Alex Shahrestani

Partner
Alex loves to geek out over tech. Video games, his 3D printer, his coding projects, bioengineering, privacy, cybersecurity… Get him started and he will go on and on…

and on…

He also found that he has a knack for brand and IP management. He often looks back on his young, naive belief that he'd find copyright and trademark issues boring, and thinks, "Wow. Was I wrong."

Maggie Shahrestani

Partner
Maggie finds strong women inspiring. Her mother was the first female U.S. Air Force pilot in a combat situation. Her college friends are mostly women in STEM. Some of her best friends run their own startups selling inventions they helped design. She likes to keep up the trend of surrounding herself with powerful, entrepreneurial women.
Maggie especially enjoys helping companies compete with — and do business with — bigger brands, while holding onto the values that make them unique. She loves the thrill of helping a client enter a first big contract, or the satisfaction of putting an empty legal threat to rest.

In The Press

"I saw that there was a thriving startup scene in Austin, which would be perfect for learning about technology law," Shahrestani said. "I ended up attending UT law, but when I got there, no one knew anything about technology law." .... Shahrestani said he couldn't find any resources at UT related to technology law, so he decided to create his own. This led to the beginning of the Journal of Law and Technology at Texas, a student-run journal and organization focused on issues relating to the intersection of technology and law.

Some people believe technology can bridge that gap. "Technology can automate various functions. Whether that's client intake or document drafting and that lets you spend less time on each case and more time serving more people," Shahrestani said.
