Once-cocky start-ups are getting a little self-conscious. In the midst of recent market turbulence, many speculated the IPO market would get tight -- a sky-is-falling cry that hadn't panned out before. But in April, the evidence started to mount, and mount fast.

What with the

feisty unseating of so many glory-seeking Internet companies, high-tech start-ups are growing shy when it comes to the market. As recently as a month ago, IPO bachelors thought a filet-o'-fish sandwich and supersized fries were all it took to charm the markets. But the market has harshly rebuffed their stumbling advances. In April, at least four once-brazen companies quietly snatched their IPO proposals back from the

, and another six companies withdrew follow-on offerings.

Forget about it. Maybe some other time. Gotta go! Bye!

, among others, to keep it warm. "We really didn't need the money," says CEO and founder Jim Carol. "We're very well-funded, our contract flow is good. What do we know? We run the business. Running the business isn't about raising money."

There's no lack of ego here, as the wireless-content market begins to make its first strides. "An IPO is a branding event. The markets were puffed up, for companies like ourselves, valuing companies in the $10 billion to $11 billion range," Carol salivates. "With the aspect of getting that kind of valuation, it makes absolute sense to go public. Once those valuations were gone, it didn't."

Slouching in a decidedly less-attractive market,

Softbank Capital Advisors Fund

. Phew. With its $25 million in new funding, the company could clamp its eyelids shut and forget the harsh judgments of the market.

refused to elaborate on its plans, offering only a written statement about its aborted attempt to raise $55 million through an IPO. "The Registrant believes that terms obtainable in the marketplace at this time are not sufficiently attractive to warrant proceeding with the sale of the Shares," the company said in an SEC filing. So, it huddled with its cooler friends,

Doll Capital

and

Norwest Venture Partners

, and agreed to sit out the IPO this time around. Rest assured, gentle investor, the start-up has "the flexibility to step away from the turbulence of the public market, and will continue to focus on the execution of our business plan."

That plan would be e-commerce revenue from online test-prep courses, plane tickets and merchandise. A little pimply, but the sun shines on a chess club member some days. Right? Right?

went so far as to take a snotty tone. It's not that it couldn't get a date to the prom, it's just that only losers go. In a press release on its IPO withdrawal, OneSoft -- which lost $15.8 million on revenue of $4.6 million in the first three quarters of 1999 -- scoffed that it was waiting because, "The market was having a natural, albeit negative, response to an influx of less-stable technology and dot-com companies."

Once the market stops shooting them dirty looks, we'll see how long it takes to get their confidence back.
