After exposing the firm in December, Chinese authorities this week went public with the results of their rapid-fire investigation.
In televised "confessions" broadcast on CCTV, the company's top executives said that up to 95 per cent of what they sold was fake.
"Ezubo was nothing but a Ponzi scheme," said Zhang Min, a top executive.
State media reports zoomed in on the greed and guts of Ezubo's executives, noting their over-the-top salaries, love for luxury goods and their bold attempt to bury evidence, stashing "1200 documents and other pieces of evidence" in a pit. Companies such as Ezubo are supposed to be at the vanguard of China's "new normal", what the government has dubbed an era of slower, more sustainable growth as China shifts from a focus on manufacturing and investment to a service economy where innovation is key.
The company looked well-positioned because it was squarely at the centre of two sectors that the state sought to promote - financial technology and the internet.
Launched in Anhui province in 2014, Ezubo emerged at a time when people needed places to put their money. Real estate looked shaky. The stock market was wild. And it is tough, and mostly illegal, to move money overseas.

Though the nature of the ties between Ezubo and Chinese authorities are not clear, company executives certainly cultivated the impression they were "in" - and officials didn't suggest otherwise.
In February 2015, Ezubo hosted its annual meeting at the Great Hall of the People, a government building in Tiananmen Square. Ezubo was something of a state-media darling. In September, the company participated in the 12th China-Association of Southeast Asian Nations expo, a gathering focused on President Xi Jinping's "one road, one belt" initiative, an effort by Beijing to build strong economic and political ties with its Asian neighbours.
Events that linked government strategy to Ezubo's products boosted investor confidence.
Now Ezubo's has been exposed, investors want to know who is responsible.
The CCTV footage showing the "extremely difficult" excavation of Ezubo's buried records did not address the question of how the 21 people in custody managed to either dupe or pay off the legions of local, provincial and national investigators who were supposed to be keeping them in check.
