The short version

  • Only Little Green Light has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Little Green Light pricing is driven purely by constituent record count, so inactive and lapsed records still raise the bill
  • They diverge on capability: Instrumentl covers Funder matching, Little Green Light covers Donor database.
  • Prices and features above were last checked on 31 August 2026.

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.

Little Green Light

  • Pricing is driven purely by constituent record count, so inactive and lapsed records still raise the bill
  • The base plan is $45 per month for up to 2,500 constituents, rising to $135 per month at 50,000
  • Above 50,000 records each additional 10,000 tier adds $15 per month
  • An account is hard-capped at 200,000 constituent records
  • Online donation processing costs from 2.2% plus $0.30 per transaction to the payment processor
  • The 10% saving requires annual rather than monthly billing
