Our Story

Peanut butter and jelly.
French fries and milkshakes.
Protein and soda.

Some things just shouldn't work together, but somehow, they do.

What's up, I'm Dalton, and the same goes for me and my best friend Sam. He's the science guy: a Registered Dietitian who runs ultra-marathons and still has six-pack abs in his 30s. I'm the creative one who brings the energy, the "vibes guy," if you will. Always cracking jokes mid-brainstorm and who thinks thawing pizza rolls counts as meal prep. Together, we make an amazing team.

After one too many late-night fast food runs, I finally asked Sam for a little help getting my diet together. His expert advice? More protein, less sugar. Easy enough, until I actually tried some of the protein options out there. Thick, chalky, and made for people who call the gym their "second home"… like, come on dude. I just wanted something quick, easy, and *gasp* dare I say — enjoyable?! So I straight up asked Sam, "Is there any way I can get more protein without having to think about it?"

After plenty of brainstorming, a few questionable ideas, and some oddly delicious homemade experiments, we created ProSo - the world's first Dietitian-formulated, functional beverage that tastes like soda, acts like protein, and doesn't suck.

It just works. Easy.

Try it yourself!

Meet the team

Sam Kramer

Co-founder & CEO

Hey, I’m Sam, a Registered Dietitian with a not-so-secret obsession for Nutrition Science and product innovation. My academic roots are in Exercise Physiology & Sports Nutrition, and I’ve spent the past decade developing better-for-you supplements, and publishing a few nutrition studies along the way. ProSo is where all that passion meets purpose — making protein simple, smart, and actually enjoyable. When I’m not in the lab, you’ll find me running ultra marathons, rock climbing, or doing improv and stand up comedy.

Dalton Anderson

Co-founder & CBO

Howdy, I’m Dalton. As a creative, I’ve worn a lot of hats over the years: shooting photo and video for my favorite restaurants, building brands from scratch, and helping scale a media biz to millions of subscribers. Now I’m bringing that same energy to ProSo, where my mission is simple: make protein FUN! Outside of work, you can catch me playing Runescape, autocrossing my BRZ, or making a fool of myself on stage doing improv comedy.

Hailey Heil

Head of Operations

Hey, I’m Hailey, a Licensed Mental Health Therapist who somehow fell in love with the operational side of running things (yep, spreadsheets can be soothing). I’ve spent the past five years building and managing my own private practice, where wellness isn’t just my work — it’s my lifestyle. You can usually find me at the yoga studio, hiking with friends, or enjoying the Swamp Rabbit Trail.
