New York City has long been known as a hub for finance, ecommerce, and health care startups.
But recent years have seen a rise in another breed of startups tackling issues ranging from crime to housing, sports to beauty.
In many ways, New York has become a hub for diverse companies -- with even more diverse founding teams.
Each year, Business Insider talks to industry insiders and venture capitalists to find some of the most exciting companies in the region. Their nominations, plus some fundraising data from PitchBook, help shape this list of startups to watch. To limit the list, we only included companies founded in the last five years and narrowed it down to startups headquartered within the greater New York City area.
The companies featured range from those that are just getting their start, to some that have already inked major deals and gained national exposure. All of the companies featured seem poised to do big things in the coming year.
Here are the hottest startups in New York to keep your eye on:
What it is: Brooklinen is the brainchild of husband-and-wife duo Vicki and Rich Fulop, a couple based in -- where else -- Brooklyn. The company was founded three years ago and initially sold its wares on Kickstarter.
The premise of Brooklinen is "luxury bedding at non-luxury prices." As an ecommerce site, the company wants to cut out all possible middlemen and avoid brick-and-mortar retail. In doing that, Brooklinen says it eliminates as much as $200 in costs -- its bedding starts at $99, compared to what the company says can be more like $300 at traditional retailers.
Brooklinen now offers plenty of items for the bedroom, including sheets, comforters, pillows, and candles. But it has stuck to just two fabrics: classic percale, and "Luxe," which has a higher thread count.
Founders: Rich and Vicki Fulop

Elysium Health is developing supplements that could prevent aging.
What it is: Elysium Health wants to help people live longer, healthier lives through supplements. Elysium's first product is a supplement called Basis, which aims to boost levels of a specific protein found in cells. The protein, called "nicotinamide adenine dinucleotide" (NAD), may help prevent aging.
The supplements industry can be a tricky one to navigate. Supplements aren't regulated the same way prescription drugs are, which means they don't always contain what they say they do.
But Elysium is trying to change that. The company boasts an impressive board of scientific advisors and presents results of its clinical trials, which are intended to show that the supplement is safe.
Founders: Eric Marcotulli, Dan Alminana, and Leonard Guarente
Funding: Elysium Health has raised a $20 million Series B led General Catalyst and joined by Breyer Capital, Morningside Ventures, and Sound Ventures
Bowery is moving farming indoors.
What it is: Bowery isn't the first startup to venture into the world of urban farming, but it hopes to be the most innovative.
Located about 15 miles outside of New York in Kearny, New Jersey, Bowery grows its plants inside a giant warehouse. Because of that, the company estimates it can grow 100 times more greens per square footthan the average urban farm.
Bowery grows its plants under LEDs instead of sunlight and inside nutrient-rich water beds instead of soil. The startup even has its own operating system, BoweryOS, to change the weather conditions in the warehouse.
Bowery now sells its plants at Whole Foods and Foragers locations in the New York City area.
Founders: Irving Fain, David Golden, and Brian Falther
Funding: $27.5 million from General Catalyst, GGV Capital, GV, First Round Capital, Box Group, Lerer Hippeau Ventures, Tom Colicchio, and others
Citizen helps you avoid crimes in your neighborhood.
What it is: Citizen's goal is to keep you informed of crimes in your area. The app shows you a real-time map of incidents in your area sourced from 9-1-1 calls, and if you're in a quarter-mile radius of an incident, you'll get a push notification.
Users can get real-time updates about ongoing crimes, and watch and upload videos of the incident within the app. Citizen worked with public safety experts, police, and civil rights leaders to get input on how to make the app safe for people to use.
Citizen first launched a year ago as an app called Vigilante. The app quickly went viral, but was pulled from the app store due to safety concerns. Vigilante relaunched in March as Citizen, and has since expanded to San Francisco after a six-month beta test in New York.

Anchor is bringing radio into the digital era.
What it is: Anchor is a platform for recording and uploading audio content, and aims to be the digital-friendly version of radio.
Anchor is a lot like Instagram or Twitter in that it allows users to publish content to anyone who follows their feeds. But it's not about photos, videos, or text -- instead, Anchor is all about your phone's microphone.
The app lets users record up to two minutes of audio, then publish it. Users can reply to posts with their own audio messages, called waves. It's like SoundCloud, but nothing can be pre-recorded, and no recording can be longer than two minutes. People use Anchor for anything from mini stand-up comedy routines to pretending to be characters like Yoda from Star Wars.
Founders: Mike Mignano and Nir Zicherman
Funding: $14.4 million from GV, Accel Partners, Eniac Ventures, CrunchFund, and others

DRL's races feature remote control air crafts that fly at speeds over 90 miles per hour.

But Transfix aims to pull ahead of the pack with its tech savvy and environmentally friendly goal of cutting back on waste. The startup has a high-tech "fleet management system" that lets its customers track their shipments, message with drivers, and calculate fuel taxes. There's also an online marketplace that lets customers have some control over who they're matched with and what they're paying.
Founders: Drew McElroy and Jonathan Salama
Funding: $78.5 million from NEA, Canvas Ventures, Lerer Hippeau Ventures, Bowery Capital, and others
Warp + Weft is an inclusive, low-cost denim brand.
What it is: Warp + Weft -- textile terms for the specific weave in fabrics -- was founded only a few months ago. It's part of a growing trend of direct-to-consumer denim brands, but its focus on inclusivity and reasonable prices are what set it apart.
The startup was founded by veterans of the premium denim industry who noticed a gap in the market: Low-cost, high-quality denim for people of all shapes and sizes. The brand offers jeans in women's sizes 0-24 along with petite sizing, and offers men's denim in sizes 28-40. Warp + Weft's jeans are sold online and all cost under $100.
