, the chairman of First Meta, confirmed via statement that his colleague has passed away.
"The First Meta team is shocked and saddened by the tragic loss of our friend and CEO Autumn Radtke," Adams said. "Our deepest condolences go out to her family, friends and loved ones. Autumn was an inspiration to all of us and she will be sorely missed."
Radtke worked under Richard Branson at Virgin Charter at 22 years old and also as a freelancer for Apple.
She was a native of suburban Milwaukee.
The collapse of the major bitcoin exchange Mt. Gox in Tokyo this week has drawn renewed attention to the currency, whose standing in the financial community continues to fall each day.
Mt. Gox, once the world's dominant bitcoin exchange, recently filed for bankruptcy after saying it lost around 850,000 bitcoins, worth $400 million, due to hacking.
