Interactive sandwich-board pioneer Adwalker hopes to launch on AIM before the end of April with a £3m fundraising. Broker John East will act as nominated adviser and broker to Adwalker, which came to OFEX last April at 8p and is now quoted there at 12.75p, valuing the company at £14.7m. Steered by chief executive officer Simon Crisp, formerly with the Ogilvy & Mather advertising group, who brought pre-OFEX backers in at between 1.25p and 7p, the company has developed an 'interactive, mobile and wireless media platform', whose wearers are called 'Adwalkers'. They sport a flat screen on their chests, attached to a discreet, wireless-linked computer and printer, wearable around their waists. Clients, including Cathay Pacific, IBM, Sony, Unilever, Diageo, Volvo and Coors Light, use Adwalkers for advertising, interactive games, customer research, ticketing and a range of other uses. In January, the company announced a business development deal with Siemens-owned media group PS New Media, giving Adwalker exclusive access to key locations such as shopping centres and venues throughout the country. Crisp insists that 'presenting our clients with expanding opportunities to engage their target customers in highly valued locations like retail environments is vital'.
