NeedlePI

I could only see the needle (after I checked the link and read about it), but I do not see Pi.
Only a mathematician will understand your logo.

This is pretty esoteric stuff. I do see the needle, but do not see PI either. At first blush, the logo looks to be Arabic. I would never pick this out as an IT company. There is a total disconnect...logos are meant to be enlightening and give people an symbolic representation as to what the company does. While the mathematicians my find the use of Buffon's needle clever, it is up to the designer to steer them in a clearer and more defined path. I had never heard of Buffon's Needle...I don't need a logo to make me feel uneducated.

I'm a bit new to this site, but I would think it would be best to start a new critique thread if you change your design. It helps to compare versions, and all the current comments are inapplicable.

With that said, I still do not read this as PI. I don't see the letters, and the symbol reads poorly.

I would lose the gray stroke to emulate depth. It doesn't appear to have a consistent perspective, and doesn't add anything to the logo.

I'm okay with the colors; they seem much better than the last version for sure. Again, I don't have the other version available for comparison, so I only have my memory to go off of.

Be careful of how you're drawing your lines. A simple logo like this relies heavily on how clean and consistent your curves and line widths are. However the idea could use some work. Use a symbol that is easily recognizable by many, and reads clearer (as I pointed out eariler). Much better attempt, but I think we can still reach a stronger solution.

Best of luck.

You have somehow gotten hung up on this circular shape to represent pi. If you can't get them to change the name of the IT company, which isn't likely, then start working from a traditional symbol for PI. You are also going to have to incorporate the name of the company into any logo you design. You are also probably going to have to come up with an explanatory slogan to let people know this is an IT Company.

I am closer to seeing PI here, but it looks more like a script lowercase r now.

I agree with the above. Your looks more like a N than Pi.

Overall, the lack of before hand sketching is flagrant. Stay away from your mouse and sketch a few hundreds ideas first.

I feel that the logo does not clearly clarify the business of your company https://tunnel-rush.io
