Thanks to its award-winning virtual radio studio technology, the start-up, founded in 2018, already counts some prestigious European broadcasters among its customers and is looking at reaching more on its global market. The company also just announced a new solution for automating any workflow involving sound, reinforcing its position as the virtual audio specialist in the media industry.

The investment will be key in the ability for the company to reach more and more broadcasters and accompany them in their transition from hardware-intensive facilities to flexible and scalable virtualised infrastructures.

Originally a member of the imec.istart program (now an alumnus), On-Hertz could count on the extended support of the no.1 university-linked accelerator in Europe (source: UBI Global). Reserved to a few selected projects, imec.istart Fund shows its confidence in the venture and further expands its stake in On-Hertz. imec.istart Program Manager Sven De Cleyn states: "The traction of On-Hertz's virtual radio studio proofs it's tapping into a real need for the rapidly evolving media sector. We are very happy to offer further funding and support for the international expansion of our program alumnus On-Hertz."

Sambrinvest, one of the financial partners of choice for SMEs in Wallonia, with more than 200 companies in its portfolio, becomes the largest shareholder next to the founders.

“Investing in a Company such as On Hertz perfectly fits with Sambrinvest's digital strategy of creating jobs and helping companies to become "global champions" in their sector. We believe that the software developed by Renaud & Benjamin is totally disruptive and will answer to the real needs of the broadcasters” says Flavia Pati, Investement Manager at Sambrinvest.

Finally, On-Hertz is joining the portfolio of innovative Belgian start-ups that are supported by Seeder Fund and will benefit from their extensive experience as fund managers. “Seeder Fund’s team has been very impressed by the vision of Benjamin and Renaud and their drive to create long lasting impact on the broadcast industry. Their mastering of the needs and constraints of their target customers and their ability to provide them with a performing solution led them to already qualify as a trusted partner of key broadcasters on multiple geographies. We are thus very happy to support On-Hertz in its journey to become a global leader in the digitalisation of the broadcast market and make our resources and expertise at their disposal to achieve its goal” says Pierre-François Hellebuyck, venture capital at Seeder Fund.

“As entrepreneurs aiming to bring On-Hertz to the next level(s), we are extremely satisfied to have raised smart money with these three partners. We are not only getting financial associates onboard, but experts in digital start-ups doubled with renowned technical partners”

says Benjamin Lardinoit, co-founder On-Hertz.

“Our technology already started to transform the way broadcasters envision their workflow. This round gives us extra wings to do it at a much bigger scale”

adds Renaud Schoonbroodt, co-founder On-Hertz.
