What Door does
Door (Door Global) is a London-based boutique strategy consultancy founded in 2015 by Lee Sankey. The firm specialises in growth strategy, brand development, category design, product discovery and development, and experience and service design, working with global brands to create new value propositions and customer experiences. Its most notable publicly attributed project is masterminding Sky Glass, Sky's entry into physical televisions, which positions the firm around category-creating work for major consumer and media brands.
Operationally, Door is a small (1–10 employees), privately held, founder-led advisory practice without a technology product, app, or API. It does not publicly disclose pricing, customer lists, or revenue. Client references appear to be drawn primarily from founder Lee Sankey's broader career, which spans Group Director of Customer Experience and Innovation at Barclays (where he created Entrepreneurial Banking, Barclays Rise and the Barclays Accelerator), Managing Director of Voxygen, and a leadership role at Pipex Communications PLC. He simultaneously serves as Managing Partner of Sense Worldwide and as advisor to DeepTech Labs at Cambridge University and the Northern Gritstone project, indicating an ecosystem of affiliated but legally separate engagements rather than a unified platform.
Go-to-market is founder-led and referral-driven: Lee Sankey's personal newsletter and YouTube channel (over 2 million views) function as the primary public channels, with the firm's website (doorglobal.com) as the central hub. There is no evidence of institutional investment, external ownership, partnerships, or a formalised service-line structure, leaving the practice's economics, retention and forward trajectory heavily dependent on a single principal.
