Jacek Kuropatwinski

Co-Founder & CEO of DesignedBuilt Europe Sp. z o.o.

Jacek is an entrepreneur with strong record of successes and failures that gives him the strength to overcome any obstacles and adversities.

Prior to co-founding DesignedBuilt Jacek spent almost two decades in real-estate development and construction business, including the last seven years in the high-end residential market in NYC.

After spending years working along side on-site construction workers, Jacek has identified off-site construction as a way not only to improve efficiency and quality, but importantly, as a way to improve life quality of construction workers.

Jacek believes that ethics and social responsibility are very important in life and business.  As co-founder of a school and supporter of educational projects for kids and youth, Jacek is happy giving back what he was so lucky to receive.

In our production facility in Poland Jacek is dedicated to implement best available technology in home design and fabrication with full respect to environment and sustainable development.

Jacek's goal is to create the best place to work in entire construction industry.

Jacek lives in Gdansk Poland and regularly travels to the United States.
