Gesmer Updegrove LLP

The Firm

Gesmer Updegrove LLP is a Boston-based law firm serving technology companies, emerging growth businesses, middle-market companies, investors, founders, executives, boards, universities, industry consortia, open source foundations, financial services firms, and innovation-driven organizations. Founded in 1986, the firm was built around a core idea that remains central to its identity today: sophisticated companies need sophisticated legal counsel, but they also need lawyers who understand how businesses actually operate.

Gesmer combines the technical depth and judgment expected from a national law firm with the focus, accessibility, and commercial practicality of a partner-led platform. The firm is regularly called upon to advise clients at critical moments in their lifecycle, including formation, financing, strategic growth, acquisitions and exits, governance disputes, regulatory scrutiny, internal investigations, intellectual property protection, and high-stakes commercial disputes.

The firm’s clients operate across some of the most dynamic and heavily scrutinized sectors of the economy, including technology, software, SaaS, fintech, blockchain, digital assets, financial services, cannabis, life sciences, standards development, open source, data, artificial intelligence, consumer products, and professional services. Gesmer’s work often sits at the intersection of corporate strategy, technology, intellectual property, capital formation, regulation, and dispute resolution.

In 2026, Gesmer Updegrove earned national recognition from The Legal 500 United States in four practice areas: Corporate Investigations & White Collar Crime, Tier 3; Finance: Fintech, Tier 4; IP: Trademark: Non-Contentious, Tier 3; and M&A: Middle-Market, Tier 5. For a firm of Gesmer’s size, these rankings are significant. Legal 500 rankings are competitive national rankings based on market research, client feedback, representative matters, and comparative assessment against peer firms, including many substantially larger national and global platforms. Gesmer’s recognition reflects the firm’s ability to compete in sophisticated national categories while maintaining a focused, senior-led model.

Corporate, M&A, Venture Capital, and Emerging Companies

Gesmer has long been known for its work with entrepreneurs, emerging companies, middle-market businesses, investors, and strategic acquirers. The firm advises clients across the full business lifecycle, from formation and early-stage financing through growth, governance, strategic transactions, acquisitions, recapitalizations, and exits.

The firm’s Corporate and M&A practice represents buyers, sellers, investors, management teams, private equity sponsors, venture capital firms, public companies, and strategic acquirers in domestic and cross-border transactions. Its work includes stock and asset acquisitions, mergers, platform acquisitions, add-on transactions, roll-up strategies, minority investments, preferred equity financings, convertible instruments, venture capital rounds, private equity transactions, corporate restructurings, and founder-led exits.

Over the last several decades, Gesmer has handled more than $6.2 billion in early and emerging-stage M&A transactions and more than $5.4 billion in venture capital and private equity financing transactions, and has served more than 6,000 corporate and investor clients. The firm’s transactional lawyers regularly manage deals involving complex governance rights, intellectual property ownership, data rights, commercial agreements, earn-outs, multi-class equity structures, cross-border considerations, tax structuring, regulatory constraints, and operational transition issues.

Gesmer’s corporate clients include emerging companies and established businesses alike, including companies backed by venture capital, private equity, strategic investors, founders, and family ownership structures. The firm’s client base has included leading technology companies, universities, software companies, standards organizations, public companies, cannabis operators, investors, and high-growth businesses. Representative clients and matters reflected in the firm’s submissions include Curaleaf Holdings, Inc., Massachusetts Institute of Technology, Harvard University, Rapid7, Berkshire Grey, the World Wide Web Consortium, the Linux Foundation, Long Angle, PCI Security Standards Council, Canton Foundation, and other sophisticated organizations.

A defining feature of Gesmer’s corporate practice is its ability to pair deal execution with long-term business judgment. Many clients work with the firm through multiple stages of growth, giving Gesmer deep institutional knowledge of the client’s business, capitalization, governance, contracts, commercial relationships, and strategic objectives. That continuity allows the firm to deliver practical, efficient advice when clients face transformative transactions or complex business inflection points.

Technology, Standards, Consortia, and Innovation

Gesmer occupies a distinctive position in the technology and standards-development ecosystem. The firm was co-founded by Andrew Updegrove, an internationally recognized pioneer in what is now known as consortium law. The firm has helped form and represent standards-setting organizations, industry consortia, open source foundations, and collaborative technology ventures across a broad range of industries.

Gesmer has represented more standards consortia than any other domestic or foreign law firm, and has represented such entities in scores of M&A, governance, intellectual property, and technology-related matters. The firm’s clients include major standards bodies and open source organizations whose members include thousands of technology companies, including many of the world’s largest technology enterprises.

This background gives Gesmer unusual experience with multi-party governance, intellectual property policy, antitrust-sensitive collaboration, open source strategy, licensing structures, international stakeholder negotiations, standards adoption, and complex organizational design. That experience also informs the firm’s broader technology practice, including its work with startups, software companies, digital infrastructure providers, fintech companies, blockchain foundations, and technology-enabled businesses.

Securities Regulation, Financial Services, Fintech, and Digital Assets

Gesmer’s Securities Regulation & Financial Services and Securities Enforcement and Investigations practices expand the firm’s platform into areas of increasing importance to technology, fintech, digital asset, financial services, and investment management clients. The firm advises clients on securities enforcement, financial services regulation, investment adviser compliance, broker-dealer issues, alternative trading systems, fintech-bank partnerships, money transmission, digital assets, tokenized securities, custody, market structure, AML/KYC, and regulatory investigations.

