Strategy
Direction, capital allocation, succession, and governance for owner-managed firms; bank, trustee, and advisor alignment inside the mandate; clear decision paths before structure and delivery.
Pillar5 GmbH · Basel-Stadt
For owner-managed and mid-size companies, entrepreneurs, and families in Switzerland. Advisory and delivery under one mandate; coordinated with your tax, legal, and financial advisors.
Beyond traditional wealth.
In Switzerland, provision rests on three statutory pillars, with private savings as the fourth. Pillar5 is the fifth layer when strategy, assets, and operating reality outgrow that frame. Inside the mandate we keep the picture clear and the handover written down; decisions stay with you.
How we work
Advisory and delivery; one point of contact; scope agreed in writing.
Direction, capital allocation, succession, and governance for owner-managed firms; bank, trustee, and advisor alignment inside the mandate; clear decision paths before structure and delivery.
Inside the mandate we identify which workflows fit AI, train your team on the tools you keep, and automate only what you approve.
Orientation, setup, and ongoing support: self-custody and hardware wallets (e.g. Ledger), documentation within the mandate, and someone to ask. No third-party custody without a separate agreement.
Digital presence, structure and real estate, design, BIM, analytics, automation, and fundraising; in-house and with specialist partners. One contact; coherent scope and handover.
Delivered by Pillar5.

Advisory is provided on a mandate or fixed-fee basis. No investment advice or asset management with dispositive power over third-party assets under FinSA/FinIA.
