What Grantseeker does

Grantseeker is a cloud-based grant management and funder prospecting platform serving US-based tax-exempt nonprofit organizations, with additional users in the UK, Canada, New Zealand, and Australia. Founded in 2017 as a product line within Fluxx Labs, Inc., it was spun out as an independent company in April 2023 under President Nathaniel B. Chase, and was re-acquired by Fluxx Labs, Inc. in November 2025, now operating as a business unit under President Becker Chase.

The platform is delivered as a multi-tenant SaaS application accessible via web browsers, with two distinct product lines. Grantseeker Classic offers grant tracking, deadline management, calendar and Google Drive integration, custom fields, reporting, and an optional Prospecting module backed by a proprietary 2.8M+ record foundation database derived from IRS 990 filings (including 500,000+ private foundation reports). Grantseeker Pro is an enterprise-grade platform for governments and large nonprofits managing $1M+ in grants, featuring multi-account architecture, SSO and role-based permissions, custom pipeline stages, federal funds and SEFA reporting, a developer API (OpenAPI v3), and formula-based pricing. Supporting infrastructure includes an AWS OpenData-sponsored open S3 bucket of cloud-optimized 990 data with ~48hr sync latency, a freely accessible Open Search site (search.grantseeker.io), Stripe-powered subscription billing, and integrations with Google Calendar, Microsoft Outlook, and Apple iCal.

Grantseeker operates a hybrid go-to-market: a self-serve product-led growth motion for Classic with a free Basic tier, a 14-day free trial on Premium and Prospecting, and an enterprise field-sales motion for Pro with demo requests and custom quotes. Revenue is generated primarily through subscription billing (Premium at $19.99/month, Prospecting at $51.99/month, Pro via formula-based enterprise contracts), supplemented by a referral credit program ($20 per paying customer referred). The company reports serving 3,000+ nonprofits since 2017 and tracking $10.2B+ in 990 filing datapoints.

Core offering

Grantseeker provides a cloud-based grant management and prospecting platform that helps nonprofits, foundations, and government agencies find, apply for, and track grants. The product line spans a self-serve SaaS application (Grantseeker Classic) with a grant database and post-award tracking, an enterprise tier (Grantseeker Pro) configured for large organizations, and complementary open-data resources (OpenData Project on AWS and Open Search).

Product overview

Grantseeker offers two distinct platforms: Grantseeker Classic (a freemium model with Basic, Premium, and Prospecting tiers at $0-51.99/month) for small to mid-sized nonprofits, and Grantseeker Pro (formula-based enterprise pricing) for governments and large organizations managing $1M+ in grants. Both platforms share a common architecture for grant tracking, but Pro offers enterprise features like multi-account architecture, SSO, and SEFA reporting while Classic focuses on simplicity and affordability. The product ecosystem also includes a freely accessible Open Search site for prospect research and an OpenData project maintaining IRS 990 data in AWS. Grantseeker was acquired by Fluxx Labs, Inc. in November 2025 after operating independently from April 2023 to November 2025.

Expansion highlights5 records

Direct peers

• Submittable: Direct peer providing application and grant management SaaS used by foundations, nonprofits, and government agencies. Overlaps with Grantseeker Classic in grantee workflow and with Pro in grantmaker-side program management.
• Instrumentl: Direct peer offering grant prospecting, funder research, and matching tools for nonprofits. Instrumentl competes head-on with Grantseeker's Prospecting module and the IRS 990–driven funder search workflow.
• CyberGrants: Direct peer offering corporate and nonprofit grant management technology; comparable to Grantseeker Pro for large/enterprise grant portfolios, especially where compliance, multi-account, and audit workflows matter.
• GivingData: Direct peer providing grants management software specifically for foundations and grantmakers; comparable to Grantseeker Pro on the grantmaker-side workflow that sits adjacent to Grantseeker's grantee focus.
• Fluxx Labs: Parent company of Grantseeker since November 2025 and a direct peer in the grants ecosystem — Fluxx Labs provides grantmaking management software for foundations, while Grantseeker provides the matching grantee-side workflow. They sit on opposite sides of the same grant transaction.
• Foundant (GrantHub / Foundant GLM): Direct peer offering grant lifecycle management for nonprofits and grantmakers; Grantseeker is actively running a free-migration replacement offer against Foundant GrantHub, making this the most directly contested product in the space.

Broad incumbents

• Benevity: Broader incumbent in corporate philanthropy, grants management, and employee giving; overlaps with Grantseeker Pro on the grantmaking/grant-portfolio workflow and competes for large institutional customers.
• Salesforce (Nonprofit Cloud / NPSP): Broad incumbent CRM platform with the nonprofit-specific NPSP/Nonprofit Cloud offering; competes with Grantseeker for mid-market and enterprise nonprofits evaluating platform consolidation.
• Bonterra (formerly Network for Good): Broader nonprofit SaaS suite covering grants, donor management, and outcomes tracking; competes with Grantseeker for the same nonprofit buyers from a much wider product portfolio.
• Microsoft Cloud for Nonprofits: Broad incumbent platform offering nonprofit program management, fundraising, and engagement tools within the Microsoft cloud stack; competes with Grantseeker Pro for government and large nonprofit customers with existing Microsoft estates.
