Capital Introduction

We view capital introduction as a serious reputational commitment and approach the effort with the thoroughness and seriousness investment managers, and those investing with them, should expect. Why are we different? Essentially, because we think like investors. Key members of our management and consulting teams have experience managing hedge funds, investing with hedge fund managers over long periods of time, serving firms that allocate to hedge funds and marketing for discreet funds.

This experience, a critical differentiator in the industry, directly influences the way we assess, analyze and compare performance and the risks managers assume to generate such returns. Our approach allows us to be helpful to our hedge fund clients as we assist them to better understand their performance and that of other managers engaging in similar strategies. It also allows us to be helpful to investors, as we engage in a rigorous analytical process not unlike many allocators undertake themselves prior to making investments.

Targeted Introductions

Our team maintains a regular dialog with the firm’s allocator contacts and works to gain insights about their experience with managers and the needs they need to fill. Armed with such information, we set out to search for managers whose strategies and return profiles match these needs from among the managers in our database, and arrange for one-on-one meetings. As part of our effort, we regularly host investor meetings at which managers have an opportunity to discuss their investment strategies and return profiles, and respond to inquiries from allocators.

Benefits to Both Managers And Allocators

We work to gain a clear understanding of our clients’ investment strategies, goals and objectives, which allows us to conduct a consultative approach to capital development. This includes providing assistance in assessing our clients’ performance against comparable strategies, reviewing and providing constructive critique of their marketing materials, preparing them for investor meetings and opining on their overall marketing strategy. We also leverage the information flow our team acquires through our relationships with hundreds of hedge fund investors who invest with emerging managers and share that knowledge with our clients as we consult about introductions.

This process has allowed us to develop solid relationships among a wide range of investors who typically invest with emerging as well as more seasoned hedge fund managers. The allocators have come to appreciate the thoroughness of our work and the targeted approach we take in making introductions – only when we have good reason to believe there is interest. When we suggest a new idea, they know it’s something that likely matches one of their mandates. Our focused approach also means that managers can be assured that when we make an introduction, it’s done so with the understanding that their investment strategy is of interest to the allocator.

We are uniquely positioned as we serve a large number of managers through the prime brokerage and outsourced trading businesses allowing us a great degree of transparency into their performance and risk characteristics. We are also able to review a large number of emerging and established managers on a regular basis when they are introduced by our prime brokerage and outsourced trading business development teams or seek us out to potentially provide specific services.

New Launch Consulting

Our prime brokerage sales group has always functioned in a consulting capacity, helping managers to understand what’s involved in launching a fund and managing its growth. This is perhaps the most important service we can provide as it sets an appropriate expectation level with prospective clients. It also allows us to showcase our extensive knowledge of the hedge fund space and the comprehensive range of services we can offer clients. We have developed pre-launch “how to” booklets and spread sheets that managers find particularly helpful. We have helped hundreds of managers successfully launch new funds over the years, and remain available throughout the relationship to provide advice on growth options, new hires, seed investor opportunities, and other such issues that arise.
