Thanks for your submissions! I really like your designs. #2, #3, and #4 look good, but I'm concerned the infinity sign for the 'og' looks more like 'ag' at quick glance. #6, #7, #8, #9, #10, #11, #12, and #13 are great logos, and I love that you're going with an icon, but I'm not sure the icon fits the business. Could you try going a more science theme with the icon? Perkology - The Science of Perks (i.e. Biology, Mixology). Let me know if you have any questions about that.
