In their own words
Grantboost
Grantboost is online software for finding grant opportunities, tracking deadlines and pipelines, and drafting proposals with AI. It says it monitors roughly 1.5 million funding sources and matches them to an organization’s mission and programs. Coverage is strongest in the United States; international opportunities may appear, but coverage outside the US is thinner. On plans that include drafting, the service analyzes RFPs and prepares proposal sections using an organization’s past proposals, programs, and voice. Users review, edit, and submit applications themselves, with a link to each funder’s application page. Drafts can be exported to standard document formats, while opportunity data can be imported or exported manually. The FAQ says there are no third-party integrations such as CRM, Zapier, or Google Docs sync. Workspace documents, drafts, and pipeline are visible only to invited people, and uploaded content is not used to train third-party AI models. The free plan includes 10 Writer chats and 10 grant views per month. Paid plans are displayed from $32/mo with annual billing.
Mavenly
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.
