FAQ
Is GrantChain a free alternative to Foundation Directory Online?+
GrantChain is free for browsing — no login, no paywall. Foundation Directory Online (FDO) by Candid starts at $35.54/month for the Essential plan and $126.58–$219.99/month for Professional. But they serve very different audiences: FDO is built for nonprofit prospect research (foundation 990s, grantmaker profiles, giving history), while GrantChain focuses on for-profit founders chasing non-dilutive capital like SBIR, EIC, Innovate UK, and Web3 ecosystem grants. They are largely complementary tools.
How does GrantChain compare to FDO on grant data?+
FDO has 235,000+ grantmaker profiles and 22.5M+ historical grants — almost entirely US private foundations supporting nonprofits. That data is research-grade and excellent for prospecting. GrantChain has fewer total listings but every one is a current opportunity for-profit founders can apply to: SBIR, EIC, Innovate UK, NLnet, Ethereum Foundation, Singapore EDB, Hub71, Frontier Climate, etc. Different categories of money entirely.
Does GrantChain have features FDO does not?+
Yes. Our AI Drafter generates a complete tailored grant application from a 5-minute project description for $35 per draft — FDO is a research database, not a writing tool. We also auto-import daily from Grants.gov and SBIR.gov, while FDO is updated by their editorial team. We also cover EU, UK, and Asia grants which FDO has very limited data on.
Why is FDO so much more expensive than GrantChain?+
FDO maintains a massive research database (235K+ grantmaker profiles, 22.5M+ grants, deep 990 financial data, recipient profiles, LinkedIn integration) — that level of data takes a large editorial team to maintain. They charge accordingly. GrantChain takes a different approach: a smaller, curated directory of currently-open grants for founders, with most of the value in the AI Drafter and the matching quiz. Different products serving different needs.
Can a US-based for-profit founder use FDO?+
Technically yes, but most of the data won't apply to you. FDO's database is overwhelmingly private foundations supporting US nonprofits — those organizations rarely fund for-profit companies. As a startup founder, you're better served by GrantChain (curated for you), Grants.gov directly (federal opportunities), or industry-specific resources like SBIR Topics for your sector.
Can a nonprofit use GrantChain?+
You can browse it, but you probably won't find what you need. We deliberately don't cover most US private foundation grants — that's FDO's territory and they do it well. We focus on grants for-profit founders qualify for: SBIR, EIC, government innovation programs, Web3 ecosystem grants, climate tech buyers like Frontier, and similar.
