Yes. Once you submit your pitch, it will be reviewed by the Crowdcube team who, if necessary, may provide feedback to optimise your pitch. At this point, you will have the chance to edit and resubmit the pitch text, as well as your video and images if needed.
Once your pitch has been finalised and the verification process has started, you will no longer be able to edit your pitch text but your images and video can still be updated if required.
