archTIS appoints new global COO

The Canberra-based tech firm has announced senior executive changes, including the appointment of a new COO, following on from its acquisition of Nucleus Cyber.

The Canberra-based tech firm has announced senior executive changes, including the appointment of a new COO, following on from its acquisition of Nucleus Cyber.

ArchTIS has appointed former Nucleus Cyber CEO Kurt Mueffelmann as its new global chief operating officer (COO) and president of its US division.


Mueffelmann will be charged with defining and overseeing the group’s overall business and growth strategy.

The new COO joins archTis’ leadership team with over 25 years of industry experience, during which he has overseen the growth and sale of five technology companies.

Mueffelmann has served as CEO of Nucleus Cyber, Cryptzone, HiSoftware (acquired by Cryptzone), Create!form International (acquired by Bottomline Technologies), and RealWord (acquired by Microsoft Great Plains).

“I am thrilled to be joining the archTIS team to accelerate growth and scale the business to meet market demand. ArchTIS provides a solution to a significant information security challenge — how allow employees and partners share and collaborate on sensitive information securely without risking data misuse, theft, or accidental sharing,” Mueffelmann said.

The firm has also appointed former Nucleus Cyber executives Irena Mroz as chief marketing officer (CMO) and Leigh Rowland as chief engineer.


Mroz joins archTis after more than 20 years of B2B software and cyber security marketing experience.  

Before joining Nucleus Cyber as vice president of marketing, Mroz held senior roles at Infocyte, Cryptzone, HiSoftware, Bottomline Technologies, and Create!form International.

Rowland will be responsible for driving the evolution of the company’s technology to provide secure collaboration and seamless integration into supported platforms.

Rowland began his career at Xerox and has since held consultant and development roles at Cyxtera, Cryptzone (acquire by Cyxtera), and Create!form International.

ArchTIS CEO Daniel Lai welcomed the new appointments, who he said would help the company achieve its growth ambitions. 

“This is an exciting time for archTIS, with a new acquisition, product capabilities and integrations. I’m delighted to welcome Kurt, Irena, and Leigh to the archTIS family,” Lai said.

“Their collective experience rounds out our executive management team and brings a new level energy to the business.”

He added: “With their combined leadership, marketing, and product development skills, we are strongly positioned to rapidly expand our growth and customer base.”
