The economy-driving role of information and communications technology (ICT) firms – large and small, national and global – is growing larger in these early decades of the 21st century, and the potential for impacts is expanding right along with it. This paper looks in particular at the role ICTs have played in serving low-income (base of the pyramid, or BOP) communities over the past decade, and draws some lessons from this broad record of experience with regard to ICTs and future growth prospects, both for the firms themselves and for the economies they serve. Evidence suggests that the time is now ripe for achieving both business and development goals, utilizing what the paper calls "enterprise ICTs" – tools to help small firms to grow bigger more rapidly, and tools to link firms of all sizes more efficiently.
