Newport Networks, which has yet to make a profit or sell any of its products, has drafted in the financial PR firm for the float.
Tavistock chairman Jeremy Carey and account manager Justin Griffiths are leading the account and report to Newport chairman John Everard.
Carey and Griffiths are tasked with promoting to investors the AIM listing of Newport, which makes session controllers – data-routing boxes that help carriers to supply and bill for voice calls made over the internet.
Griffiths said financial PR would focus on the track record of Newport’s management team, specifically Everard and non-executive chairman Sir Terry Matthews, who founded broadband equipment company Newbridge Networks, which he sold to BT in 2000 for £3.9bn.
Newport has also engaged Cardiff-based TM Communications and Media to handle technology PR.
