Nathan T. Hayes
Chairman, Founder and CEO
Nathan Hayes is an entrepreneur, mathematician, and software developer who has
been instrumental to the development of modal interval arithmetic and served six
years as a committee member of the IEEE 1788 Standard for Interval Arithmetic.
As one of the few in the world who knows well and can apply modal interval
arithmetic to today’s technology, Mr. Hayes has founded two companies leveraging
this arithmetic to significantly improve performances in machine learning and
At Modal Technology Corporation, he has developed ALiX, an artificial
intelligence method based on modal interval arithmetic that guarantees to find
the BEST machine training result in a single run.
At Sunfish Studio, LLC, as President and CTO, he invented the first ever modal
interval rendering systems and methods. He is the inventor of patented
applications of modal interval arithmetic in key areas of hardware design and
software method to improve the speed and quality of computer graphics.
Mr. Hayes served six years as a member of the IEEE 1788 committee for the
standardization of interval arithmetic, which became an international debate forum
concerning the future of interval arithmetic. In 2015, the IEEE committee
approved a standard
which is compatible with modal interval arithmetic.
Prior to his modal interval arithmetic years, Mr. Hayes was a software management
executive and developer at CyberOptics Corporation, a high precision sensing
technology manufacturer, for nearly a decade. Mr. Hayes has studied film production
and animation at the Minneapolis College of Art and Design, and mathematics at the
University of Minnesota.

Dr. Manny Villafana, Ph. D., S.C.
Dr. Villafana is a serial entrepreneur who never stops dreaming for himself and
for others. He was born in the Bronx, of Puerto Rican descent, and came to
Minnesota in 1967 to become Medtronic’s first international sales
administrator. From there Manny, also known as the “Cardiac Kahuna,”
moved forward to design breakthrough technology in the cardiac realm and went on
to found companies to implement these ideas.
In 1971, Dr. Villafana was the founder, chairman and CEO of Cardiac Pacemakers,
Inc., now part of Boston Scientific. Through this company he changed cardiac
history by introducing the lithium battery into pacemakers.
He then went on to found St. Jude Medical in 1976 and introduced the first
bileaflet mechanical heart valve, which reduced the frequency of blood clots in
patients. It still dominates the mechanical valve replacement market. In 2017,
St. Jude Medical was acquired by Abbott for $25 billion.
Dr. Villafana has started several other successful companies, and is now
developing his newest company, Medical 21, Inc.
