Where each one falls short

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

Instrumentl

  • The funder database is built largely from IRS 990 filings, which are filed months to years after the grants they describe, so matches reflect what a funder did rather than what it is doing now.
  • Coverage is strongly US-focused and weakest on federal and state government funding, so organisations whose income is mostly government contracts pay database prices for data they mostly cannot use.
  • Seat bands are hard limits, and a team of six on the five-seat Pre-Award tier must move to the 999 dollar tier, doubling cost for one extra person.
  • The annual discount requires paying twelve months up front, which is a real cash flow problem for the small nonprofits the entry tier targets.
  • AI drafting produces serviceable first drafts but funders increasingly screen for generic applications, so the time saved on writing tends to be spent on rewriting.

OneCause

  • No transparent pricing published; all plans require contacting sales at 888-475-5214 or online form for custom quotes
