It actively utilizes digital technologies including AI to develop and provide "ALTERNA," an asset management platform for individual investors. To date, it has provided a cumulative total of 19 funds (the highest number domestically) - 5 through external securities companies, 13 through its own "ALTERNA" service, and this project as the 19th.
Daiwa Securities

Progmat
Progmat provides "Progmat SaaS" to ALTERNA Trust, MDM, and Daiwa Securities, supporting smooth business operations. "Progmat SaaS" is a product that enables a wide range of financial institutions to easily start digital asset-related businesses (registry management, custody, etc.) without building blockchain/distributed ledger nodes on their own servers, and also enables a wide range of securities companies/intermediaries to complete private key management for investors in-house without delegating to third parties (custodians). By providing this product, it contributes to reducing scheme costs and maximizing yields returned to investors.
Moving forward, the partners will continue to create diverse fundraising methods through cross-industry collaboration and provide further investment opportunities to investors.
