About Copycat Websites and Fraudulent Activity

A Personal Message from Thomas Züllich

Over the past months I have been made aware that several copycat websites and email senders have begun using my name, my initials (“TZ”), and variations of the TZ Audio brand in attempts to mislead people—especially content creators and small businesses.

These actors have no connection to me or to TZ Audio in Norway.
They use similar-looking domain names, offer unrealistic “collaboration deals,” and in some cases ask people to purchase products upfront in exchange for promises that are never fulfilled.

I want to be absolutely clear:

I, Thomas Züllich, operate only one business: TZ Audio (formerly Rational Acoustics Scandinavia).

My official website is: https://www.tzaudio.no

I do not run or endorse any of the following types of activity:

  • So-called “free microphone” promotions that require you to buy something first
  • Unsolicited influencer collaborations or review-for-payment schemes
  • Websites with domain names similar to mine but not tzaudio.no

If you have received an email, offer, or message that seems suspicious, please do not engage with it.
These operations are unfortunately part of a broader pattern of fraudulent online behaviour targeting creators and consumers worldwide.

If you are ever in doubt — contact me directly

I take the integrity of my work and the trust of my customers very seriously.
If you are unsure whether a message truly comes from me, or if you simply want to verify something related to TZ Audio, I invite you to contact me personally:

📞 Direct phone: +47 971 23 033
💬 Zoom call: Happy to schedule one on short notice
📧 Email: zullich@me.com

If it doesn’t come from one of these channels or from zullich@me.com, it isn’t me.

A small business built on personal trust

TZ Audio is a small, specialised operation offering professional audio solutions, training, and consultation.
I’ve always worked transparently, personally, and directly with clients — and that will not change.

Thank you to everyone who has reached out, reported suspicious activity, or simply taken the time to verify things with me.
Your vigilance helps protect not only my business, but everyone in our community.

If you have questions, concerns, or simply want to talk audio — don’t hesitate to get in touch.

Warm regards,
Thomas Züllich
