ZwillGen Washington Office

Leaving behind big law bureaucracy has allowed us to focus on one thing—delivering high value legal advice to help our clients make the most of new technologies.

We have built a strong practice counseling leading Internet and tech companies and handling their high profile online legal issues. 

Some of the biggest names in technology rely on us to respond to and resolve their most serious legal challenges. They turn to us because we are knowledgeable, cost-effective, and while we do serious work, we don’t take ourselves too seriously.

We’re proud to admit we’re not just legal brains; we’re tech geeks too. We live and breathe technology. That’s why we can react faster, smarter, and better than the competition. We know the ins and outs of your business as well as we know Internet law. And the combination is unbeatable.

Our History

What began in 2010 as a big idea in a small Washington, DC row house has become a thriving coast-to-coast law firm with nearly thirty attorneys and fourteen staff members spread over four offices in Washington, DC, New York, Chicago, and San Francisco.

Founded in 2010 by Marc Zwillinger and Christian Genetski, Zwillinger Genetski LLP was known for its pioneering, anti-Big Law spirit and practical advice. In 2011, Zwillinger Genetski LLP began to grow and was rebranded as ZwillGen PLLC. By 2014, ZwillGen outgrew its Dupont Circle row house and moved a few blocks away to its current home at 1900 M Street NW.

In 2016, ZwillGen opened its California Subsidiary, ZG Subpoena Solutions, to help clients process third-party data requests. That same year, Managing Member and Founder Marc Zwillinger became known as “Apple’s Secret Weapon” for his representation of the company in Apple v. San Bernardino.

Today, ZwillGen continues to be known for its pioneering spirit and practical advice as it helps clients both big and small in a wide range of industries tackle emerging technology and data-related legal issues.

Billing Philosophy

We believe the existing hourly law firm model is outdated and misaligns the interests of lawyers and their clients.
 
Law firms should be rewarded for helping clients efficiently solve problems and discouraged from spending more time than necessary to achieve the same result.
 
That’s why we have alternative pricing models. On every matter, our goal is to find the right pricing structure to align our incentives with your success.

  • 1

    Monthly Retainers

    We handle all of the legal work in a given area or subject matter for a monthly retainer, which we can adjust upward or downward as the work ebbs and flows.

  • Flat Rate/Project Fees
    2

    Flat Rate/Project Fees

    Under this model, we take the risk that we have underestimated the time that needs to be spent. If it takes longer, you still don’t pay any more. If we are very efficient, we get the benefit of our efficiency.

  • Success Fees
    3

    Success Fees

    Even in the simplest matters, like creating Terms and Conditions for a website, you know how to measure success, and we want to deliver that result. Accordingly, you pay us a reasonable rate or fee for the work and agree on an additional fee to be paid if we are successful, however you decide to define it.

  • One Rate Hourly Pricing
    4

    One Rate Hourly Pricing

    Because we work collectively to solve your problems, nearly all of our lawyers are available for the same rate, except our Fellows. Our Fellows are one or two years out of law school and we bill them at half the price of an experienced attorney. They are perfect for those legal tasks you don’t want to pay a 20-year legal veteran to do, but that are more sophisticated than what a paralegal should be doing.

Our Culture

At ZwillGen, we like the work we do and we like each other. We take our work seriously, but we don't take ourselves too seriously.
