Why Pillar 5

Switzerland's pension system rests on three statutory pillars and a fourth, private one. Together they cover traditional provision.

Pillar 5 stands for what lies beyond: the value inside your company, in its processes, its data and its digital assets.

That is where we start: with advice, our own team for delivery, and coordinated specialist partners for the rest. Decisions stay with you.

Pillars 1-4 · your company as pillar 5

Services

Advisory

Strategy

For decisions that affect the whole company: prepared with you, and carried through in a mandate if needed.

Direction · Capital · Succession · Governance

AI in daily operations

We start with the task that costs you time or nerves, and use AI only where it clearly makes the work easier.

Digital Assets

For holdings that do not fit the classic balance sheet.

Structure · Self-custody · Governance

Project Delivery

Our own team delivers most of it; we coordinate specialist partners for the rest. Access, data and know-how stay with you.

Pillar 5 does not provide investment advice or asset management with power of disposal over third-party assets under FinSA/FinIA. Information on real-estate projects or specialist-partner services is not a binding offer. Digital assets can be subject to substantial value fluctuations. No third-party custody without a separate agreement. Further information: Legal Notice.
