Applications for Sprint batch close on March 7th 2018: http://vestbee.com/org/reaktor
For the last 6.5 years we have been simultaneously building our own companies and helping other entrepreneurs succeed. This is Reaktor spirit! We've been meeting founders who struggled getting an investment, as well as investors who struggled finding interesting startups. We've been meeting programmers who preferred coding to customer development and hustlers who could not find the right tech co-founder to build the products they dreamed of. Now it's time to use what we've learned by launching a first of its kind program for early stage startup founders, ReaktorX.
ReaktorX is most suited for:
- Professionals. Are you successful in your current profession but looking to build something that scales?
- Programmers. Are you a programmer, designer or computer science student not satisfied with building another boring website?
- Students with great ideas. Are you a student interested in entrepreneurship and looking to build something great?
