An online concierge service, myEZBZ, is catching fire with some stars of Bravo’s “Real Housewives of New York.”

When RHONY star Sonja Morgan needed to plan a party, she turned to myEZBZ to find a venue, photographer and caterer for the best price.

Erstwhile New York housewife Aviva Drescher uses the site to plan summer activities for her kids, from swimming lessons to art and music camps.

The online concierge service launched in 2011 with $1 million in startup funds and now has more than 750,000 businesses in its network.

“People use it to find anything from contractors to personal trainers — you can even plan a cocktail party in a few minutes,” founder Shana Schlossberg told our Jennifer Gould.
