Visible Network Labs is a social enterprise composed of network scientists, evaluators, technologists & communicators using the PARTNER Platform and Methodology (www. partnertool.net). We are committed to helping the world build better, more effective cross-sector, collaborative networks. Inter-organizational Networks are becoming more and more critical way to work in the public and nonprofit sector. Joining with other organizations to share knowledge and resources and coordinate our efforts leads to greater impact and efficiency. However, many networks fail - one study suggests 3 out of 4 cross-sector networks fail to move the needle at all. We help network build a data-driven strategy that guides their collaboration towards greater success and impact.
