Growing Strong Celebrating the growing power of women's businesses, Entrepreneur and the Women Presidents' Organization teamed up to bring you the top 50 fastest-growing women-led companies. Meet our No.1 fastest-growing entrepreneur and find out how we chose our top 50.

Exceeding expectations is Amy Langer's business. When she and partner John Folkestad, 40, first wrote the business plan for Salo LLC, a senior-level finance and accounting staffing company, they anticipated sales of about $9 million by their third year in business--no small feat. "Most of our advisors [told us], 'These projections are unreal. No small business does this,'" recalls Langer, 35. "We hit $9 million after two years."

Through her background in staffing, Langer discovered a need in the marketplace to supply companies with top accounting and finance talent. Meeting that need triggered explosive growth for Salo, which launched in 2002. By 2006, sales hit $32.1 million, with 2007 projections of over $40 million. Attracting top-notch talent for outside contractors and her own staff is key to managing the company's astronomical growth, she says. Langer surrounds herself with people who are not only exceptional at what they do, but who also complement her skill set and help take the company to the next level. "I know where I'm strong, and I know where I definitely need people to help me," she says.

As the mother of three small children, Langer faces a big challenge that many working women do: balancing an entrepreneurial life with a life at home. "Wanting to be everywhere has been and always [will] be a challenge," she says. Knowing where to put her focus and how to delegate her time has helped her juggle all her responsibilities. She adds, "If I'm required to be in the office 80 hours a week or else the business can't run, then the business isn't sustainable."
