Amplifying Value In The
Marketer-Agency Ecosystem


Hasan + Shumaker was born from the belief that in the marketer/agency ecosystem, it is essential to have transparency and a mutual appreciation of and respect for one another’s requirements in order to have a sustainable partnership that generates value.

Hasan Ramusevic has led marketers through the agency review and selection process since 1989, making him the longest-tenured active consultant in the field.

With that experience comes an acute understanding of marketer-side needs and a nuanced approach to guiding agencies toward solutions. Both have contributed to the formation of hundreds of successful client-agency partnerships, with many lasting over 10 years.


Over the same timespan, Chris Shumaker has overseen successful client-agency partnerships while leading growth and business development at some of the world’s most recognized agencies. With that comes a keen sense for custom-tailoring agency teams and disciplines to solve client-side challenges, coupled with a deep appreciation for what agencies need from clients in order for both parties to be successful.

Hasan + Shumaker brings together marketer and agency perspectives in the pursuit of a balanced approach to solutions to restore, create, and sustain harmony in the marketer/agency ecosystem.

It’s Not Agency Search. It’s Agency Fitting.

While we do run a tight, professional, and respectful process, our point of differentiation isn’t about the steps in our process. Instead, it can be found in our ability to quickly assess your marketing organization and diagnose the causes of your agency pain points, and then to build a process that enables the most qualified agencies to customize their best teams and their best solutions to your organization’s nuanced needs.

Our process will lead you through an immersive experience with each agency finalist in which you will test and discover each agency’s creativity, thought leadership, and overall fit. To do this, we provide clarity and constructive feedback to the agencies at every point in the process, lighting a path for them to better tailor their solutions. We foster a collaborative and transparent environment where trust is earned and the stage is set for a future partnership.
