(Wall Street Journal) — Grants aren’t for only nonprofits. Small businesses can sometimes get their hands on that money too—and get a big boost in the process. Take Wombat Security Technologies Inc. When it was spun off from Carnegie Mellon University in 2008, the software start-up had seed money from the school but needed more to develop new antiphishing products. So, the Pittsburgh firm turned to the federal Small Business Innovation Research program. Its efforts were rewarded with a number of grants—including a $750,000 award in 2010 and one for $100,000 this year. The grants “can be a tremendous source of funding,” says Norman Sadeh, co-founder and chief executive at Wombat. “It’s a great opportunity.” But identifying and applying for grants requires jumping through some hoops. Here are some tips to help you decide if a grant is right for you and navigate the application process.
