Eligibility

Our fellowships are open to for-profit impact-driven founders at or beyond MVP-Stage. Additional information is listed below under “Programs and Format”.

Halcyon defines “impact-driven” as a scalable company where impact forms a non-negotiable part of the business model. The startup’s impact drives meaningful and measurable progress towards one (or several) of the UN Sustainable Development Goals (SDGs). 

“MVP-stage” is defined as having a workable, or saleable version of your business concept. 

Benefits Halcyon Fellows receive training in: Investment Readiness, Product-Market Fit, and Leadership Development. Selected fellows also receive other program-specific benefits, including an equity-free stipend, $10,000 in AWS credits, professional advisors, network opportunities to meet investors and diverse stakeholders in the US.

Halcyon’s Fellowships for startups are free, with no fee or equity stake required.

Application Tips

Halcyon’s application is an opportunity for the selection committee to learn more about you, your venture, and your vision for impact. The committee reviews each application using Halcyon’s four criteria: Impact, Scalability, Innovation, and Talent.

Halcyon uses one application for the two fellowships we are currently recruiting for when you complete your application, you will select which program you would like to apply for. To support as many founders as possible, founders may only apply to complete ONE fellowship. 

It is now required to upload a Pitch Deck of up to 15 slides. You may also upload a 1 minute video describing your venture! This is a wonderful way to bring your application to life and showcase your passion and drive! At Halcyon we love supporting founders with a clear vision, strong ambition, and the drive to create dramatic positive influence.

You have until Sunday, February 16 at 11:59PM US Eastern Time to complete your application. The entire Halcyon Team is sending you luck and thank you for your interest in our Fellowships!
