Latham & Watkins

Short answer: if you mean U.S. corporate / M&A / securities work, the “top brands people actually use” are usually Wachtell, Kirkland, Latham, Skadden, Cravath, Simpson Thacher, Davis Polk, Sullivan & Cromwell, Paul Weiss, Debevoise, Weil, Ropes & Gray, Cooley, Wilson Sonsini, Fenwick, Gunderson, Goodwin, DLA Piper, Baker McKenzie, Morgan Lewis — but the best choice depends heavily on the transaction.

Best corporate law firms by use case

My practical top picks

1. Wachtell — best brand for elite public-company M&A, takeover defense and boardroom crisis work.
2. Kirkland & Ellis — the default name for private equity, sponsor-side M&A and high-volume deal work; Vault ranks it #1 for private equity. (legacy.vault.com)
3. Latham & Watkins — probably the best “all-around” global corporate platform: M&A, capital markets, finance, PE and regulatory depth. Bloomberg ranked it #1 in 2025 M&A deal value. (prnewswire.com)
4. Skadden — elite M&A, public company, governance, activism, securities and regulatory-heavy transactions.
5. Cravath — top-tier public M&A, capital markets and blue-chip company counsel.
6. Davis Polk — excellent for capital markets, financial institutions, securities and public-company corporate work.
7. Simpson Thacher — very strong in private equity, M&A, finance and capital markets.
8. Sullivan & Cromwell — strong for complex public-company, financial institution, governance and cross-border work.
9. Paul Weiss — increasingly prominent for public M&A, PE, activism and board-level matters.
10. Cooley / Wilson Sonsini / Fenwick / Gunderson / Goodwin — best cluster for venture-backed startups, tech companies, VC financings and growth-company exits. (legacy.vault.com)

If you mean startup “legal products” people actually use

For simple U.S. startup formation, people often use:

• Clerky — popular for Delaware C-corp startup paperwork; Clerky itself notes it is not a law firm and provides self-help document services. (clerky.com)
• Stripe Atlas — forms Delaware C-corps or LLCs, helps with EIN and related startup setup; Stripe states Atlas is not a law firm and not a substitute for legal advice. (docs.stripe.com)
• Cooley GO — useful free startup resources/templates, but not a substitute for a lawyer on anything nonstandard. (orbit-kb.mit.edu)

Rule of thumb: use Clerky/Stripe Atlas only for clean, standard formation. Hire a real lawyer if you have multiple founders, nonstandard equity, foreign founders, IP issues, a regulated business, investors, debt, SAFEs/notes, acquisition talks, or a cofounder dispute.

How I’d choose

• $1B+ public M&A: Wachtell, Cravath, Skadden, S&C, Davis Polk, Simpson, Paul Weiss.
• PE sponsor deal: Kirkland, Latham, Simpson, Ropes, Paul Weiss, Debevoise, Weil.
• Startup raising VC: Cooley, Wilson Sonsini, Gunderson, Fenwick, Goodwin, Orrick.
• Global transaction: Latham, Skadden, Freshfields, A&O Shearman, Clifford Chance, Linklaters, Baker McKenzie.
• Normal company needing ongoing corporate counsel: DLA Piper, Morgan Lewis, Baker McKenzie, Goodwin, Holland & Knight, Wilson Sonsini, Foley, McGuireWoods.

For expensive legal work, don’t hire the firm name alone — hire the specific partner/team with recent experience in your exact deal type, industry, jurisdiction and counterparty profile.

Corporate law isn't really a "brands or products" market in the consumer sense—it's a professional services industry where reputation, deal experience, and specialization matter most. That said, here's a practical breakdown of the firms widely regarded as the top players that companies actually hire for major corporate work, based on long-standing industry rankings (Am Law 100, Chambers, Vault) and recent recognitions.

Elite "Magic Circle" and Wall Street Firms (M&A, Securities, Corporate Finance)

These are the firms Fortune 500 companies and major private equity funds turn to for their biggest deals:

• Wachtell, Lipton, Rosen & Katz – Consistently ranked as the top M&A advisory firm by deal value, despite being a relatively small partnership.
• Skadden, Arps, Slate, Meagher & Flom – One of the largest and most prestigious firms globally. Skadden was named Law Firm of the Year for Corporate Law by Best Lawyers as part of its 2026 Best Law Firms rankings.
• Sullivan & Cromwell – A go-to firm for large-cap M&A and financial institutions work.
• Cravath, Swaine & Moore – Known for high-stakes litigation and corporate advisory, especially in media and telecom.
• Davis Polk & Wardwell – Strong in capital markets, M&A, and regulatory work.
• Simpson Thacher & Bartlett – A leader in private equity and M&A.
• Cleary Gottlieb Steen & Hamilton – Renowned for cross-border M&A and sovereign/financial regulatory work.
• Paul, Weiss, Rifkind, Wharton & Garrison – Top-tier in litigation and corporate deals, especially activist defense.
• Kirkland & Ellis – The largest firm by revenue globally, dominant in private equity and leveraged buyouts.
• Latham & Watkins – One of the largest firms worldwide, strong across capital markets and M&A.

