Box Build
Essential Box Build
One of the biggest challenges for Ronin, especially being a growing company, was keeping overhead costs low while still producing a quality end product and keeping up with the level of demand Ronin was seeing for its product.
By partnering with CA, the Ronin Team was able to focus their time and resources on in-house design and marketing for existing products as well as work on prototyping new ideas. Ronin is reaping the benefits of partnering with a company that had pre-established assembly lines, QA processes, and manufacturing expertise.
