2026

Researcher and Investor

Aalto University
In addition to exploring a backlog of ideas and projects, I'm working on finishing my PhD (at Aalto) and doing some minor investments here and there.
2025
With NL Acoustics fully integrated into the new owner's organization, it felt like the right time to close this chapter and look toward new horizons.
2022
We gained interest from Teledyne, which made a majority investment in 2022. I continued as CEO, guiding the company through sustained growth and strong profitability for the next three years.
2015

CEO and Co-Founder

NL Acoustics 2015-2025
We founded NL Acoustics, a B2B hardware and software company making acoustic cameras, in 2015. Early on I worked on a wide variety of hands-on tasks around the product, development and sales. As we grew, I shifted from hands-on work on the product to building a compact organization of about 50 people, and keeping clarity on the direction of the company.
2014

Doctoral Candidate

Aalto University
I worked part-time on modeling acoustic responses as constrained optimization problems, but the growing momentum of NL Acoustics eventually demanded my full focus.
2013
First discussions with Jonas. Why should you need a PhD to use acoustic cameras, something that could be accessible to anyone? That meeting sparked NL Acoustics.
2012

Founder

Kaistale 2012-2015
I started freelancing in software and acoustic consulting - both to pay the bills and to fund early work on Noiseless Acoustics (later renamed NL Acoustics). It taught me a lot about the basics (and challenges) of running a business.

First role in acoustics, focused on consulting, design, and standardized acoustic measurements.

MSc in Acoustics and Structural Mechanics

Aalto University
I graduated in 2012 with an MSc in Acoustics and Structural Mechanics.
2008

Software Developer

Lemminkäinen 2007-2012
I built a custom CMS that was eventually rolled out to 100+ construction sites internationally. Later on, managing this system brought some of the first revenue for my early entrepreneurship career.
2008

Site Engineer

2007

Quality Engineer (Trainee)

Lemminkäinen 2007-2012
I consider this my first "real job" relevant to my career. Before this job, I'd worked in convenience stores, a hamburger joint, a biomedical research institute, and as a substitute teacher.
