Overview

Mavenly brings opportunity discovery, proposal drafting, and grant administration together. Its matching scores federal, foundation, and corporate opportunities against an organization’s mission, location, budget band, and grant history. Compose AI drafts proposals using prior submissions and a funder’s evaluation rubric, with DOCX and PDF export. Pipeline tools cover applications, deadlines, funder relationships, reporting, and outcomes, giving teams a place to manage work beyond the initial search and draft.

That breadth will matter most to organizations coordinating multiple applications. A team seeking only occasional writing help may find the management layer more than it needs. Integrations include Slack, Google Workspace, and Microsoft 365, alongside CRM integrations for Salesforce, HubSpot, and Bloomerang.

Mavenly says it encrypts data in transit with TLS 1.2 or higher and at rest with AES-256. It says customer data and prompts are not used for general model training, and that AI inference runs through Anthropic’s Claude API using zero-data-retention endpoints. The company describes its security status as pre-launch: SOC 2 Type II is in flight, while ISO 27001 and HIPAA readiness are planned. Organizations that require completed certifications should account for that status.

Key features

Opportunity matching and drafting

Matching considers several organization-specific factors rather than just returning a broad opportunity list. Compose AI’s use of prior submissions and a funder’s rubric gives proposal drafting a defined context, and DOCX or PDF export supports taking drafts into common document formats. The usefulness of this workflow depends on whether the monthly match and draft allowances fit the team’s volume.

Application management

Deadline tasks, pipeline and application management, funder relationship tracking, and reporting and outcomes tools address the coordination around each proposal. This makes Mavenly a stronger fit for teams managing an ongoing grant portfolio than for a single-project writer.

API and data options

The plans split between grant-workspace tiers and request-based API or data-feed tiers. Starter has no API access; Team offers read-only API access, while Enterprise includes read-and-write access. The Enterprise Data Feed offers continuous sync and a named technical account manager, but has custom pricing.

Pricing

Mavenly is paid, with a 14-day guided trial and no free grantseeker plan. The trial mirrors Starter: two authorized users, up to ten active applications, 50 funder matches, and 25 AI drafts. When it ends, the workspace becomes read-only unless the customer subscribes, so it is a limited evaluation rather than an ongoing free option.

Sandbox: Free, with 500 requests per month, 2 requests per second, daily data refresh, and docs only. Its API-oriented allowance does not provide the grant-workspace limits listed for Starter.
Starter: 49.00 USD per month, or $468/year — save 17%. It allows two authorized users, ten active applications, 50 monthly funder matches, and 25 monthly AI drafts, with email support at a 72-hour SLA and no API access. This is the lowest paid entry for a small team, but the application and drafting caps can constrain regular grant activity.
Developer / Pilot: 199.00 USD per month, with annual billing available at ten months’ price. It includes 15,000 requests per month, 10 requests per second, daily refresh, and email support. This is a request-based tier rather than a stated expansion of Starter’s grant-workspace quotas.
Professional: 299.00 USD per month, or $2,988/year — save 17%. It raises the allowance to five authorized users, unlimited active applications and matches, and 200 monthly AI drafts, with a 48-hour email support SLA. It suits teams whose application or match volume exceeds Starter, but still caps drafting and excludes SSO and advanced security.
Professional / Scale: 699.00 USD per month, with annual billing available at ten months’ price. It provides 100,000 requests per month, 30 requests per second, hourly refresh, and priority email support for request-based workloads.
Team: 799.00 USD per month, or $7,988/year — save 17%. It includes 15 authorized users, unlimited AI drafts, read-only API access, and priority support with a 24-hour SLA. This is aimed at larger collaboration needs, though the API remains read-only.
Enterprise: 1500.00 USD per contact, annual contracts only, with Net 30 invoicing, possible multi-year discounts, and an additional implementation fee. It includes unlimited authorized users, read-and-write API access, SAML SSO and SCIM, custom integrations, and a 99.9% uptime SLA. It fits organizations needing those controls and terms, with total cost affected by implementation.
Enterprise Data Feed: custom pricing, with annual billing available at ten months’ price. It includes five million requests per month, 100 requests per second, continuous sync, and a named technical account manager.

Platforms

Mavenly is available on web and through an API. A mobile app is listed as coming in Q1 2027, so teams needing a mobile app now should not plan around that offering.

Who it's for

Mavenly offers editions for grantseekers, including nonprofits and higher-education advancement teams, and for grantmakers such as private and community foundations. Its combined discovery, drafting, tracking, and reporting workflow is most relevant to organizations that coordinate multiple grants and can budget for a paid system. Smaller or occasional users may find Starter’s quotas restrictive, while larger teams can consider Professional or Team based on their application, drafting, and seat needs.

Pros and cons

Pro: Discovery, rubric-informed drafting, application tracking, and reporting sit in one platform, covering several stages of grant work.
Pro: Starter sets clear limits at two users, ten active applications, 50 monthly matches, and 25 drafts, so a small team can judge whether its workload fits before moving up.
Pro: Professional and Team remove match and application caps, with Team also offering unlimited drafts and up to 15 authorized users.
Con: The trial lasts 14 days and becomes read-only afterward without a subscription; it does not provide a continuing free grant-workspace tier.
Con: Starter has no API access, and Professional still lacks SSO and advanced security, which may rule out those tiers for organizations with integration or security requirements.
Con: Mavenly identifies itself as pre-launch on security certifications, with SOC 2 Type II in flight and ISO 27001 and HIPAA readiness planned.

Alternatives

For a broader comparison of grant-writing tools, see Nonprofit Grant Writing Software. Consider these alternatives when their free access, project limits, or pricing model better matches your needs:

Granted AI has a free plan and free trial, so it may suit readers who want to compare a no-cost entry point.
GrantAppli offers a free plan for three grant projects, a fit for users whose workload stays within that cap.
ProposalMint has a free plan with profile building, opportunity browsing, match scoring, and readiness assessment for readers seeking those capabilities without an initial paid plan.
Grantable offers a free plan with five chat messages a day and file imports up to 10 MB; it may appeal to readers who want to start with a capped free tier.
Grantboost offers a free plan with ten Writer chats and ten grant views per month, making it an option for a modest monthly workload.
Grantivo offers a free plan with ten credits and unlimited proposals and drafts, for readers whose needs fit its credit allowance.
Grantora has a free Community plan capped at four grant project outputs per year, with one admin and one writer user; consider it if that annual limit fits.
WinMyGrant offers a free plan for three proposals per month, a clear option for readers with a small proposal volume.

Verdict

Mavenly is best for nonprofits, advancement teams, and foundations that want discovery, proposal drafting, and grant administration in one paid workspace. Its main case is the breadth of the grant workflow, backed by defined collaboration and API tiers. Look elsewhere if you need a lasting free grantseeker plan, higher entry-level quotas, or completed security certifications before committing.
