The recruitment platform has raised funding managed by Mercia to support its expansion into the US market.

"Remote working means developers are no longer limited to one location. Haystack offers a ‘safe space’ where our community can research the different opportunities without being bombarded by calls from recruiters. Feedback from our multinational clients shows there is an opportunity to offer the same service in other countries. This new investment will enable us to target the US initially with a view to moving into Europe at a later stage."

The seed round was led by IQ Capital with participation from several specialist energy and deep-tech investors.

"Working through a pandemic, scaling what was just an idea to fully functioning devices in less than three years, shows not only our team’s skill and dedication but the conviction of our network that IONATE is a key technology for the energy transition. With visionary experts from deep-tech venture capital, the utility sector, and academia in this round, we could not have chosen more strategic partners for achieving IONATE’s huge potential. I’m very excited for the next chapter and to work side-by-side with our investors and partners on what promises to be a time of extraordinary development and growth."
— Matthew Williams, Founder and CEO
