Awesome internet / web lawyer -- best I've found!
I would highly recommend Lior Leser for his services as a lawyer. I did a lot of searching, talked to quick a few lawyers, asked a ton of questions, etc. before settling with Lior for my internet and software related legal questions and needs. Whether it be a simple terms of service, a buyers agreement, a private contractor agreement, internet related legal questions/concerns, cease and desist, etc. -- Lior seemed to be the most knowledgeable with reasonable rates as well. The other lawyers I talked to didn't seem to really know a lot of the answers to the questions I was asking (I had easy questions as well as ones that I knew weren't so easy), and when I did ask a question prior to hiring anyone, most of the other lawyers seemed to not want to answer anything until they were hired. Lior was the only one to really help out extensively before, proved his knowledge, etc.. After hiring him, I found his rates to be reasonable, he always got back to me with questions in a timely manner, and was knowledgeable in a variety of legal areas. I would recommend him to anyone looking for a lawyer who specializes in internet law and compliance!

Painfree Website Terms of Service
I used Lior Leser (Web 2.0 Lawyer) to create a terms of service and a privacy policy for a website I founded last year. It was a great experience. He asked me questions to try to understand the purpose of the site and how users would interact with it. He helped me understand the legal risks involved and answered all the questions I had. With a few revisions I was able to get the documents I needed to feel confident in launching my new site.

Endorse Lior
Intellectual property Attorney | Dec 21
Relationship: Worked together on matter
"I commend Lior for being honest, thorough, and organized. If he advises you to pursue a matter, it is worth it. There are plenty of opportunities to "trick" clients: it takes an honest person, and a knowledgeable person, to advise clients correctly on when to pursue a matter and when to let it go. Take it from fellow attorney in the community: this is a hard worker you want to hire."
Contracts and agreements Attorney | Nov 07
Relationship: Fellow lawyer in community
"I have had the pleasure of working with Lior and can attest that he is an extremely good thinker with a highly developed set of legal skills. A dedicated advocate for his clients, I highly recommend him."
Securities offerings Attorney | Sep 17

He is a very good legal advisor to have on your corporate team."
