" Real-estate sites had some tough times last week. First, Redfin, an online brokerage for residential real estate, announced that it was laying off 20 percent of its staff, then Zillow, a service that delivers home values and lists sales, announced that it was forced to lay off 25 percent of its workforce.

But Trulia, which lets buyers find homes for sale across the United States, says it has no layoff plans and that it has enjoyed so much growth, it's actually looking to expand.

"We are not making any layoffs. All companies need to be smart in this environment and adjust to the market movements," Pete Flint, CEO and co-founder of Trulia, said in an interview. "As a company, we are in a strong position. We always believed that we had to be aggressive but fiscally responsible, and that is why we are in the position we are (in) today. In fact, we are still making a few select hires, where they are important to our revenue growth."
