Expert legal counsel can be the difference between whether your startup thrives or sinks.
Over the past 15 years, I’ve worked with hundreds of startup founders for their business valuation needs and have connected them with reliable and highly experienced legal firms in the U.S.
To help you find the best startup law firms, I analyzed Pitchbook Data—a private capital market and research database—and selected 20 law firms particularly suitable for startups.
For each firm, I’ll describe:
While the number of deals and companies served doesn’t guarantee they’re great for every startup, it does show they have experience and expertise in specific fields.
Also, my own experience with some of the firms on the list indicates that they are trustworthy and reliable for startups seeking legal guidance.
However, please note that the information I’ll present does not constitute an endorsement of any specific firm. You should always conduct your own due diligence before selecting legal counsel.
Pitchbook Data, with its extensive VC and startup investment database, can help identify suitable law firms for startups. It tells you:
However, relying only on metrics like deal numbers and companies served to find the “best” firm has both benefits and limitations.
While Pitchbook Data offers valuable insights, relying solely on its metrics for a definitive “best” firm presents an incomplete picture. Consider these additional factors:
Pitchbook Data provides a helpful starting point, but the “best” law firm for your startup is a subjective decision.
Use the data, but go beyond numbers, delve into firm culture, individual experiences, and alignment with your unique needs to find the true legal partner for your venture’s success.
Based on Pitchbook Data for calendar year 2023, I selected 20 top law firms for startups, sorted by number of venture capital deals above $2.0 million during the calendar year.
