Building Social Base


Open Society Initiative for Europe’s call for proposals is open to NGOs registered in the Czech Republic, Hungary, Poland, and Slovakia to support their efforts strengthening their social support base.


The Open Society Initiative for Europe seeks projects that can develop concrete, well-designed, and detailed plans for how the applicants will reach, interact, and involve those people who approve and support their values and goals and who actively receive and deliver their messages. The projects should introduce how the planned activities strengthen public and professional visibility of the applicants—how to increase the number of their supporters, volunteers, and followers on social media. In addition, the projects should contain measurable indicators and the clear expected results and impact. 

Eligibility Criteria

The Open Society Initiative for Europe looks for key civil actors in Czech Republic, Hungary, Poland and Slovakia that have a proven track record of work for open society values and are active in the following professional areas:

  • human rights, including but not restricted to the rights of women, people who are LGBTI, minority populations, and other disadvantaged groups
  • the rule of law
  • anticorruption
  • investigative journalism

Ineligibility Criteria

Any political activities, cooperation with, or support for political parties or elected officials are not eligible for our support, and we will not consider supporting them in any form. Political party-affiliated associations are not eligible to apply for our support.


The Open Society Initiative for Europe aims to support up to eight projects in each eligible country under this call. Applicants may submit one proposal per organization for a one-time nonrenewable grant up to a maximum of $70,000 by following the link to the grantee portal below. The duration of a grant is 24 months. Please make sure to read the detailed call for proposals before applying.

Specific content of the projects is not set: An applicant can design and develop any kind of idea and approach that serves the achievement of the above-listed goals. However, Open Society prefers those projects that connect social base and support building to concrete, measurable indicators. These activities may include but are not limited to increasing and widening the number of members, individual supporters, online followers, and activists as well as volunteers of the organization; increasing the scale and scope of local support and sources from local fundraising; and engaging with new constituencies, including through communication campaigns. Specific attention to different social groups of women and other social minorities and projects that target women’s audiences with customized messaging are particularly welcome.

All interested organizations are invited to participate in a webinar on the Open Society Initiative for Europe’s social support base and constituency building program on 20 May, 2019, 2:00–4:00 p.m. (CET). The webinar combines conceptual and practical sessions and features a Q&A with Open Society and NIOK Foundation staff.
