A significant hurdle will be an announcement that they have engaged a PCAOB Audit firm. Must have Audited Fins for OTCQB.
That typically takes several hundred thousand $dollars$ in fees, and 3-6 months for the Audit.
Add in that HIRU has lots of "housekeeping" to do to arrive at Audited Fins, and it could be awhile before HIRU reaches that milestone.
I'm butting in here, respectfully, because the subject has been brought up here a few times, and I just wanted to add in some of the requirements. Hopefully helpful and realistic. Good fortune.
