Clickable, a service that lets small and medium-sized Web site owners manage their advertising, confirmed it has raised a total of $6 million in a first round of financing.

We reported earlier on the funding, which came in two portions (first here, and then here), but today the company named two more investors we didn’t mention earlier.

Aside from Pequot Ventures and Union Square Ventures, Peter Thiel, former CEO of PayPal, and Jonathan F. Miller, former America Online chairman and chief executive, also invested.
