Startup.Law

What Startup.Law does

Startup.Law is a New York-based boutique legal services brand operated by Masur Griffitts Avidor LLP (MGA), a limited liability partnership formed in 2019 through the merger of Masur Griffitts LLP, Avidor Law PC, and the Startup.Law legal blog. The firm provides transactional and corporate legal counsel to early-stage, growth-stage, and enterprise-stage companies, as well as to venture capital firms and investment funds, across the full company lifecycle from formation to exit. Its service repertoire spans corporate formation and governance, SAFE notes, convertible notes and priced equity financings, mergers and acquisitions, employment and executive compensation, fund formation, commercial contracts, licensing, real estate private equity, and specialized regulatory advice in blockchain, cryptocurrency, and cannabis.

The underlying delivery model is a partner-led professional services practice with three named attorneys: Steve Masur (25+ years of experience advising emerging-industry clients, recognized as a "Rising Star" and "Super Lawyer"), Rob Griffitts (20+ years focused on VC financings, M&A, and crypto/ICO structuring), and Jon Avidor (JD-MBA from Northwestern; prior tenure at Sullivan & Cromwell and Goodwin Procter; founder of the Startup.Law blog and Avidor Law PC). There is no proprietary technology platform; the core offering is human legal counsel delivered through direct client engagement.

Revenue is generated via professional services fees structured as flat fees or monthly subscriptions rather than traditional hourly billing — a deliberate positioning choice to accommodate startup and VC client budgets. Distribution is sales-led, driven by professional reputation, network referrals, content marketing through the Startup.Law blog (covering Company Formation, Employment Issues, Financing/Taxes, and Intellectual Property), and direct outreach. The firm reports operating geographies in the Northeast US and West Coast/Silicon Valley, with named historical enterprise clients including Shazam, Virgin Mobile, Liberty Media, Yamaha, Diageo, Warner Music Group, Conde Nast Publications, Nielsen Buzzmetrics, and Bob Vila.

Direct peers

• Cooley LLP: Major law firm with one of the largest technology and emerging companies practices. Competes with Startup.Law for the same startup founder and VC clients across financings, M&A, and corporate governance work.
• Fenwick & West: West Coast-based firm with deep technology and venture capital focus. Competes directly with Startup.Law for startup and VC mandates, particularly in Silicon Valley where Startup.Law also operates.
• Gunderson Dettmer: Leading boutique law firm focused on venture capital and emerging companies. Directly comparable to Startup.Law in target client base (VCs and high-growth startups) and core practice areas (financings, M&A, fund formation), but at significantly greater scale.
• Mintz: Mid-size firm with an active venture and emerging companies practice. Serves similar startup and investor clients across financings, fund formation, and general corporate matters.

Others

• Sullivan & Cromwell: Elite global law firm where Startup.Law co-founder Jon Avidor previously practiced. Relevant as a talent pipeline and as an incumbent competitor on larger M&A and capital markets transactions.

Broad incumbents

• Orrick Herrington & Sutcliffe: Global law firm with a substantial emerging companies and venture capital practice. Competes for the same startup and VC mandates Startup.Law targets, while also serving larger enterprise clients across additional practice areas.
• Goodwin Procter: Large, full-service firm with a leading technology and life sciences practice. Directly competes for VC-backed company mandates and IPO/M&A work, while also offering broader corporate capabilities Startup.Law cannot match.
• Wilson Sonsini Goodrich & Rosati: Premier technology and life sciences firm historically associated with Silicon Valley. Represents the same venture-backed startup and VC client base, offering Startup.Law's specialty work alongside much broader transactional and litigation capabilities.
• Latham & Watkins: Global full-service firm with a strong emerging companies and venture capital practice. Engages on the same formation-to-exit lifecycle matters Startup.Law handles, but with vastly greater bench depth and international reach.

Emerging players

• Founders Circle Capital Legal: Boutique advisory and legal services provider targeting early-stage founders. Comparable to Startup.Law in targeting startup clients with bundled, budget-friendly offerings, though structured more as an accelerator-adjacent service than a full law firm.
