There are innumerable organizations that are working on financial inclusion all around the globe, and there is a lot of innovation in this area of work.
(1) One line of innovation lies in the delivery mechanisms for microfinance : targeting the right set of beneficiaries, figuring out ways to scale up and provide financial assistance to even more beneficiaries, and coming up with more efficient ways to channel the funds from the funding or investing source to the communities themselves.
(2) Another line of innovation lies in the services you provide : providing beneficiaries with skills and vocational training for example, so that they can create more financially viable businesses. Or providing them with support networks, or business development advice.
(3) The final line of innovation lies in the organizational structure of the organizations involved in this area of work. I don't mean innovation as much as diversification. It is no longer just one development agency that is going and providing these funds for example. Instead, new types of collaborative structures are emerging to work in this field. For example, people with different kinds of expertise - finance, business development, policy analysis, economics - are teaming up to create more comprehensive strategies for financial inclusion and to access a broader set of beneficiaries. I have linked to the SEEP Network above; it would be an example of such a collaborative structure.
Through personal contacts or online exploration, I am constantly discovering new organizations that are making some very substantial progress at connecting the world's poor, excluded and marginalized to economic markets.
