How social entrepreneurship can become social innovation has been little studied, even less in the rural context. This document poses that social entrepreneurship generate different types of capital as they integrate into a social network, and it is that social capital that allows it to become a successful social innovation. Applying a social capital approach to two social enterprises (or social entrepreneurship) study cases, from Colombian rural communities victims of armed conflict, shows how social enterprises integrated into social networks achieve two significant outcomes. On one side, generate interactive and collective learning and institutional change, and on other, favour determinants of social innovation, thus incrementing and reconfiguring social entrepreneurs' capabilities leading to social innovation.
