Maven has a strong track record of backing life science businesses such as BioAscent, another CRO, which has performed very strongly since the Maven VCTs invested in 2018. I am very much looking forward to working with Andy and his team and to drawing on Maven’s experience with similar life science businesses and many other SMEs to help scale this exciting business.”
