Can I register without an idea?

Wholeheartedly yes. 

After you register, you will receive an info pack. This includes guidance on how to brainstorm, explore, assess, choose, and validate startup ideas. And we recommend that you explore multiple ideas before choosing one; quantity yields quality.

And if you need more help, we also have a Workshop in September, where we will guide you in-person on the whole ideating process, and give tips on the best practices for your pitch video.
