Practice areas

Complex business litigation and startup / technology / venture law for San Francisco companies, founders, and investors. Our two anchor practices are supported by the full range of corporate services growing companies need.

Complex Business Litigation

Commercial Litigation

When a San Francisco business dispute escalates — shareholder actions, contract fights, trade-secret claims, securities litigation — you need lawyers who have handled the toughest cases. Our litigation team brings AmLaw-caliber depth to complex commercial disputes from pre-litigation strategy to trial and appeal.

Startup, Technology & Venture Law

Startup, Technology & Venture Law

From day-one formation through Series financings and exit, Grellas Shah counsels San Francisco startups through the full arc of company-building. We handle entity structure, equity, SAFEs, priced rounds, contracts, IP, and M&A — with the attention only a boutique can provide.

Founder & Shareholder Disputes

Founder & Shareholder Disputes

Founder disputes are among the most damaging events a startup can face. When co-founders disagree on direction, equity, or control — or when boards and management end up at odds — we bring rare startup fluency combined with real litigation muscle.

Trade Secret & IP Litigation

Trade Secret & IP Litigation

San Francisco’s economy runs on ideas — and the fights that erupt when they’re copied or stolen. We litigate trade-secret misappropriation, employee-mobility disputes, technology and copyright claims, and complex IP matters on both plaintiff and defense sides.

Corporate, Contracts & M&A

Corporate, Contracts & M&A

Entity formation, corporate governance, commercial contracts, licensing, joint ventures, financings, and M&A from term sheet through closing. Whether inking a partnership, closing a Series A, or selling the company, we handle it end-to-end.

Employment, Securities & Regulatory

Employment, Securities & Regulatory

Executive-level employment disputes, stock-option litigation, securities claims, and regulatory inquiries. Grellas Shah has counsel and courtroom experience across the full spectrum of business-related matters SF companies encounter.

WHY GRELLAS SHAH

Big-Firm Experience. Boutique Focus.

Chambers & Partners Recognized

Ranked in the Chambers & Partners Spotlight California 2026 guide for Litigation: General Commercial — the international benchmark for law firm rankings.

AmLaw Experience, Boutique Scale

Our partners built their trial and transactional records at leading AmLaw firms before founding Grellas Shah. San Francisco clients get big-firm caliber work with the direct partner attention only a boutique offers.

Founder-Focused, Conflict-Free

Unlike large firms tied to every VC and later-stage acquirer, we maintain a founder-focused practice free of divided loyalties. When we represent a startup, we represent the startup.

CLIENT VOICES

What San Francisco Founders & GCs Say

Grellas Shah delivered big-firm caliber legal work without the big-firm bureaucracy. Our partner was personally involved on every substantive issue — and the outcome exceeded what we expected.

CEO, Series A Startup, SoMa

FAQ

Frequently Asked Questions

What kinds of San Francisco clients does Grellas Shah typically represent?
Startups from pre-seed through late-stage growth, technology companies of every size, founders and executives, investors and VCs, and closely-held businesses. On the litigation side, we represent businesses, founders, executives, and investors in complex commercial disputes throughout SF and the Bay Area.
What makes Grellas Shah different from a large San Francisco law firm?
Two things. Our partners have AmLaw-caliber experience but practice at boutique scale, so senior lawyers actually work on your matter. And we’re a founder-focused firm free of conflicts with the largest VCs and later-stage acquirers, which lets us represent early-stage clients without divided loyalties.
Do you handle both litigation and transactional startup work?
Yes. Our two anchor practices are complex business litigation and startup, technology, and venture law. We handle formation, financings, and M&A on the transactional side, and pre-litigation strategy through trial and appeal on the disputes side.

550 California Street, Suite 1040, San Francisco, CA 94104 — in the Financial District. We also have an office in New York (447 Broadway, 2nd Floor #576).
