Xfive’s team rental model helped me easily acquire a new team member for our project. Marek has been working with us for many months and although he is an external contractor, I feel like he's a part of our family now.

Our story

Dave Rosen and Stan Dzavoronok

Foundation of the company

Dave Rosen and Stan Dzavoronok had an idea of a business for converting PSD to HTML. It worked out and their company, XHTMLized, not only grew fast but was copied by multiple other companies.

The first version of Twitter

Cooperation with world-leading brands

During its early years XHTMLized worked as a web development partner for companies like Twitter, eBay, Fox, and Rogers. We were the ones who coded Twitter’s first UI!

X-Company meeting in Krakow, Poland

The "X-Culture"

As a result of the company’s success, Dave and his team established several new brands that specialized in different parts of web development. They were connected by “X-Culture” which encouraged talented people to unleash their inner heroes.

The small part of Australia in Poland

XHTMLized was the only brand within the X-Company that set a physical office a few years earlier. In the fall of 2014 we’ve moved to the new, modern space in the heart of Krakow, Poland, creating a small piece of Australia in Europe.

Xfive's operational team in 2017

Rebranding to Xfive

Chasing our own identity and supporting the unceasing changes on the market, we dropped the old brand and became Xfive. The new name’s origins were within the internal culture of “fives”, that spread across the relationships with our clients that we truly care about.

New brand identity and goals

Now a fully matured company, Xfive hires over 50 people and is present in Melbourne, San Francisco and Krakow. The new brand identity reflects the change in our offer and the way we work. We have grown up, and became a software-house that can handle design and development of a complex web and mobile applications.
