Sebastien Borget is a French entrepreneur and angel investor best known as the Co-Founder and Chief Operating Officer of The Sandbox, one of the leading blockchain-based virtual worlds built on Ethereum. He is widely recognized as a prominent voice in Web3 gaming, the metaverse, and NFT-based digital ownership. His angel investing activity reflects his deep roots in this space, with a reported portfolio of nine projects concentrated in blockchain gaming, NFT infrastructure, and decentralized entertainment.
Borget began his career in mobile gaming. He co-founded Pixowl alongside Arthur Madrid, the studio behind the original The Sandbox mobile game. In 2018, Animoca Brands acquired Pixowl and backed the pivot of The Sandbox into a blockchain-based virtual world. Under Borget's operational leadership, The Sandbox grew into one of the most recognized metaverse platforms globally, selling virtual land parcels as NFTs and partnering with brands including Adidas, Gucci, Warner Music Group, and Snoop Dogg. The project raised a $93 million Series B round in November 2021, with SoftBank Vision Fund 2 among the lead investors.
Borget has been an active public advocate for digital land ownership and player-owned economies. He speaks regularly at major industry events including NFT.NYC, Token2049, and Davos side events. His public profile has made him a sought-after angel investor for early-stage Web3 gaming and metaverse projects seeking both capital and strategic visibility.
Notable investments
Public information about the specific composition of Borget's nine-project angel portfolio is limited. Based on publicly available information and his stated areas of focus, his investments are concentrated in:
- Web3 gaming studios – early-stage teams building play-and-earn or player-owned game economies on EVM-compatible chains
- NFT tooling and infrastructure – platforms that support digital asset creation, trading, and royalty management
- Metaverse adjacent projects – virtual world layers, avatar interoperability, and social experiences built on blockchain
No individual deal sizes have been disclosed publicly. Borget has not announced a formal fund or vehicle; his investing appears to be personal angel activity conducted alongside his operational role at The Sandbox.
Team
Borget operates as a solo angel investor. His primary professional affiliation remains The Sandbox, where he leads operations and partnerships. His co-founder at The Sandbox, Arthur Madrid, serves as CEO. Both Madrid and Borget have backgrounds in mobile gaming through Pixowl. Animoca Brands Chairman Yat Siu is a closely associated figure given Animoca's ownership stake in The Sandbox and its own extensive Web3 gaming portfolio.
Recent activity
Through 2024 and into 2025, Borget remained active in the industry during a broader cooling of metaverse valuations. The Sandbox faced headwinds shared across virtual world platforms as speculative NFT land prices declined from their 2021–2022 peaks. Borget responded publicly by emphasizing long-term builder communities over short-term speculation, and The Sandbox continued releasing new game experiences and brand partnerships on its platform. His public commentary on X (formerly Twitter) reflects ongoing engagement with Web3 gaming founders and policy discussions around digital asset regulation in the United States and Europe. He has also participated in discussions around the EU's MiCA regulatory framework and its implications for NFT markets.
Borget's investment thesis centers on the long-term shift toward user-owned digital economies. His value to portfolio companies is primarily strategic – brand association with The Sandbox, access to its partner network, and visibility within the metaverse community. Investors or founders seeking context on his specific deals should consult his Crunchbase profile, as deal-level disclosures remain sparse in public filings. Given the current Web3 gaming cycle, his portfolio likely faces a mixed recovery path, with projects that built genuine player communities faring better than those that relied on speculative NFT demand.
