Stelter

The Stelter Company focuses on planned giving marketing for nonprofits, a niche it has served since Paul J. Stelter founded the business in 1962. Nearly 1,500 nonprofit clients, ranging widely in size, work with the company from its 30,000-square-foot Des Moines headquarters, supported by more than 100 employees. Over the decades the company has shaped its offerings around this single focus, including releasing the first national, scientific study on bequest giving.

Services span direct mail marketing, digital marketing, data analysis, social media, donor surveys, and development training, alongside digital strategy, brand positioning, campaign management, and creative production. Stelter introduced planned giving websites as a managed service and later launched a digital marketing platform integrating web, email, and social media, reflecting a pattern of building tools specific to planned giving rather than general nonprofit marketing. Lead capture and follow-up, along with data hygiene and enrichment, round out the service list, pointing to work that carries donor prospects from initial contact through ongoing stewardship.
