Whether we work in cubicles, the C-suite, or a home office, we’re always navigating the people and cultural norms shaping our workday.

Running a presidential campaign is a lot like running a fast-growing startup.

Elizabeth Warren’s campaign staffers are Slacking one another. Bernie Sanders’ staff is dropping files into Dropbox. When it comes to video conferencing calls, Andrew Yang’s campaign prefers Zoom while Beto O’Rourke’s campaign uses both Zoom and UberConference.

Bringing political campaigns into the modern age makes sense, of course. Like a lot of the startups that were early to adopt office tools such as Slack and Trello, US presidential campaigns tend to run lean and work with short timelines. Tech-enabled tools allow teams to move fast while fostering more collaboration among workers.

There are 20 Democrats vying for their party’s nomination and the chance to run against US president Donald Trump in the 2020 election. According to Federal Election Campaign (FEC) filings, their campaigns have spent about $3.2 million on office software so far this year to help them in their efforts. On the Republican side, Trump’s campaign spent $1,205 in the past two quarters on office software tools. A few campaigns, including Joe Biden’s, didn’t list expenses for hot office-software brands.

Quartz looked through the FEC filings covering expenditures from January to June to see what the campaigns are spending on in regards to popular office software. Notably, many of them are using so-called “enterprise” software tools—Slack, DocuSign, Cloudflare, and Zoom—indicating that use of these tools has moved not only outside of Silicon Valley but also the private sector.

Writing software

Google Doc or Microsoft Word? Yang’s campaign has a preference for Microsoft Office, for which it spent $479; Williamson is feeling the love with G Suite, on which her campaign has spent $1,065 this year.

Creative software

Warren, Yang, Booker, Sanders, Delaney, Trump, and Kirsten Gillibrand use Adobe, the maker of software such as Photoshop and Illustrator. Their campaigns collectively spent $7,906 with Adobe this year.

Security

A number of candidates are spending money to help make their internal processes more secure—not the worst idea after what happened to the Democratic National Committee in 2016.

Booker, Sanders, and Williamson spent about $17,000, collectively, on Cloudflare, a web performance and cloud security company.

Office space

While office space is not necessarily software, the lines between the two are starting to blur, thanks to office-space disrupters like WeWork. Both Buttigieg and Warren’s campaigns use WeWork, spending $18,424 and $47,109, respectively, on space from the co-working giant.
