About Jay

Jay is a leader in McKinsey’s Technology, Media & Telecommunications Practice, and global leader of Fuel by McKinsey, which serves the start-up and scale-up ecosystem.

Recently, Jay helped several software-as-a-service (SaaS) companies activate growth strategies through entering new verticals, geographies, and adjacencies, or by implementing new pricing and packaging models. He helped an early-stage food company develop a new business model and a go-to-market model, as well as helping an insuretech provider successfully launch new markets. Jay also supported a leading global venture capitalist in its sales of a unicorn cybersecurity asset, and helped a fast-growth tech company drive revenue growth in its telecom vertical.

Jay has also led several large-scale transformation engagements, focused on improving operating expenditures, customer experience, and digital channels. He recently led the holistic transformation of a leading global media company, identifying $1 billion in operating-expenditure reduction, of which $650 million was saved in the first 18 months of implementation.

Jay also generated significant cost reduction and improved customer care metrics for telecom operators. He helped a large US wireless operator achieve over $4 billion in cost reduction while becoming a market leader on digital-related sales and customer care metrics, and a LatAm operator achieve $1 billion in cost reduction and improved Net Promoter Scores.

Jay has been an active speaker at industry conferences on a range of technology topics, and is passionate about growing value across the start-up and scale-up ecosystem. Jay holds a BS with highest honors and MS in materials science from Columbia University, and a PhD in physics from MIT. Prior to joining McKinsey, Jay worked as a research associate at MIT Lincoln Laboratory.
