David Eisenman, founder and partner at Cosmic Charlie, has spent his entire career at independent agencies — including Madwell, the shop he cofounded before this one. About six months ago, he started again from scratch in Brooklyn, this time with a name borrowed from the Grateful Dead and a plan to build the whole operation around AI from day one.
He brought in Elinor Beltrone, partner and head of creative and a former creative director at Ogilvy New York, to give the name a philosophy. The result is an agency that is still pitching, still prospecting and already talking to a brand that only hires indies.
“We’re trying to prove the world wrong,” Eisenman says, “and even our own self doubt.”
For a Brooklyn shop in its first year, that’s a decent place to start.
A Dead song, a dare and a philosophy
Eisenman never saw the Dead with Jerry — too young — but one lyric from “Cosmic Charlie” stuck: “I just wonder if you shouldn’t feel less concerned about the deep unreal.” To him, it reads as a case for meeting an uncertain future with good vibes instead of dread.
Beltrone isn’t a Deadhead, but she built the brand out from there. “Cosmic” stands for infinite possibility — “right now, it’s AI, but tomorrow it’s going to be I don’t know what.” “Charlie” is gender neutral. It’s you and me.
That’s why the agency’s freelancers are called the Charlies. The tagline, “Fearless in the future,” does the rest.
Known for — well, working on it
Six months in, Eisenman won’t pretend Cosmic Charlie has a reputation yet. He knows which one he wants.
“It’s about doing great creative work by humans who embrace the tools that are possible to bring the next level of creativity out there,” he says. The goal is effective work that uses today’s technology without being limited by what it can do today.
Manifesting counts as strategy in year one.
Idea first, a little unhinged
Beltrone’s creative taste is formed by years at big and small New York agencies, and it starts with the concept. Pitches, new business outreach and early client work all get pushed toward ideas that are “a little bit unhinged” — the kind people remember.
The second strength is where AI lives. Not in the creative, Beltrone is clear, but in how the agency runs: operations, timesheets and workflow built from the ground up.
The third is what that buys them — speed. “We work really fast,” she says, “and we can really focus on what really matters, which is the thinking and what our clients need.”
Answering to clients, not shareholders
Eisenman has always seen indies as a counterpoint to the holding companies. In an era of consolidation, he describes the big networks as machines built for the capital markets, where “their primary constituents aren’t their clients; they’re their shareholders.”
Independence means decisions get made on outcomes, not dollars. Clients have noticed.
Brands are seeking Cosmic Charlie out because it’s independent — some got burned before, others want an approach they won’t find at a network. One brand the agency will start working with in the coming months only puts indies on its roster.
The people in the pitch are the people on the work
Cosmic Charlie isn’t chasing big and shiny. Beltrone lights up for scrappy brands, CPG, baby brands and food.
The pitch is simple: the senior people you meet are the senior people doing the work. “When people are pitching, they’re seeing a set of people, and then when it comes to the real people working, they’re gonna see a different set of people,” she says. Here, clients text the partners when there’s a problem.
Eisenman frames it as a veteran team “in an extremely nimble package” — one that can punch above its weight without the bureaucracy. Straight to the source.
Meet the Charlies
Cosmic Charlie runs with four full-time staffers and a bench of Charlies scaled to each project — strategists, designers, creative directors, ECDs. Right now, that includes two junior creatives fresh out of school, freelancing for two weeks before an internship.
Beltrone meets constantly with talent, including the many recently let go. The work is fast-paced new business, with fresh ideas every 24 hours.
Eisenman adds a rare perk: honesty. If you’re not a fit, they’ll tell you why — and offer pointers. For junior talent tossing portfolios into the void, that alone is worth the meeting.
Underdogs with a heavy dose of weirdo
“We definitely feel like underdogs with a heavy dose of weirdos, for sure,” Eisenman says. Nobody expects a new business to succeed, and that’s the fuel — proving themselves more than the next agency.
Beltrone agrees, and adds that they are “very hungry and very nice.” After years of creative-department safety, cold-emailing clients has been a revelation.
“It’s just really interesting to be on the other side,” she says. “I’m enjoying it very much.”
Thank you, Samira. Call us, Polymarket.
Beltrone used her moment for gratitude, thanking mentor and friend Samira Ansari of Grey. “I wouldn’t be where I am now without her,” she says. No client shout-outs — she’d rather let the behind-the-scenes work speak.
Eisenman went prospecting. Top of his list: Polymarket.
“Really cool brand, and I think they’re doing some cool stuff,” he says. “Love to be able to support their marketing.”
The future, as ever, remains unwritten. Cosmic Charlie seems fine with that.
