Our Philosophy

Transformational results in building a culture of philanthropy are found through:
Personal. Meaningful. These are the kinds of relationships you need for a sustainable culture of philanthropy. Donors who have the strongest relationships with you will typically make the greatest, lasting investments in your organization. The essential ingredient to building strong relationships is a cultivation strategy, one that includes consistent, meaningful and personalized communication.
Though you encourage contributions of all sizes from all sources, successful philanthropic efforts start with targeted, well-cultivated, high-end key gifts. These are most often from individuals who have a sustained relationship with you and your volunteer and internal leaders. Success in major gift development and securing major gifts can be achieved with the right, proven steps.
Committed. Involved. That’s the right kind of volunteer leadership you need to bolster staff efforts. Projects that meet or exceed goals are volunteer-driven. Build a corps of volunteer leaders that are dedicated to your organization and motivated to inspire others to give generously.
Those within the organization must lead by example to inspire the philanthropic support of donors and volunteer leaders. Though there may be varying degrees of participation and support, all members – regardless of title – must be advocates of the effort. Taking ownership of the development function and believing in what it will accomplish starts with top leadership and is reinforced through the organization.
The road to success is paved with your Case for Support. An effective case is built on your mission and a vision for the future. Facts and researched data provide the roots, but a strong case blossoms when compelling and passionate, providing key messages that resonate with and unite everyone around a common goal.

Our History

American City Bureau was incorporated on April 22, 1913. The beginning of the company happened through a series of events that can be traced back to 1911 when two Buttenheim brothers decided to stake their future on a magazine called The American City. This small monthly magazine had just started less than two years earlier, but was quickly failing under its existing management. The Buttenheim brothers had backgrounds in successful trade and technical journals – one was a businessman, the other an aspiring editor – so they divided the task between them based on their strengths.

The growth of the magazine under the Buttenheim brothers brought them in touch with municipal officials and Chambers of Commerce throughout the country. These civic-minded individuals made it increasingly evident that there was a need for a national organization to promote philanthropic activities through campaign techniques and research services which The American City had been advocating in its articles. The brothers understood this undertaking could not be done effectively through the magazine, so in April 1913 they formed a new corporation – American City Bureau.

In the beginning, American City Bureau focused on organizing and strengthening Chambers of Commerce. Over the next few years ACB branched out to working with libraries, YMCAs and other community organizations. Today, our work spans from youth and social services to religious orders and organizations to healthcare, education, community and the arts. Our fundraising consultant team has come a long way and we credit our rich history to our continued success in helping nonprofits realize the promise of growth.
