Startup Legal Services Done Right

Greg Karch and Brent Britton have both long envisioned a law firm specifically built for start-ups. A firm geared towards the realities of the start-up process. They have both been in the trenches and built the foundations of successful businesses. They understand the process. With CoreX Legal, Greg and Brent bring together years of experience and a casual, friendly, laid back approach to lawyering start-ups. “We get the dream and we’re committed to helping you realize yours.” And they’ve built a team of lawyers and business advisors who are here to fuel your dreams.

Why CoreX … It all comes down to the CoreX Difference!

  • Some law firms work with start-ups – we’re built for start-ups
  • Most law firms charge you by the hour – we find ways to serve you with creative and value based fee arrangements
  • Most lawyers love to tell you what they know – we’re here to listen, learn and understand … and then offer you advice to move your idea forward 
  • Most lawyers focus on the law – we focus on your business growth within the law
  • Most law firms measure their success by billable hours and revenues – we measure success by your success
