Have you ever imagined a world where historic castles are not only silent witnesses to the past but also future investment opportunities?

At the Founders Room event organized by AllSpark Research, Brittany Kaiser, CEO of Chateaushi, explained how her company connects blockchain technology with cultural preservation, opens up investment access to the public, and creates new opportunities in the previously hard-to-reach historic real estate market.

What Inspired the Creation of Chateaushi?
Brittany Kaiser is the figure behind the founding of Chateaushi. In her career, she became known as the Cambridge Analytica Facebook whistleblower. She decided to leave big tech and fully transition to crypto in 2017 because she wanted to build technology with a decentralized architecture.
The name “Chateaushi” was chosen from the idea of a blockchain launch party in a French château. From there, Kaiser began imagining a project to connect blockchain with castles, archaeology, and historic buildings. In 2021, she was able to realize this in Europe through security tokens.
What Makes Chateaushi Different from Other Web3 Projects?
Chateaushi stands at the intersection of blockchain, culture, and historic property. Unlike most Web3 projects that focus solely on financial gain, Chateaushi offers a Marketplace Real-World Assets (RWA) business model specifically for historic properties. Much like Airbnb, this model allows owners to list rooms, events, or tours for rent. Owners can also tokenize future access or equity. Meanwhile, users can book stays or events or buy access rights through tokens. The proceeds from token pre-sales can be used to fund the restoration of historic sites.
What Problem Does Chateaushi Aim to Solve?
The global historic real estate market is valued at over $4 trillion but has traditionally been accessible only to elite investors. People in the crypto industry often rent castles for events at high prices, or even buy castles, but then struggle to maintain them.
On the other hand, many historic buildings, especially in Europe, are deteriorating due to a lack of sustainable funding. Many families inherit castles but do not have enough money for maintenance. Based on this, Chateaushi aims to bridge the gap between estate owners and renters or investors. Chateaushi wants to create a sustainable funding system for the preservation of cultural heritage while making historic assets more accessible to ordinary people.
What Innovation Does Chateaushi Introduce?
Chateaushi officially launched the public sale of the $CASL token on May 13, 2025. The $CASL token has utilities that include opportunities for fractional ownership, access to VIP events, and discounted bookings at luxury historic properties. $CASL tokens can be purchased on chateaushi.com via Sovryn’s Origins platform and can be paid for with almost any major token.
The token sale is structured in multiple rounds with tiered pricing, including bonus incentives for certain payment methods and a referral program. This strategy has successfully attracted strong community interest. In addition, Chateaushi has introduced the concept of a Private Members Club. This concept consists of two parts: membership tiers and the Private Members Club network.
What Are Its Main Achievements and Future Plans?
Currently, Chateaushi is completing token distribution and preparing for a public listing on an exchange. Their target is not for a few wealthy individuals to buy many tokens but for many people to buy $50–$100 worth of tokens, fund projects together, and enjoy the benefits.
The chateaushi.com website already features 40 historic properties ready to be booked, with over 100 castles already under contract and 800 more in the due diligence queue. These properties are owned by a variety of parties, from private families to foundations and government institutions, many of which are only available for exclusive rental through the Chateaushi platform, offering privileged access not found elsewhere.
Chateaushi will also create its own private club in Paris by tokenizing a historic five-story building on the banks of the Seine River, where security tokens will be used to finance the purchase in a cash-flow-positive commercial real estate model. Members will be able to stay in the building’s apartments and attend various events such as parties, workshops, and gatherings, while the issued security tokens will be dividend-bearing, much like shares that provide profit-sharing to holders. Going forward, Chateaushi will continue to develop its marketplace and property portfolio.
