Vignesh Kumar on Why Healthcare is Moving Faster in 2026 than the Entire Last 10 Years of SaaS

Healthcare has never moved this fast.

Pharma giants are no longer just buying software. They are writing $50 million checks for access to a single foundational model. Systems of record are being replaced, and the shift is unfolding fastest in a place most people did not expect: healthcare.

Vignesh Kumar, Partner at Sierra Ventures, has spent 13 years at the center of this enterprise shift. He has sourced and invested early in companies across Enterprise AI, including two unicorns, Phenom and Reify Health, with Reify reaching around a $4B valuation and Phenom crossing $1B.

Over 40 years, Sierra has backed 300+ startups, resulting in 11 IPOs, 7 unicorns, and 104 acquisitions, and manages over $2.4B in assets. Today, the firm is a focused early-stage enterprise AI investor, writing first institutional checks while staying disciplined on fund size, growing from $150M to $270M.

This episode is on how the next generation of companies in Enterprise AI will be found, funded and scaled. If you are building in AI or exploring healthcare, this will help you see the shift earlier and act on it with more clarity.
