Pulsar Group Plc has been hit with a winding-up petition from UK tax collection body HMRC.
The AIM-listed firm is behind ResponseSource, a matchmaking tool used by journalists and PR professionals, which it acquired in 2018. ResponseSource was named in a separate winding-up petition, according to CityAM.
It also operates Pulsar, an audience insights and social listening platform; Vuelio, which provides monitoring, insight, engagement and evaluation tools to more than 3,500 organisations; and Isentia, a media monitoring and insights company operating in the APAC region which is headquartered in Sydney.
Pulsar – led by CEO Joanna Arnold – told the London Stock Exchange this morning that it expects to meet outstanding VAT and PAYE obligations in due course.
