Microsoft 365 Copilot expands with PitchBook data and Excel 'skills'

Microsoft expanded its 365 Copilot ecosystem on two fronts. PitchBook launched a federated Copilot connector that pipes private-capital-market data directly into Microsoft 365 Copilot surfaces — Copilot in Excel, Copilot Chat, and Researcher — letting finance professionals query deal, fund, and company data without leaving their workflow. It's a concrete example of third-party data providers plugging into Copilot as a distribution and productivity layer.

Separately, Satya Nadella announced Microsoft is bringing 'skills' to Copilot for Excel, which he framed as 'a new way to scale their expertise across every workbook.' The post drew over 3,700 likes on LinkedIn, and Ethan Mollick highlighted skills more broadly as a promising way to standardize AI use inside firms — a recurring theme this week as the industry shifts from chatbots to configurable, task-specific agentic systems.

Microsoft also landed an enterprise win: Irish contract-research-organization giant Icon named Microsoft its technology partner, deploying Copilot and data infrastructure enterprise-wide to scale its agentic AI platform, Orbis. That continues the pattern of large regulated enterprises standardizing on a single hyperscaler's AI stack — paralleling Samsung's OpenAI deployment and AWS's Innovaccer deal in healthcare.

The strategic read: Microsoft is racing to make Copilot the default agentic layer inside the apps knowledge workers already live in, using data partnerships (PitchBook) and 'skills' to deepen lock-in. Watch how 'skills' adoption plays out as a standardization mechanism, and whether federated connectors like PitchBook's become a common pattern for embedding proprietary data into Copilot.
