From its inception in 2004, Impedans has had a vision to put intelligent sensors on every plasma processing tool to measure what is often thought impossible i.e. the complex characteristics of the plasma state of matter used for surface modification. Impedans has experienced significant growth, year on year, since inception and has ranked highly in the Deloitte Technology Fast 50 Awards in Ireland five years running. Impedans recently secured investment from leading global venture capital firm, SOSV, to accelerate growth. SOSV specialises in multi-stage investment to develop and scale businesses.

One individual who believes strongly in the mission and vision of Impedans is Bill Liao, venture partner at SOSV and investor director at Impedans. Bill has extensive experience scaling businesses and is passionate about his non-profit endeavours with a personal mission to plant 2 trillion trees by 2020. He is the founder of WeForest, co-founder of CoderDojo and a regular guest speaker at Ted Conferences, to name but a few of his accomplishments. He became a venture capitalist with SOSV in 2011 after meeting with Sean O’Sullivan.

As a venture capitalist, Bill envisaged expanding SOSV’s European portoflio from Ireland. He describes SOSV as

The most prolific seed investor in the world, in hardware and life sciences, via our acellerators Hax, IndieBio and RebelBio.

SOSV is highly selective about its portfolio with less than 5% acceptance rate. To secure investment you need the fundamentals: a great team, great product, solid traction and scalability. Impedans demonstrated all of the above.

Bill believes Impedans will make a major impact in the Semiconductor and plasma processing industry for many reasons:

The team have amazing depth of experience, strong growth in the industry and that the products are “phenomenal”.

Impedans provide intelligent platforms for radio-frequency (RF) and plasma process monitoring. He is convinced plasma is an underutilised state of matter and that the plasma processing industry will grow rapidly over the coming years. Impedans are ideally placed to dominate the accompanying plasma measurement market.


In the last few years, Impedans global reach has expanded, gaining traction in key regions, pushing/promoting the message that plasma measurement is essential for the future of all plasma processing industries.


When asked for the secret to successfully scaling a business Bill simply replies:

It’s important to get your message out there!
