Ask HN: What are some great examples of well-designed startup websites

I'll start with my favourites:

1. http://heymosaic.com/ 2. https://www.airbnb.com/ 3. https://www.mint.com/ 4. http://beanstalkapp.com/ 5. http://www.newcompany.name/ 6. https://squareup.com/ 7. http://disqus.com/

I have a popular list of great landing pages on Kippt here - https://kippt.com/jg/beautiful-landing-pages

What are your criteria for this? "Beautiful" and "drives conversions" are two different things.

Also lots of threads on Quora by special interest (e.g. https://www.quora.com/Onboarding/What-products-have-the-very...)

My criteria are:

- user experience and information architecture done right

- visual beauty, pixel perfect and modern aesthetics of web user interfaces

Can we think the web page with a visual beauty and lack of call to action?! Would it be a good designed website? I think no. So, well-designed website has all of important aspects, to call users to action.

Thats not what he meant. Ugly sites can convert and do extremely well. Visual beauty (aesthetics) and conversion/UX are not mutually exclusive. Not that it lacks a call to action or any sort.
