Tiantian Kullander, the co-founder of Hong Kong-based digital asset company Amber Group, died at the age of 30 on 23 November. The unexpected death of the young crypto founder - confirmed by the company in a statement on Sunday night - has left many in the financial markets sector shocked.

“He put his heart and soul into the company, in every stage of its growth. He led by example with his intellect, generosity, humility, diligence and creativity,” the company wrote in a statement confirming his death on their website, commemorating him as a “devoted” husband and “loving” father.

“His depth of knowledge, his willingness to collaborate and his desire to always help others benefited countless start-ups and individuals. His insights and creativity inspired many projects, people and communities.

“We lost a great partner and a true friend in TT and words cannot express our sorrow at this time. TT’s legacy will live on and we will work even harder to make Amber the category-defining leader of our industry, as this was TT’s ambition and dream.”

Kullander, known affectionately as “TT,” launched Amber in 2017 with a group of financial insiders, including former Goldman Sachs Group and Morgan Stanley workers. Before that, he worked as a trader at both finance giants, and in 2019 earned a coveted spot on the Forbes 30 Under 30 list, which recognizes the most talented emerging entrepreneurs and leaders.

Besides co-founding the Hong Kong-based Amber Group, TT sat on the board of esports company Fnatic and founded KeeperDAO, a decentralized finance protocol that allows participants to trade, borrow and stake assets with protection from miner value-extracted bots, before returning it to the community.
