For companies that are showing traction, we often ask founders to share their key KPIs (key performance indicators) so we can get to know what the business drivers are. The team at @versiononevc recently open-sourced a sample dashboard for marketplace products that is AWESOME.
Highly recommend teams building in this segment to take a look and reference for your own products. Looking at your numbers in a simple time series, esp. week-on-week or month-on-month can do wonders on measuring performance.
