24Haymarket backed the environmental monitoring firm to help scale its commercial operations and product innovation.
"WATR is delivering critical infrastructure and real-time data solutions at a time when environmental monitoring is a global priority. The team’s technical agility and deep sector understanding position them to be a leading player in this fast-growing space."
The funding round was led by 24Haymarket with participation from Foresight Group.
"Previsico’s flood forecasting technology provides users with early warnings to take preventative action to reduce damage and losses from flood water. The value proposition to its customers stretches beyond loss mitigation and importantly reduces the negative social impact of flooding. We are thrilled to support Previsico’s CEO Jonathan Jackson and his wider team on this exciting journey."
The investment round was led by 24Haymarket with participation from angel investors and Innovate UK.
"We’re delighted to announce Lori as the new Chair of our Board. The wealth of her strategic experience in the digital space coupled with her sales expertise and commitment to diversity and inclusion, will support myGwork’s ambitious international growth targets,"
The seed round was led by 24Haymarket with participation from Oxford Innovation EIS Growth Fund 2 to support commercial scale-up.
"Our continued research and innovative work has resulted in a coloured carbon fibre composite that is light and strong, without compromise, pushing the boundaries of design and technology."
The pre-series A round was led by 24Haymarket with backing from Northstar Ventures, UKRI, and Dhiraj Mukherjee.
"Whilst most companies have some form of volunteering or a social good program, typically engagement is really low. We solve that by making doing good bite-size, on-demand and based on your exact location with off-the-charts employee engagement results. That’s because the world wants to do good: we’ve just made it so much easier. This raise lets us help businesses everywhere deliver incredible impact."
