As technology advances, new companies and industries rise up, offering unique solutions, services, and products. Not every new tech company makes for a promising investment though. Startup companies are especially risky to invest in because there’s no telling how they’ll perform. Before gauging how well a company can do, it’s important to see how well it has done in the past.
