Why CSL?

Space: CSL members enjoy subsidized office space, at a cut cost that makes office space affordable for early startups.

Programming: CSL programming is developed with the specific asks and needs of each cohort, and includes:

• Workshops on the basics of running a business, such as accounting, legal, HR, and digital marketing.
• Guest speakers and AMAs with vanguards of the venture capital and the NYC startup scene.
• Access to the CSL Mentors in Residence ranging from entrepreneurship experts to professors across Columbia University
• Regular opportunities for feedback, such as pitching practice, Product Jams, and problem-solution sessions.

Community: Building a business is easier with the support of others who understand the life of an entrepreneur. At CSL, you get the benefit of being around peers who are taking the same risks, struggling with the same setbacks, celebrating the same wins, and asking the same questions.
