  • Late-Stage and Capital Markets Focus

    Megan advises companies at the most consequential moments in their growth, from late-stage private financings through IPOs, follow-on offerings, and other complex capital markets transactions on U.S. exchanges. She represents both corporate issuers and leading investment banks, and brings substantial transactional experience to every stage of the public markets journey for high-growth and innovative companies.

  • Trusted Governance Counsel to High-Growth Companies

    Boards and management teams at some of the most dynamic private companies rely on Megan as they scale toward the public markets. She advises on corporate governance, SEC compliance, and disclosure, helping companies build the infrastructure and board-level sophistication required to operate successfully as public companies.

  • A Leader at the Firm's Highest Level

    Megan joined Wilson Sonsini in 2014 and made partner in 2017, later joining the firm's board of directors. In July 2026, she became chief executive officer, alongside Caz Hashemi.

     

Megan Baier is chief executive officer of Wilson Sonsini and a member of the firm’s board of directors. As CEO, she is responsible for firm strategy, culture, and talent, and leads the day-to-day management of the firm’s business performance, including its operations, financial results, growth, AI and innovation, and risk management.

Megan has spent her career advising founders, boards, and public companies through the moments that define them: first financings, public offerings, and the governance decisions that follow. As a member of Wilson Sonsini's New York corporate group, she combines deep technical command of securities law with the judgment and steadiness clients need when the stakes are high.

Megan’s practice covers general corporate representation, public offerings, venture financings, and M&A, with a particular focus on innovative companies. She has worked with companies across every stage of the life cycle, from formation and early-stage financing through listing on U.S. exchanges, and regularly represents both corporate issuers and leading investment banks in public offerings. She also advises public companies on governance, SEC compliance, and the disclosure challenges that come with scale.

Clients come back to Megan for her technical precision, but they stay because of the relationship. She translates complexity into clear choices and stays engaged through the process, not just at closing. That trust was reflected in her selection, alongside Caz Hashemi, as Wilson Sonsini's chief executive officer. Before joining Wilson Sonsini in 2014, she practiced at Ropes & Gray and Skadden Arps.

Wilson Sonsini Advises InstaLILY AI on $60 Million Series B
On July 14, 2026, InstaLILY AI, creator of Lily, the world's first AI Forward Deployed Engineer, announced a $60 million Series B round led by Energize Capital. The round included participation from Insight Partners, which increased its investment, and new strategic investors including Home Depot Ventures and United Rentals. The Series B brings InstaLILY’s total raised to nearly $100 million, after a year in which the company’s revenue grew by a multiple of five. Wilson Sonsini Goodrich & Rosati advised InstaLILY on the transaction.

Lily goes into a business, learns how it works, builds what the work needs, and gets it running by finding revenue, pricing quotes, planning routes, and diagnosing equipment in the field. Unlike a traditional demo or pilot, it runs the business with people in control, and it goes live in days versus months. After launch, it keeps shipping and gets better the longer it runs. InstaLILY will use the Series B funding to help Lily learn faster, take on more of the work, expand into new industries, and grow the team. The company will also continue building the Small Data Center, the infrastructure that makes always-on intelligence possible inside a business, at a cost and energy profile enterprises can sustain.

The Wilson Sonsini team that advised InstaLILY on the transaction included Megan Baier, Sam Obenhaus, and Richard Fielkow.
