Business Owners have an option of not displaying their contact details and name of the company even post the introduction. This can be revealed at any point in time the business owner sees fit.
Kindly note since the contact details are not displayed, post introduction the onus is on the business owner to reach out to the investor.  An investor will not be able to contact the business owner on phone or email. They can however, send a message using the SMERGERS messaging system.
On business profile, option to display contact and company details can be selected as per the image below
