This article breaks down how EWOR and Arthur Rock Center for Entrepreneurship compare across five key areas – programme structure, mentorship, funding, network, and selectivity – so you can choose the platform that best matches your ambition.

1. Programme Structure and Educational Support

Both EWOR and Arthur Rock Center for Entrepreneurship offer structured programmes designed to help entrepreneurs grow. But they differ significantly in depth, flexibility, and global access.

EWOR offers two core fellowships:

• Ideation Fellowship, for refining and validating early-stage ideas

Both combine founder-led education, expert mentorship, and startup-building resources tailored to your stage. The experience is modular and remote-first – designed to move with you, not slow you down.

Each programme combines founder-led education, real-world mentorship, and global access.

From validating ideas to securing your first term sheet, the modules are tailored to support you and your journey as a founder.

One of the key differences between EWOR and Arthur Rock Center for Entrepreneurship is the access to funding. EWOR provides up to €500,000 in funding for selected startups, offering crucial financial support in the early stages. Beyond that, EWOR connects participants with a global network of investors, venture capital firms, and angels. Fellows also take part in what is called the “Grand Pitch”, an exclusive event where they present to hundreds of vetted investors, helping reduce fundraising time by over 80%. On average, EWOR founders raise 130% more than typical pre-seed startups at 2.5x higher valuations, thanks to the quality of the network and hands-on support. It’s not just about finding capital - it’s about raising smarter, faster, and on better terms.
