Grantsville vs Mavenly

Grantsville is a paid web service for US nonprofits under $500K whose directors write grant applications. It reads an organization’s documents, beginning with its public Form 990, and links statements in drafts to source documents. The service prepares letters of inquiry, full proposals, and answers for funder portals, shaping portal responses to field limits. It flags numbers and claims for review before submission. Users can provide selected writing so drafts follow that voice, although Grantsville says generated text may be wrong or sound off. First-time grant writers can use it without a prior award. Grantsville describes itself as self-serve; a consultant may better fit complex strategy or funder relationships. It says drafting searches only the organization’s documents and does not use them for another organization. One first application is free with no credit card. A letter of inquiry costs $99, and a full application costs $299.

Mavenly is a grant funding platform for discovering opportunities, drafting proposals, managing applications, and reporting outcomes. Its discovery module matches organizations with federal, foundation, and corporate grants, scoring fit by mission, geography, budget band, and grant history. Compose AI uses an organization’s prior submissions and a funder’s evaluation rubric to draft proposals, which can be exported as DOCX or PDF. Management tools cover pipelines, deadlines, funder relationships, reporting, and outcomes. Listed integrations include Slack, Google Workspace, and Microsoft 365, plus Salesforce, HubSpot, and Bloomerang for CRM. Editions are available for grantseekers, including nonprofits and higher education advancement teams, and grantmakers such as private and community foundations. Starter costs $49 a month. The guided trial lasts 14 days and follows Starter limits: two authorized users, up to 10 active applications, 50 funder matches, and 25 AI drafts; afterward, the workspace becomes read-only unless the customer subscribes. The site lists web and API platforms; a mobile app is described as coming in Q1 2027.
