B-Lab 2024

B-Lab is an intensive 8-week accelerator program that supports student entrepreneurs developing high-impact ventures. We are welcoming 11 ventures that address unmet needs in a wide range of market sectors: a plus-size women’s shoe company, better-fitting prosthetics, shareable community vacuums, empowering women’s Afghan craftsmanship and fashion, and many more. 

The venture founders from Brown University and RISD bring diverse perspectives, strengths, and interests to the cohort. They are bound together by their passion for creating meaningful solutions to important challenges in exciting markets, and they represent some of the most advanced ventures in the Brown entrepreneurial ecosystem.

Althia Prosthetics

Over 600,000 below-the-knee prosthetic users in the US use an uncomfortable prosthetic socket. An uncomfortable and poor fitting prosthetic socket can lead to pain, rashes, and even infection, causing more trips to the hospital. Part of the reason why this is the case is because an amputee’s residual limb (the part that fits into the socket) fluctuates in volume throughout the day. The majority of current sockets are rigid, with a few adjustable options which are tedious for the user.

Althia Prosthetics aims to solve this issue by creating an automatically adjustable prosthetic to create a better fit for prosthetic leg users.

No Empty Seats 

No Empty Seats (NES) is a student-led mental health initiative dedicated to destigmatizing mental illness and bringing an end to suicide. This summer we plan on expanding NES through our clothing brand, college videos promoting mental health, diverse collaborations, and vulnerable shared stories. We acknowledge how crucial it is to speak up about mental health, and we believe that NES is a perfect way to help our peers internalize that it is okay not to be okay!
