Harry Seip


Leads McKinsey’s digital and analytics work in Thailand and combines expertise in customer experience, core technology, and architecture to advise clients on digital transformations in the financial-services, retail, and telecommunications sectors

Harry leads McKinsey’s work on digital and analytics in Thailand. Before joining the firm’s Bangkok office, he spent several years in our Amsterdam office serving clients. An expert at building core technology platforms and bringing innovative digital experiences to clients, he is trusted by organizations across industries and geographies.

Harry has a deep understanding of digital-transformation journeys and has helped leading financial-services, retail, and telecommunications clients on a range of issues related to customer-journey design, core-system replacement, and agile capability building.

Examples of his recent client work include the following:

  • introducing an agile methodology, supported by a new technology platform and digital products, for a major bank
  • helping a large telecommunications company with a comprehensive transformation journey
  • advising a global insurance company on how to transform its technology and operating model across Asia−Pacific markets

Beyond serving clients, Harry plays an active role in Thailand’s burgeoning start-up ecosystem. A foodie at heart, he founded a Thai food-and-beverage business in the Netherlands prior to joining McKinsey.
