READ WRITE - Nov 11 - If you want to succeed today, you need to put your product out on the market, collect user feedback and keep tweaking it to make sure you've got a winner. To do that, you need to attract early adopters, people who will sample your product or service and tell you what they think. The problem is finding them. Erli Bird is working to solve that problem. Erli Bird is a website where beta users can discover new startups, try their products and give feedback. Erli Bird has a freemium option that connects your startup with around 100 beta users for free. You can connect with more for a fee. Erli Bird launched in June and now has 70 startups participating. They include Glyder, an iPhone app for small businesses built by a Zynga designer and an OpenTable cofounder, and Capriza, which lets users make their own mobile apps in less than three minutes.
