AV is the largest non-coastal venture capital firm in the United States, with $4 billion under management. Prior to joining AV, Thornton was with McKinsey & Co., where he served clients in the U.S. and Europe.

He serves on the advisory boards of the Harry Ransom Center at the University of Texas at Austin and the New American Foundation. He is a co-founder of the Austin Entrepreneur’s Foundation; a former trustee of Ballet Austin, where he co-chaired a successful capital campaign; a former trustee of the Austin Museum of Art, where he chaired strategic planning; and a former trustee of Trinity University.

He graduated first in his class from Trinity University, and he received an M.B.A. from Stanford University.
