    Is life too short to read an IPO prospectus?

    What is the purpose of an IPO prospectus? A multi-hundred page legal disclaimer, or the key information document for investors? It should be the latter, but in our experience it…


Top company executives know the feeling. It would have gone better if I knew then what I know now. Whether it’s an IPO or an acquisition, a pivot or a private placement, a presentation to the board or to shareholders, experience makes a big difference. Oakhall offers that valuable experience, the expertise that comes from decades of working as equity analysts in investment banks and in-house. Oakhall can help companies get it right the first time.

We give honest feedback and only take on projects we believe in. We aim to promote better messaging, clearer internal strategy, more efficient capital allocation, more targeted sales focus, all resulting in a more valuable business.

We work closely with your management team, board, broker, M&A banker and internal and external communications and investor relations team.

Our clients value us for our long experience and global relationships in the investment world, our understanding and analysis of their business models, market place and valuation, our willingness to roll up our sleeves and become part of the team, and the fact that we bring thought provoking solutions and a fresh point of view.

Email or call us to find out more.


We work rather like traditional management consultants: we can work on a monthly retainer, take on specific projects or offer a combination of the two. Because we work on a retainer basis, we are not conflicted by the temptation to earn higher fees by encouraging clients to raise capital or make acquisitions.

We can work in a purely advisory capacity, or hands-on within your firm in a part-time role. We would expect to meet face-to-face at at your location, and we also have meeting facilities in our Cannon Street office in the City of London.

Our service depends on an in-depth understanding of your business. We prefer to play an active part in your company and investor meetings and work closely with your management team, broker, M&A banker and PR agency. To create maximum value, we expect to be engaged for a period of six months or more.

The benefits to you are a broader pool of potential shareholders who understand your business and trust management, a better understanding of the value-drivers of your own business, choosing internal and external KPIs that actually matter, better preparation for investors’ questions and a sense-check of your strategy and management structure.
