Qurb Gets a Step Up From Second-Time Entrepreneurs

When I first met up with the team at Qurb (pronounced "curb"), I have to admit that I didn't think the world needed another anti-spam product. Not that the spam problem has been fundamentally and finally solved. But with dozens of products and services in the market, it simply seemed an improbable bet for an aspiring start-up. This start-up, though, was different.

I'd first met the founders in 1997 when they were just building what was to become AvantGo. Felix Lin, Linus Upson, and Dave Moore were among the very first entrepreneurs to see opportunity in the emerging Palm economy. Their product, which enabled Web sites to deliver content to Palm devices, became widely used and AvantGo rode the Bubble to a successful IPO.

The AvantGo experience has paid off mightily as Qurb seeks to win the day in the anti-spam category. Not insignificantly, the success of the AvantGo IPO has enabled the trio to finance Qurb without institutional venture capital. (Few things make VCs more interested in a deal than telling them you don't need their money. When I checked in with Upson last week, he told me the company regularly turns away cold-calling VCs.) According to Upson, the company is ahead of plan and on track to be cash-flow positive by the end of the year.

That financial success is supported by a product that is meeting with critical success with the media and with customers. PC Magazine recently named Qurb its Editor's Choice in side-by-side testing of anti-spam software. And the Qurb team finds that it is able to go in behind Brightmail implementations to sell the Qurb client software as part of a "belt and suspenders" approach to spam fighting.

The AvantGo experience has no doubt also helped Qurb to move quickly. In just 9 months, the 1.0 product has been localized to 10 languages to reach global customers. The software uses a sender-verifying white list technique to instantly stop 100 percent of unwanted mail before it hits your in box. Qurb is further designed to protect against domain spoofing that has allowed malicious spammers to masquerade as legitimate senders. It's this latter feature that has helped Qurb leverage content providers as distributors of the software.
The company has found willing affiliates in content providers who want to protect their brands and demonstrate good email citizenship by providing an anti-spam solution to their readers. The benefit to Qurb: significant distribution. The benefit to content providers (many of whom were customer relationships forged at AvantGo): assure their mail reaches their customers and get a commission on each sale in the process.

Today, Qurb introduced Qurb 2.0, which is tightly integrated with Outlook and Outlook Express (the latter being no small feat and a unique selling proposition for the software). The Outlook Express compatibility is the saving grace for the not-so-small army of POP mail services, and opens up tremendous distribution opportunities with ISPs. The clean integration makes the product near-fool-proof for even novice users. The new version is available for a 30-day free trial at . After the trial, the online purchase price is just $29.95.

I wish QURB had a version to use in THUNDERBIRD. I have
it in Outlook Express, but miss it anti-spam qualities.
If you know of one, Please inform where to download.
Thank you

Although I loved this product initially, I have noticed an increase in the spam received since using Qurb which makes me suspect the company may be sending spam out through second parties to confirm the need of its product in the end user's mind.

Yes, QURB for Thunderbird! It's the only reason I haven't switched to Thunderbird but MS won't be continuing OE.
