According to PE Week Wire Browster has raised $3.37 million from Vanguard Ventures and Advanced Technology Ventures.

"...Earlier seed backers included John Zeisler of gabriel Venture Partners, Robert Simon of Alta Partners, former Menlo Ventures pro Rick Magnuson and Ken Sawyer of Saints Ventures."

Browster is a nice web preview tool - it helps you to browser quicker through your search results. It previews the homepage in a sperate window and loads the remaining results in the background while you check out the first ones.

It's a nice tool no doubt - but guys $3.37 million with a supposedly even higher $6 million Series A isn't that a bit too much? It's relatively simple to calculate that valuation might have been between $15-$20 million. Considering the expectation of investors to see an interesting ROI Browster should ideally sell in near future for well over $75 million. With a rather normal multiple of 10 this means $7.5 million in revenue.

Now let's assume Browster only uses the click ads, as they do now, with a per click value of $0.30 (all my assumptions) that means a hefty 22.5 million clicks per year. Considering a click through rate of 1 per cent, Browster will have to show 2.250 billion pages per year.

The worlds biggest internet site according to Alexa is is Yahoo. Yahoo has around 70 million page views a day. Yahoo would need roughly 32 days to do what Browster intends to do 365 days. So it will be a quite a leap for Browster, isn't it?
