CEO and founder, Sarah Flint, believes in style without sacrifice. She built her brand, founded in 2013, with the goal of creating original luxury shoes made with the finest materials and craftsmanship that also fit and feel amazing. After addressing the issues with wearability in luxury fashion footwear, Sarah wanted to make her shoes accessible to more women, so she took her brand direct to consumer, avoiding the traditional 6x retail mark up and offering luxury quality at half the price of department stores. Sarah Flint’s shoes are made with fit and function in mind for women who are out in the world with places to be and things to accomplish. Her designs embody the ethos of the brand that has been held since the beginning - a woman should never have to sacrifice feeling good for looking good. It is Sarah’s dream to make women feel empowered and at ease, one pair of shoes at a time. Since launching her eponymous brand, Sarah Flint has seen a flood of celebrity and influencer love with marquee fans including Meghan Markle, who has been seen in the shoes over 30 times, Amal Clooney, Lady Gaga, Kristen Stewart, Blake Lively and many others. The brand also has celebrity investors most notably, Cindy Crawford, who is a marketing partner and mentor to Sarah. As a direct to consumer brand, Sarah Flint has experienced explosive growth and has emerged as a leading digitally native luxury brand.

We take our cues from nature to mimic the physical properties of vegetables. We’re developing biomimetic hydrogel therapies for obesity and other chronic metabolic diseases. In April 2019, Gelesis received FDA clearance for its lead product candidate, Plenity®, as an aid for weight management in overweight and obese adults with a Body Mass Index (BMI) of 25-40 kg/m², when used in conjunction with diet and exercise. Plenity is contraindicated in patients who are pregnant or are allergic to cellulose, citric acid, sodium stearyl fumarate, gelatin, or titanium dioxide. The most common side effects were diarrhea, distended abdomen, infrequent bowel movements, and flatulence. Plenity is currently available in limited release in the U.S. Gelesis’ proprietary approach inspired to structurally mimic vegetables is designed to act mechanically in the GI pathway to potentially alter the course of certain chronic diseases. In addition to Plenity, Gelesis is developing additional investigational candidates such as Gelesis200, a hydrogel optimized for weight loss and glycemic control in patients with type 2 diabetes and prediabetes. This biomimetic hydrogel based on the Gelesis platform technology are also being advanced in other GI inflammatory conditions, such as non-alcoholic steatohepatitis (NASH) and functional constipation.
