• No published angel-investing thesis, check-size, or startup focus could be verified for Mark Miertschin.
• In his professional capacity, his "deal" focus is corporate acquisitions of producing oil & gas assets — mature, cash-flowing onshore U.S. properties — rather than venture/startup equity. He has a track record coordinating $5B+ in producing-asset acquisitions at Sheridan.
• Founders seeking a technology/seed angel should treat the "angel investor" classification as unconfirmed until verified directly.
