Hong Kong-based Japan Asia Securities has launched an online investment banking portal to help small companies raise cash. The Web site - asiapreipo.com - gives companies and investors the chance to list details of their business offers, or intended investment amounts. Users with a preliminary interest can contact the site's offline support team for investment banking services such as valuations, due diligence and documentation. Japan Asia Securities will charge 5 per cent of the amount raised from successful transactions for providing the offline services. Alternatively, users can buy financial instruments from the Web site to help them complete a transaction themselves. Tetsuo Yamashita, chief executive and founder of the firm, said the site was targetting mainly those small companies which could not afford to hire traditional investment banks. 'Most investment banks' charges are very expensive, they just do not care about small companies, even if they have a very good business idea,' Mr Yamashita said. Director Lily Yau said such a business model had already proved successful in other markets, including Singapore and the United States. Asiapreipo.com is not the only site to provide such a service in Hong Kong. DealComposer, founded by Andre Lee, the former debt capital markets financier at collapsed Peregrine Investments, provides a similar service.
