The scheduling problem at Silverstone Advisory

Managing Directors routinely missed critical transaction windows due to calendar scheduling friction between international target boards, buyer groups, and legal counsels.

  • Executive assistants spent up to 20 hours per deal merely coordinating multi-party advisory calls
  • Strict regulatory confidentiality prevented sharing open calendar availability links
  • Time zone differences between London, Frankfurt, and New York complicated urgent deal closing meetings
