Looking for startups to participate in an article

Hiya, Hopefully this is the right forum for this question, but I am looking for startups (or suggestions of startups I could approach), who would be willing to share data for an upcoming article on conversion stats. Essentially I am looking for startups who: 1. Have an account creation requirement before you can start using them 2. Have a direct revenue model (no advertising) Our startup (www.eventarc.com) is an example of this, and we will be sharing our data in the article. Specifically I am looking at conversion rates, so at no stage will we be sharing revenue numbers, customer numbers or website visits. What is in it for you? 1. Serious link love 2. Serious promotion opportunity - we anticipate this will be a popular article, and it will be seeded across the web (including here on Hacker News). 3. A warm feeling in your heart that you are helping other startups by sharing data! We already have 5 international startups agreed to participate, including at least 1 big name that you would all know and use. I am looking for at least 3 more, but happy to include others. Do you know any likely candidates I could approach, or do you run a startup who would like to participate? Please let me know! I can share more detail via email if you need it. Please note at this stage we are just after expressions of interest, but if we do ask you to share your data then we will definitely include you in the article. To get in touch for more info, email me at scott at eventarc dot com. Thanks, Scott.
