Founded in 2015 by two scientists from Merck Pharmaceuticals — Stephen Gallagher, 47, and Alastair Hill, 42 — this Hertfordshire firm develops software to support new drug research. Its software is cloud-based, so scientists working from home continue to have full access to the company’s data and tools, which it claims can analyse a trillion strands of DNA a second. In 2018, profits reached £4.2m, with growth fuelled by funding received from Scottish Equity Partners the previous year.
