Yes Absolutely! Asking a question is as simple as clicking 'Ask A Question' on a campaign page. Founder are welcome to answer you directly or can post the Question and Answer publicly in the Q&A tab if they feel many potential investors may ask the same question.
Alternatively, some companies elect to post their phone number or email address on their campaign page. Given the 'crowd' nature of our business, we encourage investors to be mindful of the founders time and only directly reach out when questions are urgent and/or serious.
