Practice

Practice Areas

Accurate map of the United States and Puerto Rico

We've managed cases with over $1 billion in controversy across the country, in courts and arbitrations across the country, ranging from California to Wyoming, New York, Puerto Rico, federal court, state court, and arbitration. Our firm already has active cases in half a dozen+ jurisdictions in state and federal courts around the nation, including California and New York.

01

Technology litigation

We represent innovative companies building the future of AI, crypto, and other emerging technologies, as well as individuals and organizations righting wrongs done by more resourced adversaries. Our team has done over 8 TROs in the last year and a half and are no strangers to crises. We deal with competitors, unauthorized access, competitor antitrust disputes, and unfair competition.

02

Crypto

We pioneered many areas of crypto litigation over the years, including partnership theories related to DAOs, temporary and preliminary injunctive relief, and alternative service on the blockchain. We’ve recovered over $250M in stolen crypto.

We’ve represented high-net-worth investors, top DeFi projects, and startups. We’ve fought against market manipulation. We’ve handled DOJ investigations, CFTC investigations, and SEC investigations. When the exchanges do wrong, we’re not shy about going after them. We have active cases against Aave, OKX, Coinbase, and others.

We’ve done defamation cases in crypto based on online trolling. We’ve done incident response, and we understand the technology. We know how to persuasively craft winning strategies for judges and fact-finders.

03

Defamation

We’ve represented billionaires, celebrities, businesses, and founders in defamation, Lanham Act, and other cases all around the country. We’ve been on both sides of it. We have extensive experience with anti-SLAPP in state and federal courts nationwide.

04

Founder and investor disputes

We’ve done M&A gone bad, earn-out disputes, and founder splits. We’re very good at resolving these disputes before they get to filing. Mike was a former CEO and founder and has been on that side of the table. We know the challenges founders face. We’ve represented private equity firms, startups, founders, and major venture capital firms.

05

Class actions

We’ve prosecuted class actions against Fortune 500 companies all over the country. Our cases typically involve fraud, electronic privacy violations, pollution, or other corporate misconduct.

This includes:

  • Consumer fraud matters about pharmaceuticals, insurance, climate deception, collecting illegal fees, credit card/payment processing rules, and software licenses.
  • Electronic privacy matters about illegal collection of health data, overuse of tracking technology, and other forms of illegal data collection.
  • Public nuisance cases about pollution, environmental disasters, greenwashing, and opioid addiction.

06

Arbitration

In or outside of Court, we can develop trial strategies geared towards finders of law and fact. We have experience with JAMS, AAA, mass-arbitration, and international arbitration.

07

Regulatory

The firm provides regulatory advice in areas of crypto, AI, and privacy. We know how to develop and handle regulatory investigations. We’ve gone up against federal and state regulators. We’re not afraid to sue the government, and we’re also able to settle. We have a track record of getting investigations closed, whether they are brought by the Department of Justice, Securities and Exchange Commission, Commodities Futures Trading Commission, or others. We also know how to help crime and market manipulation victims cooperate with regulators to pursue justice.

08

Incident response

Mike has managed some of the largest data breaches and ransomware attacks. Mike has handled dozens of incidents, small, medium, and large, ranging from startups to Fortune 500 companies. We know how to work with the DOJ, FBI, and global law enforcement in the immediate aftermath and for the long haul. Mike has dealt with massive software thefts from the technology industry and successfully executed worldwide rapid takedown campaigns.

09

Curated Corporate Practice

Mike has 10+ years of experience as a fractional General Counsel. His clients have done hundreds of millions in financing, acquired businesses, sold to public and private companies, and gone through the entire gauntlet of the startup roller coaster. As a former CEO & Founder, Mike knows how annoying it is to deal with corporate lawyers. We can’t promise not to be annoying, but we try.

We represent a rarefied portfolio of AI startups, enterprise startups, and consumer startups, individual investors, and venture capital firms. Some of the best founders in the world trust us to manage their legal roadmap.

