I applied to their retail division that they had with Simon (larger mall real estate company) but didn't get asked to pitch. I believe they have like 3 different divisions if I'm not mistaken: Retail, fintech and IOT.
Yea they definitely aren't as popular as YC or techstars but they have a pretty impressive portfolio on startups they invested in. I like the fact that they have industry specific programs. I can only speak for the retail program because that's the one I applied to but they invite executives from the largest retailers around and get a chance to network and close sales.
