Twitter raises another large investment; published reports say deal values company at $1B

Something to tweet about: Twitter gets more dough

SAN FRANCISCO — Twitter Inc. has raised $100 million in a deal that values the startup at $1 billion — even though the 3-year-old company still hasn’t generated any meaningful revenue.

CEO Evan Williams didn’t specify dollar figures in a Friday blog posting. But a person with knowledge of the negotiations told The Associated Press of the figures, confirming earlier reports. The person spoke on condition of anonymity because the parties had agreed not to announce the specifics.

Before the most recent round of investment, the San Francisco-based company had already raised $55 million to fuel the operation of one of the Internet’s most popular communication tools. Twitter has attracted 54 million users.