Bottom line: If it’s hard, we want to do it. If you’re in a fight, we want to be on the frontlines. If you need to broker peace, we know how to do that too.

Technology

Technology

We are technical lawyers. Our team knows how to code. Even before AI, enough to be dangerous. Mike was the CEO of an engineering-focused company and developed software for the Air Force, top banks, media companies, and the Department of Homeland Security. Jacob worked for technology companies before law school and draws on that knowledge when litigating e-privacy, advertising fraud, and other cases involving online businesses. We bring technical precision to our legal work.

We’ve been on the leading edge of AI adoption. Mike has taught AI law at UC Berkeley. He has represented leading innovators in AI, machine learning, and large language models in matters involving copyright, right of publicity, and privacy.

Mike first adopted o3 in Spring 2025 and was blown away by the power of a reasoning model. He used it at trial to great success. He’s dug in with every step-change in capability, including leaning into coding harnesses late last year. Like everyone else, Mike spent his 2025 holidays playing with Claude Code. He developed a custom orchestrator with Codex driving across models, developed an adversarial review system, and has innovated anti-hallucination technologies. He’s built systems that change how clients digest case updates, the management of discovery, preparation for hearings, brief revisions, and trial.

We don’t think AI is a robot. It is a suit of armor. We use it to gain leverage for our clients.

We’re committed to passing on the remarkable benefits of the current moment the world finds itself in to our clients. We believe that the barriers to litigate cases are going down. We do not think armies are necessary anymore, and that the practice of law will return to a mentorship model of a small group of lawyers that will fight for their clients in court. More cases will go to trial.

With our clients, we are innovating the practice of law itself.

“Outstanding closing remarks. I can’t describe what you guys have left me to deal with. It’s indescribable, as a matter of fact. They don’t prepare you in law school to handle a case like this.”

Jacob Polin

02 / Founding Partner

Jacob Polin

jacob@burshteynpolin.com

Jacob specializes in helping victims of fraud recover losses from powerful opponents. He represents consumers, small businesses, startups, founders, and investors in all manner of disputes involving deceptive business practices, cyber security failures, unfair competition, and privacy violations. For many years, nearly all of his representations have been on a contingency (percent of recovery) fee basis. Eschewing hourly payment structures helps him and his clients focus on the actual value of their cases, and improve access to justice.

In his practice, Jacob often represents large groups. These cases can be organized as class actions, mass actions, or cases brought by public entities, such as cities, counties, or Native American tribes. For example, he and his former colleagues at Lieff Cabraser Heimann & Bernstein, LLP obtained a $230 million recovery for the People of San Francisco in opioid litigation, winning the Daily Journal's “California Lawyers of the Year” award in 2023. In another case brought on behalf of victims of the 2015 Refugio Oil Spill in Santa Barbara, they obtained a $200 million settlement from a large publicly-traded oil company shortly before trial. He also litigated similar cases against other large technology, financial, cryptocurrency, insurance, oil, and chemical companies.

Jacob enjoys working with clients, experts, and colleagues to learn how different industries function and the conditions that give rise to fraud. He tries to bring a nuanced perspective to that analysis, as an attorney who previously represented large corporations at Quinn Emanuel Urquhart & Sullivan, LLP. In privacy and advertising-related litigation, he also draws on his pre-law school experience as a digital media buyer for technology companies and progressive political campaigns.

Jacob grew up in Oakland, California. His first five years of education were primarily in French, which he speaks fluently. He earned his Bachelor of Arts in History and Political Science at the University of California at Berkeley in 2011. While there, he and Mike Burshteyn led Cal to win the Copeland Award for the #1 ranked Two-Person Debate Team in the United States. Jacob earned his Juris Doctorate cum laude from Northwestern University School of Law in 2016. While there he was also named a “Public Service Star.”
