That $80 million round valued Carta at $800 million post-money. Today鈥檚 newly-announced round was raised with a $1.7 billion post-money valuation. So, the after-capital worth of Carta has more than doubled since December.

Carta鈥檚 new raise is notable in its pace. Raising successive rounds isn鈥檛 unheard of, but raising a nearly four times as much, half a year later, at more than double the price is a surprise. Here鈥檚 Carta鈥檚 capital history:

Carta that the new round was led by and participated in by and (more on another Goldman round here). Several prior investors contributed as well, including Tiger Global (more on them here).

Former Twitter impressario Marc Andreessen will join Carta鈥檚 board, saying in a canned-quote that his firm 鈥渂elieve[s] Carta will change how Wall Street and the financial work operate by transforming private markets.鈥�

Carta, formerly known as eShares, is popular in the startup world as a way to handle options, 409a valuations, and the like.
