Charities need innovative equipment.
Companies have marketing budgets.

We connect the two.

We build an invention, deploy it with a charity, and film the journey. The companies who fund it get the story, media, press coverage, and proof of real-world ESG impact. The charity gets the invention for free.

We work with purpose-driven companies:

What companies get.

We produce films, shortform videos, photography, and written case-studies - everything you need to showcase how you enabled the good-cause mission.

Our stories also get coverage across industry publications and mainstream media. See more

A note from our founders

Billions are spent on performative marketing stunts every year. That funding rarely makes a positive impact.

We think this is stupid, so we’ve built Tandem to fix it. Brands fund real work for causes that deserve it. The content that comes back is extraordinary because the story underneath it is true.

Brands get brilliant marketing material.

Good causes get inventions for free.

We get to build ridiculous things.

Everyone wins. ”
