The main reason is: this is their homepage after they just released a MASSIVE new product and raised a pile of money. The majority of relevant traffic to their homepage either knows who optimizely is or is already a customer. Their original product was pretty straightforward: easy-to-use A/B testing. Put in your site, drag and drop some stuff, click go, and it'll tell you if one version performed better. Their old home page reflected this, and mostly tried to get you to take it for a test drive (you could enter any URL and play around with it). The new product is MUCH more upmarket. They're looking for companies that have enough traffic that you can cut your visitors 5 different ways and still have a meaningful segment to market to. Between this and the fact that it's new news, the homepage is deliberately information-light. They know you know them, and they want to get on the phone. My prediction is they drop back to something a bit more interactive / descriptive once the buzz from their raise and launch dies down.
