An AI-driven technology solution to help optimise video quality whilst reducing bandwidth for streaming

iSIZE has built an artificial intelligence (AI) video technology that optimises video quality while substantially reducing the size and bandwidth required to stream. This makes streaming quicker, cheaper and less environmentally damaging by reducing its carbon footprint. 

The demand for video streaming, and the cost, has been growing globally for years. The coronavirus pandemic saw demand for streaming grow even faster. Video is expected to represent 80%1 of the global internet traffic by 2022, so there’s a substantial need to be able to transmit video more efficiently, without compromising quality.

Why we like it

iSIZE has secured a partnership with Intel and has licenced its solution to top tier tech companies. It’s rare for deep-tech companies at this stage to have generated this level of commercial engagement. Beyond these big tech companies, the technology is also suitable for video on demand, live streaming, gaming, social media and more. The video streaming market was valued at $40 billion in 2019 by revenues and is anticipated to reach approximately $180 billion by 20271, with live streaming accounting for the largest revenue share. iSIZE’s ambition is “to be to video what Dolby is to sound”. The scale of this ambition matches our mission to help pioneers build world-changing companies. 

This early progress is testament to the team’s exceptional drive, execution capability, and the superiority of the technology they have engineered, a view shared by existing advisers and mentors of the business. The founding team are seasoned technologists with deep expertise in the video streaming and machine learning space.

What our fund managers say

“Video streaming is exploding – even more people are home streaming through video platforms. This is also central to robotics, drones and autonomous vehicle industries, which are evolving rapidly. iSIZE has a valuable solution essential to these industries, something major players are already recognising.”

Risks to bear in mind

Capital at risk

The value of an investment can fall as well as rise. Investors could end up getting back less than they put in.


Shares in EIS-qualifying companies could fall or rise in value more than other shares listed on the main market of the London Stock Exchange.


We will be investing into shares in unlisted early stage companies. These shares will be harder to sell than established listed companies. Investors should expect to hold shares for between five and ten years, and possibly longer.

Tax treatment and qualification

Tax treatment depends on individual circumstances and may change in the future. Tax reliefs depend on the portfolio companies maintaining their EIS-qualifying status.
