hiline is the natural evolution of Gardner & Capparelli, our boutique accounting and strategy firm founded in 2016. Our goal with hiline was to push the boundaries of what an accounting firm can be even further. Because too many small and medium-sized businesses with massive growth potential and killer business ideas were held back by details like accounting, taxes, and HR. We wanted to change that.

Today, we’re giving entrepreneurs access to the back-office firepower that their ambitious aspirations call for. Combining our stack of best-in-class cloud accounting technology and our dynamic team of professionals, we’re breaking the conventional accounting firm model to deliver a new, premium experience to clients. The result? We’ve helped business after business achieve their goals faster, grow smarter, and achieve financial peace of mind sooner.
