OneVentures has been absolutely foundational to our success.
It’s not just bringing money to the table. It’s bringing support, emotional support, strategic support, and a team of people who stand behind the brand. And, without OneVentures, I don’t think we’d be where we are today.
David Hoey
Strategic Advisor, Founding CEO, Vaxxas
OneVentures has been terrific to work with as a lead investor, but it’s what they add in addition to investment that has been critical to Vaxxas’ growth.
Working with the OneVentures team has translated into sharpening all aspects of our development and commercialisation strategy and actively helped us forge connections and partners with industry.

From day one, OneVentures really rolled up their sleeves and became true partners in the business. They brought a mix of strategic insight, operational know-how, and a strong network that helped us make some big decisions early on, from restructuring to scaling for growth. It always felt like they were in our corner, and it’s been a great partnership all the way through.

OneVentures’ contribution to ImmVirX has extended well beyond capital. I would recommend them to any life sciences company looking for an investor that brings real sector expertise and a genuine willingness to contribute over the long term.
