We raised $600k coming out of YC S11 demo day for the classroom lecture tool. We kept costs low, and paid ourselves just enough to live on for ~2 years (plus servers, shared apartment doubled as office, etc.) We burned down to about $80k in cash (~3-4 months runway, not recommended) about 6 months after the launch of analytics.js, and then raised $2m (June 2013).
