It used to be that American Muslims who wanted a halal meal had to live in a major city and know a good butcher. Want to find an eligible spouse? Get your parents involved. In the market for halal cosmetics? Good luck.

Times are changing though.

Across the U.S., the Muslim population is booming. It's expected to reach six million in 15 years, more than double its current number. That's good news for Muslim entrepreneurs looking to reach the new generation of tech-savvy Muslim consumers. Matchmaking apps like Salaam Swipe provide a twist on Tinder for Muslim millennials. Other companies supply everything from vegan halal soaps to gourmet halal meals delivered fresh to your door.

At the annual convention for Islamic Society of North America this year, community leaders gather to discuss urgent topics like Syrian refugees and civil rights. The event also serves as a venue for marketers to pitch their products. Alongside old standbys like halal chicken distributors and Islamic finance firms, startups are making a bigger show than they have in past years.

Among those startup marketers is Sarah Ahmed. She hands out blue plastic cups that say "Share a home with friendly Muslims" to promote Umma Spot. Umma means community in Arabic, and Ahmed says the business is "basically like an Airbnb for Muslims." It connects Muslim homeowners with travelers who want to book short-term stays where it's comfortable to eat halal or wear a hijab.

"It was actually a group of us friends just sitting together after a birthday party one day, and then we were like 'Hey, that would be a good idea!'" Ahmed recalls. "And then we took it and ran with it." Umma Spot CEO Usman Choudhry says the startup, which also plans to help Muslims network, is still in the testing phase and plans to roll out a mobile app later this year."

There's a familiar immigrant story to these startups, says Sahiba Ansari, a representative from the American Muslim Consumer Consortium (an industry group supporting Muslim entrepreneurs). "I definitely do see us following us the trend of the Jewish and Hispanic market," she says: A tech-savvy generation moving far beyond the old neighborhood and the corner stores their parents and grandparents built and relied on.

Ansari's group hosts a "Shark Tank" style contest for startups. Last year's winner was LaunchGood, a company that does online crowdfunding for projects and business ventures with social missions. She estimates the American Muslim market at close to 100 billion dollars.

"It's the American dream at work," says Benjamin Jones, a professor of entrepreneurship and emerging markets at Northwestern University's Kellogg School of Management. "And entrepreneurship of course is an important part of that process."
