NumFOCUS Accomplishments in 2017

2017 has been an incredible year for NumFOCUS! Here’s a quick list of highlights to date:

We can’t wait to expand upon our success this year for an even more exciting 2018! But to do that, we need your help…


NumFOCUS is excited to participate in “Giving Tuesday” (Nov. 28th) this year, just after the U.S. Thanksgiving holiday. Inspired by Black Friday and Cyber Monday, #GivingTuesday calls on the public to invest in charity instead of consumerism.

We’re throwing a “friendraiser” in an effort to grow our overall membership, and we need your help!

What’s a Friendraiser?

We’re asking our community of supporters to reach out to your friends and colleagues and invite them to become a member of NumFOCUS. (Curious if you’re already a NumFOCUS Member? Check for your name at the bottom of the page here.)

Rather than focusing on a specific fundraising goal, our #GivingTuesday friendraiser is focused on signing up as many new Community, Supporting, and Sustaining Members as possible.

How Does Membership Help NumFOCUS Projects?

From Netflix to NASA, researchers use NumFOCUS tools to solve the most challenging problems. Support the open source projects that power innovation and discovery by becoming a NumFOCUS Member this #GivingTuesday.

NumFOCUS provides a stable, independent, and professional home for projects in the open source scientific data stack. We help provide funding, operational services, and expertise to support long term sustainability for critical scientific computing tools.

Donations from NumFOCUS Members go towards providing direct support to the open source software projects that you use and love.

This year, donations from Members supported development work including the first SymPy release since 1.0, full Python 3 support for MDAnalysis, an h5py backend for PyTables, and more. (Details on our blog.)

Become a Member

Get Involved

Helping out is easy! First, create a “friendraising” page. Then reach out to your friends & colleagues who use and love NumFOCUS projects and ask them to become a Member (make a donation via your page).

The more Members we have, the stronger our projects are, and the more stable and sustainable they will be over the long term!

You can also form or join a team and friendraise together. Compete against other teams to sign up the most new members — have fun with it!

We’re here to help: reach out to info[at] with questions.


Thank you for supporting open source scientific computing!
