"So in everything, do to others what you would have them do to you" (Matthew 7:12, NIV). We believe in treating people with respect and earning trust, because this is how we wish to be treated. We believe in honesty, respect, and being above reproach in all areas including programming, design, billing, and client relations.


Quality is a certain almost intangible aspect of a product that instantly lets you know it was made with care and is built to last. It's like the difference between a cheap shirt, and one made with precision and durable material. We build software that is designed to be low maintenance, enduring, and secure.


Software is often too complicated. We firmly believe that the measure of a product is not just the sum of its features, but also the parts that were intentionally left out. Simple design is not easy, but we take the time to analyze our code, interfaces, and every aspect of our company to ensure simplicity.
