About this opportunity
Halcyon has moved its founder applications to a year round model, which means an impact focused venture can now be considered for a Halcyon fellowship without waiting for one fixed annual window. The change opens the first stage of the process to founders at any point in the year, and Halcyon reviews what arrives on a rolling basis.
The process has two stages. You begin with a short
Eligibility
Application that describes the venture, its mission, its stage of development, the impact it is chasing and the solution it is building. If that first review goes well and a fellowship opens that fits the work, Halcyon invites the venture to complete a much fuller Invitational Application, which is not available for independent submission.
One practical change matters most for preparation. A pitch deck is now required at the first stage, limited to 15 slides, and a one minute video about the venture is optional. A short video is a good place to show why the problem matters to you, which is hard to communicate in a written answer.
Halcyon is a founder community rather than a single programme, and its reach is international. Its 2024 Climate Fellowship drew applications from 69 countries, and the organisation describes a community of more than 650 impact driven entrepreneurs.
Eligibility
for any specific fellowship is confirmed at the invitation stage, so read the requirements Halcyon publishes on its own site before you invest time in the form.

Selection process
- Halcyon reviews Eligibility Applications on a rolling basis, with no fixed annual deadline for the first stage.
- The selection committee assesses ventures against four stated criteria: impact, scalability, innovation and talent.
- Impact looks at the problem you are solving, who it affects and how the change can be measured.
- Scalability looks at whether the solution can reach more people, markets or communities.
- Innovation looks at what is distinctive about the approach, not simply the claim that it is innovative.
- Talent looks at the founders, their experience, what they have already achieved and how the team complements one another.
- Ventures that meet the criteria may be invited to complete the detailed Invitational Application when an aligned fellowship opens.
