During college, Mancini was struggling to pay tuition and was employed as a manager at multiple jobs. One day while he was scraping emails for bulk orders, he discovered that there was no outlets making jerseys for fraternities and sororities. Seeing a gap in the market, Mancini founded Almighty Jerseys to take over the niche. He has been able to grow his business through influencer marketing, greek life pages, social media ads, and collaborating in engagement groups.
Almighty Jerseys has attained the proper licencing to sell their products including NCAA licensing and have recently created NCAA/Greek Life jersey collaborations. Outside of jerseys, Almighty Jerseys offers a variety of apparel for custom greek life designs ranging from long sleeve shirts to flip flops. Mancini has stated that he is committed to building long-term relationships with his clients to give them the best service possible.
