Overview

Mavenly combines opportunity discovery, proposal drafting, application management, and reporting. Its discovery module matches organizations to federal, foundation, and corporate grants, scoring fit against mission, geography, budget band, and grant history. That emphasis on organizational fit should help teams focus their search, while the platform’s pipeline tools carry work through deadlines, funder relationships, and outcomes reporting.

Compose AI drafts proposals using an organization’s previous submissions and a funder’s evaluation rubric, then exports them as DOCX or PDF. This makes it more than a standalone grant-writing assistant: teams can keep discovery and application tracking alongside drafting. Organizations that only need writing support may find the broader workflow unnecessary.

Native integrations include Slack, Google Workspace, and Microsoft 365; CRM integrations include Salesforce, HubSpot, and Bloomerang. Mavenly says it encrypts data in transit with TLS 1.2 or higher and at rest with AES-256, and does not use customer data to train its AI models or third-party models for general use. Its inference uses Anthropic’s Claude API with zero-data-retention endpoints. The company identifies itself as pre-launch on its security page; SOC 2 Type II is in flight, while ISO 27001 and HIPAA readiness are planned. Organizations that require completed certifications should look elsewhere for now.

Key features

Discovery and drafting

Fit scoring uses mission, geography, budget band, and grant history rather than treating every opportunity as equally relevant. Compose AI draws on past submissions and the funder’s evaluation rubric, a useful pairing for organizations that want drafts grounded in their own work and the application criteria. DOCX and PDF export supports taking those drafts into external review or submission workflows.

Application workflow

Pipeline and application management, deadline tasks, funder relationship tracking, and reporting and outcomes tools connect the search to the work that follows. The practical advantage is coverage across a grant cycle; the trade-off is that Starter’s active-application and drafting caps may constrain teams managing several concurrent submissions.

API access

API availability depends on the plan. Starter has no API access, Team provides read-only access, and Enterprise includes read-and-write access. That progression matters for teams choosing whether Mavenly is a standalone workspace or part of a broader software stack; API request tiers also appear under Developer / Pilot, Professional / Scale, and Enterprise Data Feed.

Pricing

Mavenly has no free plan. Starter begins at $49.00 per month, and the 14-day guided trial mirrors its limits: two authorized users, up to 10 active applications, 50 funder matches, and 25 AI drafts. The workspace becomes read-only when the trial ends unless the customer subscribes, so the trial is for evaluation rather than continued free use.

Plan	Price and terms	What it includes
Sandbox	$0.00 per free	500 requests per month, 2 requests per second, daily data refresh, and documentation only.
Starter	$49.00 per month, or $468/year	Two authorized users, up to 10 active applications, 50 monthly funder matches, 25 monthly AI drafts, email support with a 72-hour SLA, and no API access.
Developer / Pilot	$199.00 per month; annual billing available at ten months’ price	15,000 requests per month, 10 requests per second, daily refresh, and email support.
Professional	$299.00 per month, or $2,988/year	Up to five authorized users, unlimited active applications and matches, 200 monthly AI drafts, and email support with a 48-hour SLA. No SSO or advanced security.
Professional / Scale	$699.00 per month; annual billing available at ten months’ price	100,000 requests per month, 30 requests per second, hourly refresh, and priority email support.
Team	$799.00 per month, or $7,988/year	Up to 15 authorized users, unlimited AI drafts, read-only API access, and priority support with a 24-hour SLA.
Enterprise	$1,500.00 per contact; annual contracts only	Unlimited authorized users, read-and-write API access, SAML SSO and SCIM, custom integrations, and a 99.9% uptime SLA. Net 30 invoicing; implementation fee additional; multi-year discounts available.
Enterprise Data Feed	Custom pricing; annual billing available at ten months’ price	5,000,000 requests per month, 100 requests per second, continuous sync, and a named technical account manager.

Starter is the entry point for a small grant team that can work within its two-seat, 10-application, and monthly matching and drafting limits. Professional removes the application and match caps and raises drafting to 200 per month, but still limits the team to five authorized users and does not include SSO or advanced security. Team suits larger groups that need unlimited drafts and read-only API access; organizations that need write access, SSO, SCIM, or custom integrations must move to Enterprise. The Developer / Pilot, Professional / Scale, and Enterprise Data Feed tiers are oriented around request volume and refresh frequency rather than the grant-workflow quotas shown for Starter through Team.

The annual options are stated as savings for Starter, Professional, and Team. Developer / Pilot, Professional / Scale, and Enterprise Data Feed offer annual billing at ten months’ price. Enterprise requires an annual contract and adds an implementation fee; the Enterprise Data Feed has custom pricing.

Platforms

Mavenly is available on web and through an API, though API access varies by plan. The site lists a mobile app as coming in Q1 2027, so teams needing mobile access should not count on it now.

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. It fits organizations that need discovery, drafting, application coordination, and reporting under one roof, especially once they exceed a small number of active grants. Smaller teams may find Starter’s limits workable; teams with higher application volume, more collaborators, or security and integration requirements should budget for higher tiers.

It is less suited to users who want a permanent free grant-writing tool, need a mobile app now, or require completed SOC 2 Type II, ISO 27001, or HIPAA readiness before adoption. Listed support commitments range from 72-hour email support on Starter to dedicated customer success on Enterprise; the company says it responds to inquiries within two business days.

Pros and cons

Pros: Discovery, rubric-informed AI drafting, application management, deadline tasks, funder tracking, and outcomes reporting span the grant cycle.
Pros: Slack, Google Workspace, and Microsoft 365 integrations, plus integrations with Salesforce, HubSpot, and Bloomerang, give teams several ways to connect existing tools.
Pros: Starter offers a low-cost entry for up to two authorized users, and the higher workflow plans scale to unlimited applications or drafts.
Cons: There is no free plan, and the trial workspace becomes read-only after 14 days without a subscription.
Cons: Starter caps applications, matches, drafts, and users, and provides neither API access nor faster-than-72-hour email support.
Cons: Completed security certifications are not yet in place, and the mobile app is not due until Q1 2027.

Alternatives

Instrumentl is a paid web and API alternative with a free trial; its Discover plan is $299.00 per year, billed at $299 per month and paid upfront annually, or $349 paid monthly, for up to three users. Choose it when that plan’s pricing and user allowance better fit your grant-search needs.

Grantable has a free plan with five chat messages a day and file imports up to 10 MB, with every capability included. Its Starter plan costs $50.00 per month and allows 50 chat messages a day. Choose it if a free, web-based writing tool is a better fit than Mavenly’s managed grant workflow.

Grantboost offers a free plan with 10 Writer chats and 10 grant views per month, and a Find Grants plan displayed at $32 per month with annual billing. Choose it if those free monthly limits or its lower-cost grant-finding plan suit your needs.

Verdict

Mavenly is a strong fit for grantseekers and grantmakers that want discovery, drafting, application management, and reporting in a connected platform. Its workflow breadth, integrations, and scalable user and API tiers are the main reasons to choose it. Look elsewhere if you need a lasting free plan, a mobile app today, or completed security certifications; even a small team must also decide whether Starter’s application and drafting caps leave enough room to grow.
