Nominated Advisor (NOMAD) is a type of financial services firm acting as an intermediary for companies wanting to list their stocks on the London Stock Exchange's Alternative Investment Market (AIM). In most cases, these firms come in the form of boutique investment banks. The role of the NOMAD is to assist companies in meeting the stringent criteria required by the LSE with respect to listing requirements, as well as to provide continual market oversight after the company has been successfully listed.

The NOMAD must have experience in the field of mergers and acquisitions, corporate finance, corporate broking and equity research – this is necessary in order to advise and guide companies through the sometimes lengthy listing process. These advisors must also have sufficient resources and breadth of knowledge to effectively meet the unique requirements of companies aiming to list on the AIM. Furthermore, the NOMAD must demonstrate the financial expertise necessary to evaluate the prospects of the business, and assess any financial risks associated with the listing.

Once a company has been successfully listed, the NOMAD must provide frequent advice and monitoring services to ensure the company remains within a healthy financial standing. The role is much like that of a fiduciary, as NOMADs must maintain strong relations with the LSE and other authorities related to the listing of companies. They must also remain actively engaged in the daily dealings of the listed company, providing guidance on the development and implementation of strategic plans, as well as providing advice on how to best promote the company's stock.

Ultimately, the NOMAD serves to shepherd companies through the complex regulations and requirements necessary to successfully list on the AIM. As such, the NOMAD must have considerable knowledge and experience in the field of corporate finance and capital markets in order to successfully fulfill their role. By doing so, they are providing companies an invaluable service in helping them unlock the true potential of their business.
