No existing bank sees the full picture of what a founder or entrepreneur has built. A company, a holding, a trust, and two or three banks each hold their own slice, their own fees, their own statement. The founder is the only person who holds the whole picture, and they must assemble it alone. Banks are fragmented by design: each institution sees only its own relationship, leaving the client to reconcile everything across providers.

Aster places the company, structures, and family on one record, served by one named banker. Two lines of business run from the same balance sheet:

• Private banking for families from CHF 5m, with mandate management, Lombard lending, and an advice layer.
• Entity banking for the professional firms (trustees, fiduciaries, independent managers, family offices) that run those structures, providing current accounts and custody for their entities.

The operating model is agentic: 47 AI agents handle onboarding, sanctions screening, payment checks, portfolio reviews, and regulatory reporting. Each file arrives drafted with sources attached. A named banker or officer then approves or rejects; the database accepts no execution without that signature. Every action is logged with who prepared it, who signed it, and on what evidence, readable by the client, the auditor, and FINMA.
