For a while, Aditya Banerjee tried the Cal freshmen thing.\u00a0<\/p>\n

He went where his friends did: squeezing into packed crowds along frat row, shoulder to shoulder with other Cal students hoping to get into parties at houses like Sigma Chi and Tau Kappa Epsilon. He went to big campus events too, the kind that sent students flooding across Sproul Plaza and Memorial Glade clad in navy and gold.\u00a0<\/p>\n

But he never truly found his footing in the everyday college scene. Campus clubs didn\u2019t interest him. Frat parties bored him. Events barely held his attention.\u00a0<\/p>\n

So, what did the UC Berkeley neuroscience and nutrition major do for fun? Make protein bars in his dorm kitchen.\u00a0<\/p>\n

For hours, the 18-year-old would hover over the shared stove in Towle Hall, tinkering with protein, sweeteners and binders in pursuit of the tastiest protein bar he could craft. What started as a dorm-room experiment eventually grew into Posana<\/a>, a protein bar company with products inspired by international flavors.\u00a0<\/p>\n

Banerjee\u2019s protein bar venture comes at a time when, across the country, companies and restaurants are cashing in on the \u201cproteinmaxxing\u201d trend<\/a>, where consumers focus on maximizing their protein intake to boost metabolism, build muscle and manage weight. Consumers are upping their protein intake in various ways \u2014 from shakes, to Costco rotisserie chickens, and even mashed potatoes<\/a>. Banerjee\u2019s quest to craft delicious protein bars stems from his own weight loss journey, and his personal frustration with the limited selection of specialty protein sources offered at grocery stores. As Banerjee puts it \u2014 protein bars are boring, so he aims to change that.\u00a0<\/p>\n

\u201cSo we see a lot of the same chocolate chip cookie dough, peanut butter, and not enough representation of other cultures and their flavors, and that\u2019s what initially made me start the brand,\u201d Banerjee said. \u201cThe whole goal of Posana is to make protein exciting to eat and also flavorful in regards to other cultures and their flavors, apart from America.\u201d\u00a0<\/p>\n

Banerjee, now 20, knew that to start Posana and get his protein bars into grocery stores, he needed some monetary muscle.\u00a0<\/p>\n

\u201cIt was just about how do I really get this thing off the ground, and how do I make it into an actual product that I can sell, right? So it was about doing that research and then doing research on the market. So what I soon realized is that my product wasn\u2019t shelf stable. So even though I had a good base recipe, I knew I had to work with food scientists in that regard, and that\u2019s where money starts coming into play.\u201d\u00a0<\/p>\n

So, in true start-up fashion, Banerjee invested $10,000 from his own college fund, a risky move that he said had his parents worried. Then he turned to his community, looking to his wealthier peers at Cal, and local investors in the Berkeley area.\u00a0<\/p>\n

\u201cI took the money from my college savings account and then put some money into the brand, which my parents did not like,\u201d Banerjee said. \u201cLet\u2019s just say my parents definitely feel a lot better for sure. Like in the beginning, it was very worrisome for them, but I think like right now, in this current state, they\u2019re definitely feeling a lot better and they\u2019re definitely a little bit more supportive, which is great because they\u2019ve seen what\u2019s happened.\u201d\u00a0<\/p>\n

After dipping into his college savings, Banerjee decided to double down on his venture. In May, he took a leave of absence from Berkeley to pursue Posana full-time, a decision that wasn\u2019t easy for someone raised in a Bengali household where education was paramount. But as Posana grew, balancing Berkeley\u2019s rigorous academics with a company was becoming increasingly difficult.\u00a0<\/p>\n

\u201cI always knew in the back of my head that I\u2019m probably going to have to take a break at a certain point, right? Just for the sake of me and then the brand as well, like how much momentum we have going for ourselves,\u201d Banerjee said. \u201cYeah, I mean, it was definitely not an easy decision. I grew up in an immigrant Indian household, and the more obvious thing is this doesn\u2019t usually happen with Indian families and their kids. So I would say the last few months have definitely been pretty rough when it comes to things like me, my parents, our dynamic, the business. What am I really focusing on? What am I really doing?\u201d\u00a0<\/p>\n

