Alluvial revealed a swathe of leadership changes, including the appointment of a new CEO.
Mara Schmiedt, formerly the software company’s chief growth officer, is now the firm’s chief executive. Before joining Alluvial last October, Schmiedt was head of sales at Coinbase Cloud for nearly two years. She worked as a strategy manager at blockchain company ConsenSys shortly prior to that.
Alluvial also named co-founder Matt Leisinger, its former CEO, as chief product officer. Before becoming Alluvial’s CEO last year, Leisinger was a product lead at blockchain infrastructure provider Figment.
The reshuffling comes at a time when Alluvial seeks to offer more support to liquid staking protocol Liquid Collective. The protocol’s Ethereum staking went live on Coinbase Prime and Bitcoin Suisse earlier this month.
Bitcoin miner also names new chief executive
Crypto miner Bit Digital also named a new CEO in a move to go into effect on March 31.
CEO Bryan Bullett is set to step down from the chief executive post, becoming a senior adviser. Bit Digital Chief Strategy Officer Sam Tabar will fill the role.
Bullett will focus on finding additional, non-correlated income streams for the company in his new role, the company said in a press release. The New York-based company revealed last year its intention to become a validator on the Ethereum network, as well as to compile and stake ether (ETH).
“What already differentiates us is our pristine balance sheet, unleveraged and sound mining business, and exciting new Ethereum business that positions us to become a proxy for the foundational blockchain of the ‘smart contract economy,” Tabar said in a statement.
Bit Digital had roughly $33 million in cash and nearly $28 million worth of digital assets at the end of 2022 — including no debt or miner purchase obligations.
