Client Update

Important update for GrowthShack GmbH

Your accounting services are getting
a stronger team behind them.

We're writing to share an exciting development in how your accounting services will be delivered going forward — with the same personal attention you're used to, now backed by significantly more capacity and expertise.

What's happening

Over the past year, Taxolution's client base has grown significantly. We've built an increasingly diverse portfolio across crypto, AI, and service-based businesses in German-speaking Switzerland, while our private tax practice in the French-speaking cantons has expanded steadily, bringing with it growing demand for accounting and business advisory services in that region too. To support this broader scope, we needed a partner with deeper capacity.

To ensure you continue receiving best-in-class service, we've partnered with DYN Group, an established fiduciary with a 40+ person team specializing in accounting, audit, and corporate advisory. Together, we've formed a new entity: DYN Advisory AG, incorporated on 12 March 2026 and based in Zug.

Ron Rosenwasser, who you know as your primary contact at Taxolution, is a co-owner of DYN Advisory AG and remains closely involved — overseeing your account, ensuring quality, and staying available whenever you need him. While different team members may handle day-to-day tasks during the initial phase, Ron is always in the loop. This isn't a handoff to strangers — it's the same trusted relationship, backed by a much stronger team.

What this means for GrowthShack GmbH

Here's how the transition benefits your business.

No more single point of failure

Your accounting is no longer dependent on one person. You gain access to a full team with backup capacity, ensuring continuity even during holidays, illness, or peak periods.

Modern accounting practices

DYN actively invests in modern accounting workflows and tooling — the same philosophy that drives Taxolution's innovation in tax services, now applied to your bookkeeping.

Same conditions, seamless transition

Your existing scope and conditions carry over to DYN Advisory AG. If you'd prefer a fresh agreement reflecting the new entity, we're happy to arrange that too.

A dedicated team for daily work

You'll be introduced to dedicated team members from DYN who will handle your day-to-day bookkeeping directly — with the same care and consistency you're used to.

Stronger corporate tax expertise

DYN's corporate tax specialists work closely with Taxolution's private tax team, giving you integrated tax planning across your company and personal finances — something that's hard to get from separate providers.
