I worked with Esthan for about 2 months. They have very good ideas and they always try to follow through with their promises. The problem was that they were constantly changing things and then not answering questions or delivering on expectations. If you want to be involved in something cool and make money doing it as well then this might be a good option. It's also good if you are looking for someone to help grow your business. I am sorry I ended up leaving because I didn't feel like I had much to show for my time there (I did get some good leads but no tangible results). There wasn't anything that stood out negatively. The only thing that comes to mind is they were constantly changing what we were supposed to do. They would send us emails saying "you need to do this now" and when we asked them why we weren't getting any updates after a while they just stopped responding. They promised.
