Ask HN: What data sources do you report from that helps make business decisions?

For more established start-ups and medium size businesses, I'm wondering what data sources you pull data to determine the health of your company and also help make business decisions. It could be from multiple sources such as Google Analytics, MailChimp, Salesforce, and/or organic KPIs on Excel sheets, etc. Would be great if you can shed light on the reports that you, your executives and/or employees religiously review, and where the data came from. Would it be beneficial to deliver all these data in one unified dashboard or iPhone app?<p>For example, our startup (just a two person shop) mainly looks at<p>-Google Analytics -Some metrics such as "% of active users" pulled from our own db.<p>Manually putting those together isn't overly complicated. But I can imagine larger companies wanting to view large datasets from email campaigns, CRM, and numbers from their transactional databases, etc. Where else do you pull data from?<p>Thanks a lot in advance - let me know what you guys think!
