First Meta extended its "deepest condolences" to Autumn Radtke's family and friends in an announcement on its website.
Radtke's body was found Friday, Buzzfeed reported. While some news outlets in Singapore called the death a suicide, police said the investigation remains open pending the results of toxicology tests.
Bitcoin, an online currency, has been having a turbulent time. Last Friday, Mt. Gox, the largest bitcoin exchange, filed for bankruptcy protection in Japan, reporting it had lost 750,000 bitcoin or about $500 million.
Radtke's Linked In profile says she was recruited to First Meta in January 2012 by investor Douglas Abrams. She had previously worked at other startups.
"Autumn was an inspiration to all of us and she will be sorely missed," First Meta said in its announcement.
