Over the years, he has employed at least 500 people and prides himself on nurturing his staff and producing future leaders.

Prior to Spire Digital, Gellman founded his first company, GIG Media, in 1996. GIG was one of the nation’s first interactive agencies. Prior to GIG Media, he served as a writer and producer for television and film with companies including Troma Pictures and The Teaching Learning Network. He also performed stand-up comedy and had small acting roles in productions throughout New York City. And, he was one of the web’s earliest bloggers, publishing his musings online for a daily audience of more than 10,000 readers three years before the term “blog” was coined.

Gellman earned a bachelor’s degree in English from the University of Florida in 1994.

David Maren

As Spire’s Executive Vice President of Strategy (EVP), David helps clients find answers to burning questions: Whom should we build for? What pain points should we target? What are the gaps in our portfolio? Where is the bathroom? Etcetera.

A true intrepreneur, David has spent over 20 years helping products, brands and businesses grow. Back in the mid-1990s, he was part of the team at Celestial Seasonings that brought green tea to the mainstream. Following that, he helped the organic food movement reach the tipping point. His move into the digital realm began just over 12 years ago, having dreamed up a SaaS startup for nonprofits with backing from his alma mater, Oxford University. Before long, his journey into the software world led to high-profile consulting engagements with the likes of Boeing and Wells Fargo, in support of their own digital transformation efforts. Along the way, he also helped a fledgling smart-home brand navigate their way to success.

David’s penchant for wayfinding extends to his spare time. He enjoys serving as a mountain-bike guide for Spire clients in search of magical trails to ride in the forests above town. He’s also been known to host clients and ideations in his mountain yurt, which was recently featured in The Wall Street Journal (paywall version | free version on WSJ’s real estate site). Located in a stand of towering pines in a place aptly called Evergreen, the yurt is open year round thanks to a Norwegian gas stove, and accessed via ziplines that run high above any snow.

She also serves on the board of Women In Digital as Speaker Chair. Ayla has lived in rural China, southern France, and on a boat in the Caribbean.

She also has the pleasure of tackling culture-y, fun stuff like team outings and internal yoga classes – namaste.

When she’s not busy being the office DJ and “practically a developer”, she enjoys checking out new yoga studios, doing all things outdoorsy, seeing what concoctions she can come up with using whatever’s in the fridge, petting dogs, live music, talking about finding people new jobs, and memes.
