Chateaushi AG, a tech platform focused on historic real estate financing and preservation, today announced the launch of its public token sale for CASL.

After four years of development, Chateaushi has evolved into a decentralized marketplace designed to support the funding, management, and commercial use of historic estates across Europe.

“We’re excited to open our token sale to the public and bring our vision for democratizing historic real estate to a broader community,” said Brittany Kaiser, co-founder and co-CEO of Chateaushi. “This represents a milestone in our journey to transform how historic landmarks are financed, preserved, and experienced.”

The platform connects estate owners, investors, and users through a shared ecosystem that offers token-based access to luxury stays, private events, and investment opportunities.

CASL token powers bookings, access, and investment. The utility token enables bookings at 100+ historic estates, entry into private members clubs, and payments via the upcoming Chateaushi card. It also unlocks real estate consulting, brokerage services, and a fractional investment marketplace.

The token pre-sale begins Tuesday, May 13. Participants can register at chateaushi.com for full details.

The platform also includes Helix, an AI concierge for planning travel experiences, and has secured partnerships with over 100 estates as well as premium brands like Krug Champagne and the FEDORA cultural network.
