## Chan Zuckerberg Initiative - Essential Open Source Software for Science (EOSS)

- free tier: No byte quota - $100,000-$400,000 total over two years, from which cloud/storage is a claimable line item. | unit: mixed | metered on: stored-bytes | read on: 2026-10-21 | source: [1]
- per-object cap: not stated | source: [1] | note: not stated
- retention: not stated | source: [1] | note: not stated
- egress: N/A - grant money, you buy the egress. | metered: no
- identity: institution | detail: the award is made to an organisation and never to an individual: an eligible nonprofit or for-profit organisation, public or private institution, or a fiscal sponsor such as NumFOCUS for a project with no institution of its own. The application form asks for the applicant's institution or affiliation and, separately, the award organisation, and the full proposal needs institutional sign-off. No card and no phone number is asked for.
- interface: unknown
- limits:
  - write-gated (binding): invited full proposal) [1]
  - write-gated (binding): applications from any country' subject to US export-control screening [1]
- limits note: Two-year grants. Two-stage (LOI then invited full proposal). Requires an organisation or a fiscal sponsor secured by the full-proposal deadline. 'We welcome applications from any country' subject to US export-control screening; non-US institutions cannot subcontract to US institutions if CZI funds it.
- interface detail: n/a
- tooling: the same as interface detail
- composes with: The eligibility bridge matters more than the money: 'Grants are not permitted to individuals, only to organizations' but a fiscal sponsor is allowed (NumFOCUS, Code for Science & Society). An individual with an OSS project applies through the sponsor and can then budget multi-year object storage explicitly.
- reliability: Cycle-based, not rolling - the current cycle page shows Cycle 6 closed, so timing is the gate. Large award, slow cadence.
- notes: the same as the free tier
- evidence:
  - [1] 2026-10-21: 'Grants are not permitted to individuals, only to organizations'; 'it may designate a fiscal sponsor (e.g., NumFOCUS...)'

  - [1] 2026-10-21: 'We welcome applications from any country, provided the proposed work is compliant with... OFAC'
  - [2] 2026-10-21: Cycle 6 $11.7M with Kavli and Wellcome
  - [1] 2026-11-01: a project with no eligible institution applies through a fiscal sponsor, which is the only non-institutional route | capture: sha256:5f1c38101cc909366cff3be29a01bb593c138dbf8f09134bca04be6dac18a032 | quote: it may designate a fiscal sponsor
  - [1] 2026-11-01: the request is $50,000 to $200,000 a year for two years, the $100,000 to $400,000 total over two years the record states | capture: sha256:5f1c38101cc909366cff3be29a01bb593c138dbf8f09134bca04be6dac18a032 | quote: Applications can request funding between $50,000 USD and $200,000 USD total costs per year for two years
