About Iris

IRIS Audio Technologies is a cutting-edge audio technology company with a mission to enable the world to Listen Well.

Its suite of patented products leverages decades of research into the effects of sound on the brain, prioritising focus, productivity, and wellness for all. By harnessing the science of sound, IRIS dramatically improves how people experience audio across all digital platforms, from video meetings to streaming, podcasts to audiobooks.

Its flagship product, IRIS Clarity, uses the most advanced AI to remove background noise from calls, shortening Average Handling Time (AHT) by up to 11%, reducing sound-proofing costs by more than 50%, eliminating noise-related complaints from both customers and agents by 98%, and improving transcription accuracy — and thereby speech analytics — by more than 10%. The UK-headquartered company will use the investment to drive adoption of its IRIS Clarity solution globally and, in particular, North America, where it sees a huge opportunity.


The company’s view

“As organisations from public services to motor racing and call centres become ever more virtual in how they communicate, our mission is to make critical communications clearer, more effective and less taxing by eradicating background noise. We want to help contact centre staff deliver more resolutions and motorsports teams win more races through higher quality digital communications. This funding round is a significant step in enabling that.”

Jacobi Anstruther, Founder & CEO at IRIS Audio Technologies

Our view

“We’re hugely excited to be partnering with IRIS Audio Technologies, a business that we believe has huge capacity to scale. IRIS Audio’s unique technology has already proven to have demonstrable benefits to the contact centres it serves and the breadth of use cases for its technology gives it a significant addressable market. The company benefits from a truly exceptional leadership team, and we’re excited to be part of the journey.”
