First Round Capital blog, “Reflections & Lessons Learned from Roblox, After More Than a Decade of Partnership,” by Chris Fralic (First Round Board Partner), accessed July 2026. https://www.firstround.com/news/reflections-and-lessons-learned-from-roblox-after-more-than-a-decade-of-partnership — First Round’s own recap of its Roblox partnership. Confirms that First Round initially passed on investing in late 2007 when the game was “really early and very basic” at a valuation “close to $10M,” but reconsidered in July 2009 after monitoring metric growth (revenue from ~$15K to ~$220K/month; David Baszucki iterating to version 87 of the business model). Amount and valuation of the July 2009 investment are not stated directly in this post but are provided in third-party analysis (see 16). ↩

Jermaine Brown, “First Round Capital Recaps One of Its Best Investments,” accessed July 2026. https://www.jermainebrown.org/posts/first-round-capital-recaps-one-of-its-best-investments — Independent analysis referencing First Round’s own communications: First Round wrote a $500K check at a $14M post-money valuation in the July 2009 seed (six months after passing on a $10M valuation in early 2009). Also documents May 2011 follow-on ($3M at $40M val — the Series D-1/D-2 round). The July 2009 round was issued as Series D preferred stock per the Roblox S-1 registration statement (54,859,430 Series D shares authorized). Total round size $2.2M per multiple aggregator sources (Tracxn, Crunchbase). The prior Roblox “Series C” of $2.9M closed in January 2008 per the same S-1 preferred stock schedule. ↩↩
