Every organization is reviewed before generation unlocks — usually within one business day. Selected organizations also get a live, screened AI demo before committing to a plan.
Full funding intelligence and unlimited document generation.
For organizations with multiple staff drafting and reviewing.
For INGO country offices and NGO networks managing sub-grantees.
Your matched funding feed is always free, on every plan. Broader Search runs on your own connected Anthropic API key (BYOK) and unlocks on Professional, Team, or Federation. Document generation is also BYOK — new subscribers get 3 free document-generation calls on Sigma's key to get started before connecting their own.

We manually review new organizations rather than opening the AI features to anyone who signs up — it keeps usage on the platform legitimate and lets us make sure Sigma NGO actually fits what you do before you pay for anything.
Tell us who you are and where you operate. No card required at this stage.
Usually within one business day. Some organizations are also invited to a short screening call.
Screened organizations can generate a handful of real documents on us — zero setup, no key required — before subscribing.
Choose a plan. You'll get 3 free document-generation calls on us to try it for real, then connect your own Anthropic API key to keep going — takes about a minute.
Yes, for ongoing use. Sigma NGO is bring-your-own-key (BYOK) — your key is encrypted and used only for your organization's own generations. You'll get a small number of Sigma-covered calls first, so you can see real output before setting your key up: a handful during a screened trial, and 3 more for document generation right after subscribing. Broader Search and donor fit-scoring always require your own key.
It keeps the platform's AI usage tied to real organizations rather than open self-serve access, and lets us confirm Sigma NGO is a good fit for how you work before you commit to a paid plan.
Usually within one business day. If you're invited to a screening call for early demo access, we'll reach out using the contact details from your registration.
Yes. Plans are month-to-month with no long-term contract. See our refund policy for details.
Nothing is lost. Starter includes your org profile, your automatically-refreshed matched funding feed, and your compliance calendar indefinitely — you can upgrade whenever you're ready to unlock AI document generation and Broader Search.
Set up your organization profile now — review and (where applicable) demo access follow shortly after.
