Thompson Legal Advisory Services

What Thompson Legal Advisory Services does

Thompson Legal Advisory Services P.C. is a boutique law firm founded in February 2000 by Managing Partner Tamara Thompson and headquartered at One Sansome Street, Suite 1400, San Francisco, with a remote operational presence in London via team member Jeffrey Smith. The firm operates across five practice areas: Financing Transactions (angel, seed, and venture capital financings, secondary sales, exits, private tender offers, venture debt), Mergers, Acquisitions and Divestitures, Start-up and General Corporate Matters (entity formation, financings, flip transactions, stock option plans, IP assignments, corporate governance), Commercial Matters (licensing, technology agreements, IP transfers, Terms of Service, Privacy Policies, US data privacy, employment-related agreements), and Fund Investments (fund vehicles and SPV LP review for VC funds, family offices, and other investors). The client base spans venture capital and investment firms (Ridge Ventures, Heartcore, London Venture Partners, Initial Capital, Broadway Angels, Silver Lake, Index Ventures, Accel), Fortune 500 and large enterprises (eBay, Intel, Agilent, GAP Inc., NNIT), and a long roster of technology startups and founders across gaming, biotech, real estate, education, and enterprise software.

The business model is classic professional services: custom-quoted engagements billed to clients based on matter complexity and scope, delivered through direct engagement backed by written engagement letters. There is no proprietary technology platform; the firm's assets are the expertise and relationships of its lawyers, notably Tamara Thompson's personally-attributed track record of over 1,000 financing transactions, hundreds of M&A deals, and 40+ public offerings. Over 80% of work is international, spanning the US, UK, and additional geographies, with cross-border execution enabled by Managing Partner and Finance & Operations team members dividing time between San Francisco and London. Distribution is overwhelmingly relationship- and referral-driven, supported by a professional website (tlaspc.com) and a LinkedIn presence tied to the Managing Partner. The firm is GDPR- and CCPA-aware, with Jeffrey Smith designated as Data Protection Officer.

The team is compact: Tamara Thompson (Managing Partner), Kate Kirby (Senior Counsel; joined February 2005), Lisa Mertens (Corporate Governance Specialist), and Jeffrey Smith (Finance & Operations). There is no disclosed institutional ownership, no funding rounds, no subsidiaries, no parent company, and no public-company registration; the entity is a California professional corporation. Operations are founder-led and have been stable across the 25-year history, with no recorded M&A, leadership turnover, or material restructuring events in source material.
