Does that make DreamIt ventures automatically a great option? No. I think everyone who looked at the website noticed the spelling/grammatical errors, nebulous role descriptions, and laughable testimonials. Their 15,000 bucks may not be the same as 15,000 from YC but they seem to be a legitimate option. At the very least they are a "safety" incubator to YC one would think.
