From Fair
to Funding
The Harenix Accelerator helps talented founders plant themselves in the Robinhood Chain ecosystem, iterate fast toward product-market fit and raise a seed round sooner.
The first two weeks happen in New York. The remaining eight run remote or in person, your choice. Founders get a private community, 1:1 mentorship, weekly sessions and an upfront investment from Harenix.
Only hackathon winners get considered. Harenix runs two fairs a year, and each one feeds a new cohort.
