Ask HN: Founders and CEOs: What do you use for early-day BI?

Hi all, I am doing some market research, and I would be interested in surveying the tools that starting companies employ to do BI (if any). By BI, I mean to include analyses / reports / dashboards about: - number of users / segments - feature usage - marketing campaigns - market research - sales numbers - financial situation - engineering progress - other kpi that would make sense? I would be very interested to talk with people who would want to make more data-informed decisions, but who did not find a satisfying way to do this. If you find yourself in that situation, please contact me at etienne[at]leap.la I am an engineer with 12+ yr experience making productivity-focused financial data analysis tools and I am building a product to help tech-savvy executives do BI well and fast. Thanks a lot to those of you who kindly take the time to answer.
