Salesforce CEO Marc Benioff and Twitter and Square CEO Jack Dorsey both appear to have donated to a GoFundMe page supporting a proposed Navigation Center. The center would open on a parking lot owned by the Port of San Francisco and add 200 beds for the local homeless population in addition to providing housing and health services, according to CBS' Bay Area affiliate .

Benioff and Dorsey butted heads on a proposal last year aimed at combating San Francisco's homelessness problem. Benioff aggressively supported Proposition C, widely known as a "homelessness tax" on businesses with more than $50 million in annual revenue. The proposition, which will subject Benioff's own business to increased taxes, passed in November despite intense opposition from other tech leaders. Dorsey was among the most vocal critics of the tax, saying it would unfairly affect financial services companies like his own, Square.

But now, the two are on the same side in supporting the new Navigation Center. They are joined by other tech leaders, including GitHub CEO Nat Friedman and Twilio CEO Jeff Lawson, who each appear to have donated $10,000 on the GoFundMe page "SAFER Embarcadero for ALL." GoFundMe even donated $5,000 to the initiative.

A spokesperson for Salesforce pointed to Benioff's tweet Friday, explaining his support for the initiative.

"Homelessness is our number [one] crisis and it requires all of our attention and resources," he wrote.

Lawson also tweeted his support for the campaign, saying, "This isn't about the money, it's about the soul of our city, fighting for our most vulnerable citizens." A spokesperson confirmed his donation.

In a statement, a GoFundMe spokesperson said its donation was part of its "Gives Back" program, where employees nominate campaigns to which they want the company to donate.
