Philanthropies & Social Impact Organizations

Fast, scalable editorial support for mission-driven work.

When Ideas Arise from Passion

You have a mission. We help you communicate it with clarity, purpose, and impact. 

At Flatpage, we work with corporate philanthropies, foundations, and social impact organizations like advocacy or community groups to refine, tailor, and amplify their messaging for donors and funders, stakeholders, and other community members. Whether you’re preparing a grant proposal, launching a campaign, or updating your website, we help make sure your voice is compelling, consistent, clear, and aligned with your goals.

The organizations we support often have content written by internal teams—communications staff, program officers, researchers, or leadership. These projects may involve multiple contributors or stakeholders and require careful editing for consistency, tone, and accessibility across platforms. With limited time, personnel, and resources, nonprofits are often challenged to meet the high demands and tight deadlines of large, complex content and communications programs.

We specialize in editing a wide range of materials for nonprofits, including grant proposals, annual/impact reports, web copy, blog posts, white papers, social media content, and other donor-, stakeholder-, or public-facing communications. Our editors are trained to work sensitively with mission-driven language while maintaining professionalism and polish. Whether you need support for a one-time publication or an ongoing editing partnership, we provide fast, thoughtful, high-quality editorial services.

The services below are tailored to meet the needs of philanthropies and social impact organizations. For additional editorial offerings, please refer to our overview page.

  1. Line editing

    Bring clarity and cohesion to your message. Line editing refines your writing at the sentence level, improving flow, tone, and word choice. This service is ideal for content that needs to strike the right balance between passion and professionalism, from director’s letters and white papers to campaign pages and advocacy toolkits.

  2. Copyediting

    Make your communications polished, consistent, and credible. Copyediting ensures your content is grammatically correct, aligned with your preferred style guide, and ready for design or publication. It’s a great fit for materials with multiple authors or several rounds of revisions—grant proposals, donor briefs, newsletters, and more.

  3. Proofreading

    Final polish before going public. Proofreading is the final review to catch minor errors and ensure your document is clean and consistent. This step is essential for materials headed to layout or already in design, especially printed reports, fact sheets, and promotional flyers.
