"To Whom It May Concern", its most formal way to address person/authority whom you don't directly know. Many potential good candidate don't know company contact info or they are remote but interested to work with you. they may or may not be suitable for position but one should not ignore if they are too formal. Just read bio, Introduce yourself responsible person and shoot few questions and wait for personalized reply. If goes well do skype meeting.
