The prospect of becoming an entrepreneur 鈥渃ame out of left field.” But Lewensztain was determined to build a fruit-first CPG brand of his own. After graduating from medical school, he joined an accelerated MBA program.
Leveraging an MD and MBA to start a business: That’s it.
鈥淚 got a business degree with the intent of utilizing both backgrounds to practice medicine on a grander scale and in a more of a preventative way,鈥 Lewensztain says, 鈥渆specially trying to get kids to develop better habits 鈥 to let them know that they can actually eat things that taste good and are good for you.鈥澛犅
Lewensztain founded his fruit-focused snack brand in 2012. He named the business to encapsulate its simple, few ingredients. A bar with just two (one fruit and a second fruit) became its first and core product.
First, Lewensztain took his bootstrapped brand to farmers markets to see if it had legs. Steady interest was there, and within a few months, That鈥檚 it. submitted for a Whole Foods national rollout program 鈥 and became one of four businesses selected to participate.

Navigating major retail distribution and expansion
The learning curve was steep, demanding astute navigation of manufacturing and supply chain, Lewensztain admits, but the Whole Foods partnership generated significant awareness and landed additional accounts. Soon, That鈥檚 it. hit other major retailers, including Target and Starbucks.
The business continued on its growth trajectory, with a notable inflection during the pandemic when people started paying closer attention to what they were consuming, Lewensztain adds.
Now, in addition to those early retailer partnerships, That鈥檚 it. is available in numerous other stores, including Costco, Sam鈥檚 Club, Walmart, and on American Airlines flights. The brand also sells online through its official website and on Amazon. That鈥檚 it. currently sees more than $100 million in annual revenue.聽
Balancing the business’s scale with sustainable growth
Balancing scale with sustainable growth has always been one of the business’s biggest challenges, Lewensztain notes.
About nine years ago, the business took a small undisclosed amount of capital, but That鈥檚 it. 鈥渧ery consciously鈥 avoided the venture capital route, determined to retain full control over the business and its infrastructure.
鈥淏ecause we’re not venture-backed, we have to even more so really mind every cent and reinvest into the right places to help fuel that growth,鈥 the founder says.
Investing in innovation that aligns with brand goals
Naturally, innovation is a key investment area in the ever-evolving, crowded CPG space. But it鈥檚 not as straightforward as churning out a series of trendy products for the sake of it.
That鈥檚 it.鈥檚 challenge 鈥 and opportunity 鈥 lies in staying true to the heart of its brand when it comes to any product development.
That鈥檚 it.鈥檚 new fiber bar, which introduces added nutritional benefits but keeps fruit center stage, serves as a recent example.

Over the years, amid an increased , Lewensztain鈥檚 received a lot of requests for a protein-packed bar.
However, even feedback that seems well-informed and on the nose isn鈥檛 worth taking if it misses the mark on brand intention. That鈥檚 it.鈥檚 guiding mission was always fruit, going back to Lewensztain鈥檚 medical school days and his initial business inspiration.
Adding protein to the brand鈥檚 flagship fruit bars just didn鈥檛 align with that goal. 鈥淭here are a lot of 鈥妏rotein bars,鈥 Lewensztain says. 鈥淭here wasn’t a need for another one to enter the category.鈥澛
A focus on fiber that doesn’t miss the mark
Instead, That鈥檚 it. turned its attention to a bar with a focus on fiber (an ingredient enjoying popularity amid , a trending term encouraging people to increase their fiber intake), which naturally occurs in fruit.
鈥淲e’ve elevated the amount of fiber, all from fruits, which is a very big distinction compared to fiber ingredients that are extracted and then added back,鈥 Lewensztain explains. 鈥淚t’s much easier on the body and comes with a lot better benefits in terms of health and wellness.鈥
Another recent addition to the product line-up is Fruitola, a snack blend featuring fiber from fruit and protein from plants. 鈥淲e don鈥檛 like to copycat,鈥 Lewensztain says. 鈥淲e like to bring newness to the market.鈥
To that end, fruit-forward simplicity in snacks remains the brand鈥檚 overarching goal.
鈥淲e served 250 million servings of fruit last year,鈥 Lewensztain notes. 鈥淥ur target is over 350 million this year, and we’re even tacking on a billion grams of fiber as well.鈥

Staying true to the original mission and meeting demand
Even with its expanded line today, That鈥檚 it.鈥檚 products still have anywhere from one to five ingredients, which is fairly unusual across CPG brands, Lewensztain adds.聽
The founder is proud the business hasn鈥檛 strayed from its original mission and sees even more potential ahead, as more consumers, especially among younger generations, seek transparent products with minimal ingredients.
鈥溾奣hey want cleaner, healthier, better for you,鈥 Lewensztain says. 鈥淲e’ve always been that. We never had to change; we never had to remove anything. That鈥檚 kind of that medical background kicking in, but that was really the idea all along for us.鈥
