Poll: Does your startup try to write secure software?
Please, also keep in mind that even if your startup doesn't process users' private information (such as financial data or email), your website/application could still be hacked to distribute malware, either exploiting users' browsers or inserting trojans to be downloaded.
For instance, I browse sites I trust with javascript and flash enabled in Noscript, increasing the surface attack.
Also, users are taught to avoid only untrusted websites/applications - and they could blindly trust your startup downloading trojans.
