Medici Ventures is a blockchain-focused venture arm founded in 2014 as a wholly owned subsidiary of Overstock.com (now Beyond, Inc.). Unlike traditional venture funds, Medici operated as a corporate venture vehicle rather than an independent fund, meaning it did not raise capital from outside limited partners. Its assets under management were never publicly disclosed as a standalone figure. The firm set out to apply blockchain technology across a wide range of industries – including financial markets, land registry, agriculture, and voting – at a time when most institutional capital still dismissed the space.
The firm's investment thesis was shaped largely by Overstock founder Patrick Byrne, who became one of the most outspoken corporate executives advocating for blockchain adoption in the mid-2010s. Medici backed companies using distributed ledger technology to replace or improve legacy infrastructure, with particular interest in emerging markets where traditional systems are weak. Geographic targets included the United States, Latin America, the Caribbean, and sub-Saharan Africa.
Notable investments
- tZERO – Medici's flagship bet. A blockchain-based alternative trading system (ATS) built to tokenize securities. tZERO raised roughly $134 million through a security token offering in 2018, one of the largest STOs of its era. It operated under SEC and FINRA oversight. tzero.com
- Medici Land Governance (MLG) – A spinout focused on blockchain-based land titling in developing countries, with pilots in Zambia, Rwanda, and other African nations.
- Bitt – A Caribbean fintech company working on digital currency infrastructure. Bitt later partnered with the Eastern Caribbean Central Bank on a central bank digital currency (CBDC) pilot.
- Ripio – A Latin American crypto and fintech platform serving Argentina, Brazil, and Mexico. One of the region's earlier institutional-backed crypto companies.
- GrainChain – Agricultural supply chain platform using blockchain to connect farmers, buyers, and lenders. Focused on Latin America.

- Symbiont – Enterprise blockchain infrastructure targeting financial markets and institutional data management.
- SettleMint – A blockchain middleware platform aimed at enterprise developers.
Team
Patrick Byrne, Overstock's founder, was the driving force behind Medici Ventures from its inception. He stepped down as Overstock CEO in August 2019 following public statements he made about being a government informant and his admitted relationship with Maria Butina, a Russian national convicted of acting as an unregistered foreign agent. His resignation triggered a sharp sell-off in Overstock's stock. Jonathan Johnson, a longtime Overstock board member and executive, subsequently led the parent company and oversaw Medici's portfolio. Public information about dedicated Medici Ventures managing partners beyond these figures is limited.
Recent activity
Medici Ventures significantly restructured between 2021 and 2023. Overstock, refocusing on its e-commerce home goods business, moved to consolidate or wind down several of Medici's peripheral portfolio companies. tZERO remained the most actively developed asset. Bitt's CBDC work with the Eastern Caribbean Central Bank drew continued attention as governments explored digital currencies. Several of the smaller portfolio companies – particularly those in early-stage blockchain infrastructure – faced difficulty as crypto market conditions deteriorated through 2022.
Medici Ventures' legacy is mixed but historically significant. It was one of the earliest corporate venture programs to commit seriously to blockchain across multiple verticals before the 2017 bull run. tZERO remains an active regulated trading platform. However, several portfolio bets – including Voatz and some enterprise blockchain plays – did not deliver the outcomes initially projected. The program stands as an early case study in both the promise and limits of corporate blockchain venture investing.
