Mission: take the stress and confusion out of buying and selling houses Unlike many real estate agencies, this one does not use MLS (Multiple Property Listings). And it charges only 2% from realtors and homebuyers instead of typical 5 or 6%. Moreover, it pays the agent salaries, instead of working with them as contractors. So how does it use AI?To replace agents. The company tracks users who clicked the ads and their behavior on the website. Then, it shows the ads according to their interests. Smart algorithms also analyze the data about homeowner history to find out their buying capabilities. Computers are better at processing big loads of data, but REX still hires 22 people to guide users through the sales process.
