Advertising technology startup Clickable has raised another $3 million from its lead investors Union Square Ventures and Pequot Ventures, in a follow-on round to the $3 million it raised last July, confirms CEO David Kidder. He is calling it an A-1 round. Former CEO Jonathan Miller has also joined Clickable’s board, a fact we reported back in September during TechCrunch40, where Clickable launched.

Velocity Investment Group, the tech buyout fund Miller recently started with Ross Levinsohn, is not an investor in Clickable. The startup is developing Web-based ad campaign management tools.

Update: Peter Thiel and Jonathan Miller are understood to have participated personally in the round as well.
