The Most Trusted Recruiting Partner
For Top Global Companies


OSI is a New York City based firm that successfully completed high-level searches throughout the world over the last 25 years.

With industry connections and research capabilities that far exceed the ones of a traditional executive search firm, we work hand-in-hand with our clients to meet their long-term objectives. Our firm has a track record of successfully delivering the best resources in the marketplace tailored to our clients’ specific needs.


Our People are the foundation for launching sophisticated horizontal / vertical search and verification processes that analyze who in the marketplace is the best technical, academic, and cultural fit.

Company is led by Steve Warren, who has spent more than 25 years working with multi-billion dollar entities to bring their vision to life. Our recruiters are handpicked from top-tier academia, such as Columbia, Duke, and NYU by our CEO. Our international recruiter base comes from United States, Europe, and Asia.


OSI prides itself in its discreet and professional approach, and being available to service our clients’ needs on their timeline.

Our goal is to isolate best-in-class candidates in the shortest time frame possible without sacrificing quality. Taking a call at 3am across the world? Typical day’s work. Advising a company on a $500M acquisition? We’ve done that, too. Our clients love us because we always deliver with a stellar level of professionalism.


For over 25 years, we have leveraged our extensive connections and knowledge base to help our clients find the right pieces to their corporate puzzle

Headquartered in midtown Manhattan, we have always been within arms reach of some of the best firms in the world and take great pride in serving them so they can continuously outperform their competitors.