The firm represents investment advisers, fintech companies, digital asset businesses, broker-dealers, startups, founders, executives, boards, and special committees in matters involving the SEC, FINRA, CFTC, DOJ, state securities regulators, state attorneys general, and other federal and state agencies. Its work includes SEC investigations, state securities investigations, SEC examinations, Enforcement referral risk, internal investigations, regulatory response strategy, disclosure issues, fiduciary duties, supervision failures, conflicts, books and records, digital asset products, automated advisory platforms, tokenized securities, and crypto-related regulatory risk.

The firm’s fintech work includes advising companies on Money Services Business status, FinCEN registration, state money transmitter licensing, sponsor-bank arrangements, flow-of-funds architecture, FBO and omnibus accounts, safeguarding of customer funds, BSA/AML compliance, OFAC screening, transaction monitoring, vendor oversight, examination readiness, and regulatory risk allocation. Gesmer also advises on broker-dealer formation, digital asset custody, Special Purpose Broker-Dealer issues, alternative trading system strategy, Rule 15c2-11, DTC eligibility, secondary trading, securities token classification, resale restrictions, and platform eligibility.

This practice is closely aligned with Gesmer’s historic technology and emerging companies platform. Many of the firm’s clients operate in sectors where regulatory questions arise early and can shape the business model itself. Gesmer’s ability to combine corporate, technology, intellectual property, and regulatory counsel allows the firm to advise clients not only on what the law requires, but on how to structure products, governance, relationships, disclosures, and commercial strategy in a way that supports durable growth.

Corporate Investigations, White Collar, and Government Enforcement

Gesmer’s Corporate Investigations & White Collar Crime practice represents companies, boards, special committees, executives, founders, financial institutions, investment advisers, fintech companies, digital asset businesses, and other clients in sensitive investigations, enforcement matters, internal reviews, and enforcement-adjacent litigation.

The firm advises clients in matters involving securities fraud, disclosure issues, investment adviser regulation, fiduciary duties, conflicts of interest, supervision failures, market conduct, insider trading, digital asset issues, executive misconduct, governance breakdowns, financial misconduct, embezzlement, fraud, whistleblower allegations, and parallel regulatory exposure. Gesmer’s lawyers conduct internal investigations designed to withstand government scrutiny while helping clients make practical decisions about remediation, disclosure, governance, discipline, and risk mitigation.

The practice includes experience before the SEC, DOJ, FINRA, CFTC, state securities regulators, state attorneys general, and law enforcement agencies. Gesmer also advises clients in digital asset theft, blockchain tracing, cyber-enabled fraud, incident response, platform preservation requests, law enforcement coordination, and cross-border crypto fraud matters.

The firm’s investigations approach is practical, discreet, and strategically focused. Gesmer’s lawyers work to understand the business context, preserve privilege, establish a disciplined factual record, identify legal and reputational risk, and position clients for the best available outcome, whether that means avoiding enforcement action, narrowing exposure, supporting remediation, managing parallel proceedings, or preparing for litigation.

Intellectual Property, Trademark, and Technology Transactions

Gesmer’s intellectual property practice supports clients whose value is closely tied to brands, technology, software, data, creative assets, proprietary systems, and commercial relationships. The firm advises on trademark strategy, brand protection, clearance, prosecution, portfolio management, licensing, technology transactions, software agreements, SaaS arrangements, development agreements, commercial contracts, open source issues, intellectual property ownership, data rights, and commercialization strategies.

The firm’s IP work is closely integrated with its corporate, technology, M&A, and standards practices. Gesmer regularly advises clients on IP issues arising in financings, acquisitions, strategic partnerships, licensing arrangements, standards development, consortium governance, software commercialization, and business expansion. That cross-disciplinary model allows the firm to help clients protect core assets while also using intellectual property as a practical tool for growth, defensibility, and commercial leverage.

Litigation and Dispute Resolution

Gesmer represents companies, founders, investors, executives, boards, and technology-driven businesses in commercial disputes, governance conflicts, employment-related disputes, securities-related litigation, intellectual property disputes, founder disputes, contract claims, business torts, regulatory-adjacent litigation, and disputes involving sensitive reputational issues.

The firm’s litigation approach emphasizes early case assessment, business-focused strategy, disciplined discovery, motion practice where appropriate, and practical resolution when a negotiated outcome better serves the client’s objectives. Gesmer’s litigators work closely with the firm’s corporate, regulatory, IP, employment, and technology lawyers, allowing the firm to handle disputes with a full understanding of the client’s business structure, financing history, governance rights, commercial relationships, and long-term objectives.

A Partner-Led Platform for Sophisticated Clients

Gesmer’s model is built around senior attention, practical judgment, and durable client relationships. The firm is large enough to handle sophisticated transactions, investigations, financings, regulatory matters, IP portfolios, and disputes, but focused enough to deliver direct partner involvement and tailored advice.

Clients come to Gesmer when they need lawyers who can move quickly, understand complexity, and provide advice that is legally sound and commercially useful. The firm’s lawyers are accustomed to advising clients in situations where legal, business, regulatory, technological, and reputational considerations overlap.

Gesmer’s platform is particularly well suited to clients operating in markets shaped by innovation, regulation, and rapid change. The firm has built nationally recognized practices in areas that are central to the modern economy: emerging companies, M&A, venture capital, technology, standards, open source, fintech, digital assets, financial regulation, investigations, IP, and high-stakes disputes.

At its core, Gesmer is a firm for builders, innovators, investors, boards, and companies navigating consequential moments. Its lawyers help clients form, finance, protect, scale, regulate, defend, acquire, sell, and transform businesses. That combination of corporate depth, technology fluency, regulatory sophistication, and partner-led execution is what defines Gesmer Updegrove.
