Unique Squared, a music gear ecommerce company, has raised $1 million in venture backing, according to an SEC filing. The Atlanta-based company launched operations out of its founder’s basement in 2007 with a $6,000 investment and hit profitability later that year. Founders Paul D’Arrigo, Eugenio Fernandez and Richard Scalesse invested all of its profits back into the company.

Fast forward to 2011, and the company had $40 million in sales, according to a Music Trades magazine estimate. That figure ranks it the No. 12 supplier of music equipment in the world. Unique Squared also reported 2,461 percent three-year growth in the Inc. 500 ranking last year.

The company is applying the content and commerce idea to music equipment, with hundreds of videos demo-ing various pieces of music technology, recording techniques, and other how-to’s. Unique Squared competes on price and offers a loyalty and daily deals programs as well.
