Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

OpenGrants

  • Coverage of private foundations is thinner and less curated than Candid or Instrumentl, so a prospect list built solely from OpenGrants will miss foundations that never post public opportunity notices.
  • The index leans on public opportunity feeds, which means it is strongest on government funding and weakest on the relationship-driven private philanthropy that most nonprofits actually rely on.
  • Matching is keyword driven rather than fit-scored, so users receive alerts for opportunities they are ineligible for and must qualify each one by hand.
  • The consultant marketplace is a directory with variable quality rather than a vetted panel, so buyers carry the risk of choosing a weak grant writer themselves.
  • It is a US-focused index, offering little to organisations seeking UK, EU or Canadian funding.

SignUpGenius

  • Specific pricing for paid plans is not published on the main site; users must visit the dedicated pricing page to see exact costs

Answered from the vendors’ own pages

OpenGrants: How much does it cost?

$9 a month or $99 a year after a seven day trial, with a free tier of core search retained.

SignUpGenius: Does SignUpGenius offer a free plan?

Yes. SignUpGenius is free to start with no credit card required. The free plan includes core signup functionality without monthly fees.

Source
OpenGrants: Why is it so much cheaper than Candid?

Because it indexes public and semi-public opportunity feeds with automation rather than employing researchers to code foundation records from tax filings. You trade depth of private foundation intelligence for price.

SignUpGenius: What do paid SignUpGenius plans include?

Paid plans add more customization options, higher communication limits, and the ability to remove ads from your signup pages. Standard payment processing fees apply to payments collected through the platform.

Source
OpenGrants: Does it cover private foundations?

Partially. It is strongest on federal and state programmes. For systematic private foundation research, Candid remains the reference source.

OpenGrants: Is the consultant marketplace vetted?

It is a directory, not a vetted panel. Check references and past awards yourself.
