About Us

Modal Technology Corporation is a privately owned Minnesota corporation that offers new and proven solutions for machine learning that are based on a relatively new branch of applied mathematics known as modal interval arithmetic.

The vision of Modal Technology Corporation is to overcome well-known industry pain points which currently act as the barrier for the “Third Wave” of advancement in AI systems.

Headquartered in Minneapolis, the company is involved in the development of industry standards and works with industry partners to apply the benefits of its patented technology to many vertical markets including healthcare, finance, aerospace and defense.

Nate Hayes

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 computer graphics.

  • 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.

Manny Villafana

Dr. Manny Villafana, Ph. D., S.C.
Scientific Advisor

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.
