An app that lets students know when their school bus will arrive. A toothbrush that won’t wind up in the landfill. A straw that lets you know if your drink has been spiked. A vintage clothing store for plus-size women.

Those were the four winning pitches from Patchogue-Medford High School students who shared $3,750 in prize money in the Patchogue Young Professionals’ and Pat-Med High School’s eighth annual Business Plan Competition. This year’s prizes were provided by The Kiwanis Club of Patchogue.

At least eight teams submitted competitive proposals, but the four winners were notable for the amount of research they did on things like manufacturing costs, product market and competitors.

“You guys stood out the most to us,” Stephen King, a Patchogue Young Professionals co-founder, said during a check presentation ceremony at Pat-Med on Thursday, March 6.

Two teams, Bus Buddy and Pure Smile, tied for first place. Safe Straw took third and Plus Avenue was named Honorable Mention.

Here are the winning proposals:

Bus Buddy (first-place tie) - Ella McCann, Hannah Nuzzo and Gabriella Poirier

The team, all seniors, developed an app that aims to solve some long-standing school transportation issues. For students, it lets them know in real time when their school bus will arrive. For parents and bus drivers,  it lets them see that the child has gotten on the bus and exited the bus at school or home.

School districts would be interested in purchasing such a product, Poirier said.

“I think if we pitched it to the right people, they might find the money for it,” she said.

Pure Smile (first-place tie)- Marilyn Cruz and Juliana Owens

Cruz, a junior, and Owens, a senior, developed a biodegradable alternative to plastic toothbrushes that is “not only good for the environment; it’s good for your teeth,” Owens said.

A replaceable brush head of charcoal-infused bamboo bristles fits on top of an aluminum handle. A built-in holder with biodegradable floss makes it easy for users to remember to floss.

The quality of the team’s presentation caught the eye of Michele Cayea, a Patchogue Young Professional co-founder.

“You ladies are so polished; you’re going places in this world,” she said.

Safe Straw (third place) - Kevin Hidalgo and Luke Loewe

The two seniors developed a product for people worried about someone spiking their drink at a bar: a straw that tests for the presence of any foreign substances in the drink.

Plus Avenue (honorable mention) - Ryan Daly

Daly, a senior and president of Pat-Med’s Fashion Club and secretary of the Business Honor Society, submitted a proposal for a vintage clothing store for plus-size women. She’d locate the store in Woodside, a Queens neighborhood with a lot of foot traffic and access to numerous subway lines and a Long Island Rail Road station.