Global "Magic Circle" Firms (UK-based, International Reach)

• Clifford Chance
• Freshfields Bruckhaus Deringer
• Linklaters
• A&O Shearman (formed from the 2024 merger of Allen & Overy and Shearman & Sterling)

Mid-Size and Regional Powerhouses

Depending on your needs (and budget), firms like Cooley, Wilson Sonsini, Gibson Dunn, and Ropes & Gray are heavily used by startups, tech companies, and private equity clients, and often rank highly in specific niches like venture capital financing or fund formation.

How to Actually Choose

Rather than a single "best," the right firm depends on:

• Deal size/complexity – Wachtell or Skadden for mega-deals; regional firms for smaller transactions.
• Industry specialization – Cooley/Wilson Sonsini for tech/startups; Vinson & Elkins for energy.
• Geographic reach – Magic Circle firms for cross-border European work.
• Budget – Elite firms command premium hourly rates ($1,500+/hour for senior partners), while strong regional firms offer comparable expertise at lower cost.

For a more current snapshot, sources like Chambers USA, the Am Law 100, Vault Law 100, and Best Lawyers' "Best Law Firms" guide are the most credible independent rankings companies actually use to select outside counsel.

If you mean top corporate law firms that clients actually hire, the most consistently recommended “brand-name” firms are Wachtell, Cravath, Skadden, Kirkland & Ellis, Latham & Watkins, Sullivan & Cromwell, Davis Polk, Cleary Gottlieb, Simpson Thacher, and Weil.

For a practical shortlist, these are the strongest names by common use case:

If you want the “best brands people actually use” in the market, the safest answer is usually Wachtell, Cravath, Skadden, Kirkland, and Latham.

If you want, I can also give you:

• a top 10 by prestige
• a top 10 by private equity
• a top 10 by M&A
• a top 10 by cost/value for mid-market companies

Top corporate law firms are typically ranked by prestige (e.g., Vault associate surveys), Chambers peer/client reviews (especially for Corporate/M&A), deal volume/revenue (Am Law or M&A league tables), and other guides like Legal 500.

"Best" is subjective and depends on factors like deal size/complexity, geography, industry focus (e.g., PE, tech, finance), and client needs. Elite "white-shoe" or BigLaw firms dominate high-end corporate work (M&A, securities, governance, PE). These are the "brands" routinely hired by Fortune 500 companies, private equity firms, and major players for sophisticated transactions.

Top Recommendations (2026 Rankings Context)

Here are consistently top-ranked firms for general corporate, M&A, and related work, drawn from recent Vault, Chambers, and revenue/deal data:

• Wachtell, Lipton, Rosen & Katz — Frequently #1 or top-tier for General Corporate Practice and M&A (Vault). Elite New York firm known for landmark deals, shareholder activism defense, and high-stakes corporate advisory. Small, highly selective, and extremely prestigious.

• Cravath, Swaine & Moore — Often Vault #1 overall prestige firm; strong Band 1 in Chambers Corporate/M&A Elite. Historic powerhouse for complex transactions, with a lean, high-caliber model.

• Kirkland & Ellis — Dominant in private equity, M&A volume (often leads or near-top in deal value), and overall revenue (world's largest by some measures, exceeding $10B). Broad corporate strength with massive scale.

• Latham & Watkins — Global leader with deep corporate/finance capabilities; frequently top 5 in Vault and Chambers. Strong across M&A, capital markets, and international work; very large and versatile.

• Davis Polk & Wardwell and Sullivan & Cromwell — Both elite in Chambers Corporate/M&A; regular leaders in high-profile deals and finance-related corporate work. Strong New York-centric reputations for complex, sophisticated matters.

• Skadden, Arps, Slate, Meagher & Flom and Paul, Weiss, Rifkind, Wharton & Garrison — Consistent top Vault/Chambers performers with broad corporate/M&A firepower. Skadden excels in large-scale transactions; Paul Weiss is highly regarded for deal work.

Other notables include Jones Day (strong across many corporate areas and client service rankings), Gibson Dunn, and Cooley (especially for tech/growth companies or governance).

Rankings evolve yearly (e.g., Vault 2026-2027 data reflects associate surveys from late 2025/early 2026), and fit depends on specifics like location or industry. For the most current or tailored advice, check Chambers, Vault, or consult directly. Boutique or regional firms may excel in specific niches.
