Summary
Polsinelli has experienced a notable departure from its San Francisco venture capital team, with an emerging companies specialist rejoining rival firm Pillsbury Winthrop Shaw Pittman LLP as a partner. The move reflects intensifying competition among major law firms to secure and retain top talent in the high-demand emerging companies and venture capital (ECVC) practice area.

The departure occurs amid Polsinelli's broader expansion efforts. The firm has added 94 partners over the preceding two years, signaling sustained strategic growth investments despite lateral departures. This aggressive hiring strategy indicates Polsinelli's commitment to building scale and market presence across key practice areas, even as individual partners migrate to competing firms.

Polsinelli's venture capital practice, centered in San Francisco, serves emerging growth companies and venture capital investors across formation, financing rounds, and exit transactions. The firm maintains a dedicated team advising startups from pre-launch through IPO and M&A processes. Brian Willbur, a principal based in the San Francisco office, exemplifies the firm's ECVC specialist roster, offering counsel to both emerging companies and venture investors on transactional matters.

The lateral movement to Pillsbury reflects broader competitive dynamics in the venture capital legal market, where firms compete intensely for practitioners with deep sector expertise and established client networks. Pillsbury's deliberate expansion of its ECVC capabilities in Silicon Valley underscores the high-value positioning of specialized VC legal talent, particularly in Northern California's venture-dense market.

These talent flows and firm expansions are emblematic of structural changes in the legal services industry supporting venture capital and emerging growth companies, with established firms strengthening their platforms through lateral hires and internal growth investments.
