We spent hundreds of days working with world-class acoustic researches and audio engineers to create Hefio headphones


Founder and CEO

Mr. Marko Hiipakka D.Sc., Hefio’s Founder and CEO. Marko has formerly worked with spatial sound and hearing technology at Aalto University and at Oldenburg University, Germany. He holds a Ph.D. in Acoustics and Audio Signal Processing. In his thesis, Estimating pressure at the eardrum for binaural reproduction, from 2012, he developed new methods of calibrating circumaural and insert headphones for spatial sound reproduction. In addition, he has experience in marketing and sales, business relations, product management, and project management. He is an expert in Audio signal processing, Industrial 3D-design, Acoustical modeling, Hearing aid technology, IPR-­law, Industrial economics, as well as Electronics manufacturing and assembly.

Co-Founder and Board Member

Mrs. Catarina Hiipakka Ph.D. is a Marie Curie Fellow at the Department of Signal Processing and Acoustics, in Aalto University. She holds a Ph. D. in Psychoacoustics, specializing in hearing, multisensory perception, and auditory adaptation processes. In recent years, she has worked in various research projects, including topics such as the adaptation to headphone-delivered sounds, perception of sound discomfort, sound detection, and more recently sound perception by hearing­-impaired populations.

Audio Engineer

Mr. Javier Gómez Bolaños holds a Ph.D. on Acoustics and Audio Signal Processing from Aalto University. He has published several scientific articles on headphone equalization for binaural reproduction and has been lecturing on headphone acoustics at Aalto University. During his research at Aalto University, he has worked in several projects related to 3D audio over headphones. He has expertise in audio signal processing, acoustic modeling, spatial sound reproduction, and sound quality assessment.

Head of Software Development

Mr. Jari Kleimola D.Sc., Head of Software Development, has extensive experience in the software industry specializing in user interaction and real­time audio. Later he returned to academia and attained a Ph. D. from Aalto University’s Dept. of Acoustics and Audio Signal Processing on nonlinear abstract sound synthesis algorithms. His postdoc position focused on the latest web technologies and recent innovations in mobile streaming applications. During a recent research visit to the University of Padova he explored personalization support for binaural headphone reproduction in web browsers. He is expert upon a supervisor level in Audio signal processing, Realtime sound synthesis and processing algorithms, as well as in 3D audio, Software development (OSX, Windows, Android, iOS, Windows Phone), Web technologies, Distributed software architectures, Home multimedia, and Human­-computer interaction.

Senior Software Developer

Jarkko Mykkänen holds a M.Sc (Master of Science) degree in Computer Science with major in Acoustics from Helsinki University of Technology, and likes to be immersed in sound. He has a solid background in digital signal processing and embedded systems, with more than 15 years of professional experience on the subject. He has previously worked at such companies as Nokia, Airbus, Espotel and Etteplan.

Junior Hardware Engineer

Jon Fagerström is a senior year electronics student in Metropolia University of Applied Sciences. He is currently working on his bachelor’s thesis on Headphone Factory Acoustical Testing and Calibration. He has expertise in digital signal processing, acoustical measurements, electronics design and assembly.

Business Development Manager

Olga Yurbacheva holds a M.Sc. (Master of Science) degree in Economics and Business Administration from Aalto University School of Business and a CEMS Master in International Management degree. She has expertise across several business areas including business and strategic development,  key account management, international B2B sales, marketing, Russian and Eastern European consumer electronics market, international logistics and international HR. She has formerly worked at Rovio, Konecranes and Golla.