Since then, Banerjee has been going to trade shows and traveling across the country to places like Los Angeles, Denver, and New York City to pitch Posana to angel investors, or high net-worth individuals who invest personal funds into start-up companies. But at 20, even traveling for work comes with its own set of obstacles. In general, Banerjee can\u2019t rent a car or book a hotel room, so he\u2019s relied on friends and investors for places to stay along the way. He describes it as \u201cnomadding,\u201d or bouncing between couches as he moves from one trade show or pitch meeting to the next.\u00a0<\/p>\n

\u201cI\u2019ve been nomadding since May, actually. So ever since my Berkeley apartment lease ended I\u2019ve been staying with either investors or my friends,\u201d Banerjee said. \u201cI\u2019m just very lucky. I have investors and good friends that live around the country and they understand my situation. \u201c\u00a0<\/p>\n

The hustle is starting to pay off, expanding his network and bringing him face-to-face with investors who have previously backed companies like Ollipop and Skims. Currently, Banerjee has raised $650,000 from investors. Banerjee has two production factories, one in Los Angeles and the other in Chicago, but keeps his operation remarkably small. Banerjee is Posana\u2019s only full-time employee, working alongside a handful of paid high school and college interns to get the company off the ground.\u00a0<\/p>\n

But at the heart of his brand is flavor. Drawing from his South Asian heritage and market trends, Banerjee wanted to create protein bars that people would reach for, with flavors familiar enough to be approachable, yet unique enough to stand out from the usual crowd. Currently, Posana has three flavors in its lineup: cinnavanilla, mango coconut turmeric, and matcha latte.\u00a0<\/p>\n

\u201cSo one thing that I really look for is are people loving it, how long is it going to last for, and is it really going to be outstanding?\u201d Banerjee said.\u00a0<\/p>\n

For Banerjee, matcha checked all of the boxes: it\u2019s familiar, popular and, most importantly, it\u2019s here to stay. Banerjee points to its growing presence on coffee shop menus and grocery store aisles as a sign of the flavor\u2019s staying power.\u00a0<\/p>\n

\u201cSo for matcha, for example, if you look at every coffee shop now, they carry a matcha latte, right? Or they start to add it to their menu in some regard, and that shows that people are getting used to these flavors, Banerjee explained.\u00a0<\/p>\n

His cinnavanilla is a playful combo that centers the familiar, pairing two approachable flavors together in a combo that Banerjee feels is both fun to eat and say, while his mango turmeric reflects Posana\u2019s broader mission, leaning into the sweetness of mango and coconut and pairing it up with turmeric, an ingredient rooted in South Asian culture.\u00a0<\/p>\n

Banerjee is already thinking beyond his current lineup as he plans for Posana\u2019s next flavor to be a Thai-inspired bar, set to debut this fall. A chai-flavored protein bar is also in the works, with Banerjee hinting that there are more global flavors he plans to introduce to the protein bar market.\u00a0<\/p>\n

\u201cThere\u2019s a lot of really cool flavors, especially from Asia, for example, that are growing really fast in the U.S and we definitely want to be the ones showcasing those flavors,\u201d Banerjee said.\u00a0<\/p>\n

Now, Banerjee\u2019s protein bars can be found in over 150 locations in and around the Bay Area, including places like Monterey Market on Hopkins Street, Berkeley Bowl, Farmer Joe\u2019s Marketplace in Oakland and Luke\u2019s Local in San Francisco. Posana protein bars can also be found in stores across Southern California and New York. Come winter, Banerjee plans on taking Posana further, as he\u2019s in talks with a distributor which may bring Posana to more shops across the Bay Area, including in the San Francisco International Airport.\u00a0<\/p>\n

\u201cSo that\u2019s when it\u2019s gonna be very exciting because after the distributors come on board and they obviously like distribute the product for us, we\u2019re gonna be everywhere in the bay, including SFO,\u201d Banerjee said.\u00a0<\/p>\n

Banerjee has also teased that he is in talks with a major grocery store chain, which could grow Posana on a national scale. But even as Banerjee looks to get Posana onto shelves across the country, his ethos is the same: make protein more exciting.\u00a0<\/p>\n

\u201cThe whole reason why I started this brand is because every American, especially ones who love global favors, should enjoy protein and eat it on a daily basis and that\u2019s my goal,\u201d Banerjee said. \u201cBecause we want to get as many Americans eating protein again. If you can feel that connection, and enjoy it as much as I love making it, that\u2019s all I really care about.\u201d<\/p>\n
