Markel Group Inc.
An insurance-focused holding company, Markel Group runs a specialty insurance business plus owned operations from precast concrete to ornamental plants and IT consulting. It traces back to 1930, when Samuel A. Markel began insuring "jitney" buses—nickel-fare rides most insurers refused to cover—setting a lasting knack for hard-to-place risks. Its guidepost, The Markel Style, is a short values statement written in 1980 that still steers its leaders.
