Peter Huff has invested in firms making mannequins, school uniforms, branded packaging, equipment for saw mills, boat covers and steam sterilizers . . . and then there are TV stations, oil & gas waste disposal operators and a tree transplantation service. The current and exited firms in the Blue Sage Capital portfolio are eclectic, and yet they do have a few characteristics in common: they are in niche industries, family owned, close to Texas and at or near industry leadership.
