02Why we build
Avenzo was born from a simple observation: Swiss households and SMEs lose thousands of francs every year to over-paid taxes, redundant insurance and opaque fiduciary fees — because the right information is either missing or buried in cantonal complexity. Avenzo fixes that: digital, transparent, FINMA-regulated.
Make professional financial services accessible to every resident of Switzerland — not just large estates or large firms. Optimise taxes with AI, compare insurance neutrally with disclosed commissions, access fiduciary work at fixed prices.

05What drives us
Our values
- 01
Independent & transparent
As a non-tied FINMA intermediary we compare across every licensed Swiss provider — we do not sell for a single insurer. Broker commissions are disclosed, never passed to the client.
- 02
FINMA-regulated
Registered as a non-tied insurance intermediary. Every referral is made under FINMA supervision and an annual external audit.
- 03
Swiss data residency
All client data is AES-256 encrypted on Swiss servers (AWS eu-central-2, Zurich). No data is shared with foreign servers or ad networks.
- 04
Fixed pricing
Tax-return filing flat fee from CHF 89 (EINFACH / STANDARD / PREMIUM). Bookkeeping from CHF 199/month. GmbH setup from CHF 1,490. You know the price before we start.
- 05
One ecosystem
Tax filing, insurance comparison and fiduciary work under one roof — with a single shared data layer so nothing is entered twice.
- 06
Swiss fintech
Built in Steinhausen (ZG). Every flow is tuned to Swiss law, Swiss practice and the 26 cantonal systems — not a generic European stack.
