Mixbook, a provider of customizable photo books, cards and calendars, has been honored as one of Forbes’ America’s Most Promising Companies for 2013 – a list of one hundred privately held, high-growth companies with bright futures.

Founded in 2006 by Andrew Laffoon and Aryk Grosz, Mixbook is featured in the February 11, 2013 edition of Forbes Magazine as one of “The Nifty 50.” The complete list, along with videos featuring Laffoon and other honorees at Aileron Entrepreneurial Institute, is now available on Forbes.com.

“We’re thrilled to be recognized by Forbes,” said Andrew Laffoon, Mixbook CEO/Co-Founder, who was also chosen as one of America’s Most Promising CEOs under 35. “It certainly reinforces the Mixbook vision and our mission to completely redefine the photo book, card and calendar making experience. From our website to new iPhone app, Mosaic, we continue to empower our customers to create tangible, permanent memories from their photos.”

For the Most Promising list, Forbes strove for a holistic gauge of young, privately-held companies, trying to pin down their trajectories by looking at a slew of variables. Over the course of six months Forbes reviewed thousands of applications. The final assessment is based on growth (both in sales and hiring), quality of management team and investors, margins, market size and key partnerships.

Forbes turned to CB Insights, a Manhattan-based data research firm that specializes in assessing private companies, to refine the search. Their software scans 45,000 sources to measure a company’s health. A new distribution deal, for example, marks a positive signal, while the loss of an executive is a negative. The software gathers those myriad signals into a final score that Forbes uses as an initial guide in producing the list. After verifying sales numbers, speaking with each company and debating their merits and blemishes, Forbes produces a final ranking.
