Coffee and Donuts Event, May 2017
Our members enjoy the best of both worlds – productive, light-filled office space and opportunities to collaborate and connect with others in the social impact community.


SIF offers a collaborative community and shared work space where mission-driven organizations connect, learn, and grow

As a result of the Social Innovation Forum's acquisition of the Next Mile Project, we manage a collaborative, community space dedicated to helping nonprofits work productively, build their capacity, and broaden their networks to achieve social impact. We strive to build an inclusive community of diverse programs and leaders who engage and grow together.

In addition to basic office amenities, members have access to workshops, trainings, peer-to-peer network building, and other events and activities to connect more deeply with Boston’s philanthropic and social sector leaders.

Our space is conveniently located in downtown Boston, right next to the Haymarket MBTA station and a short walk from Boston City Hall and the State House.

What types of coworking memberships are offered?

At this time, we are offering two levels of membership in our open layout coworking space:

  • Hot desk membership ($275/month) – For people happy to come in and sit somewhere different every day.
  • Dedicated desk membership ($350/month) – For people who would like to have a desk to call their own where they can leave some belongings. (There is also the possibility to block dedicated desks together to create a team space.)

Both memberships include basic office amenities as well as access to workshops, trainings, peer-to-peer network building, and other events and activities to connect more deeply with Boston’s philanthropic and social sector leaders.

Please note: In October 2017 we announced that with generous sponsorship from the Eastern Bank Charitable Foundation, SIF is offering up to six months of subsidized coworking membership to individuals/nonprofit organizations in greater Boston that provide support and promote successful integration and advancement for immigrants, refugees, and asylum-seekers. See more information on that membership here.

People come here because their work is energized and improved by being surrounded by other nonprofit leaders focused on social impact.

What sort of amenities are offered with membership?

We are a small coworking space by nonprofit professionals for nonprofit professionals. Our goal is to provide the space that you need to work productively and the support and community that will allow you to achieve impact.

Office and business amenities:

  • High-speed fiber internet
  • Printing/scanning
