On the steps of Union Square in New York City, a group of Dan Fredinburg‘s close friends gathered to share memories of the 33-year-old Google executive, who was killed by an avalanche on Mount Everest this Saturday.

The steps were strewn with flowers, candles and photos from his many adventures.

“It was people who loved Dan gathering to mourn the loss of an incredible person, but also to celebrate an amazing life,” close friend Cristina Gibson tells PEOPLE.

“After Hurricane Sandy, Dan flew to NYC and organized an impromptu volunteer effort on Staten Island called #operationsandcastle to help victims who had lost their homes,” Gibson recalls. “He inspired other people to be the best versions of themselves.”

“He inspired me to be better in so many ways,” Fredinburg’s friend, Juliana Goldman says. “He always saw the best in everyone.”

More tributes for the beloved friend and colleague are popping up online. On Monday, a group of close friends created Live Dan, a campaign and website where people can pledge to live fearlessly “like Dan,” learn more about Fredinburg’s story and donate to the causes he supported.

The page shared a video of Fredinburg outlining his rigorous training regimen – and his sense of humor and adventurous spirit shine through.

A CrowdRise page friends created in Fredinburg’s memory has already raised $65,000 to help children affected by the disaster.

“Dan was on a mission to change the world and do good,” Goldman added. “I think he would be touched that somehow his death could raise awareness for Nepal and all that’s going on right now.”
