Chattanooga based Variable Inc has a pretty cool product to share with the masses.
It's called the Node, invented by former NASA engineer Dr. George Yu.
The company's COO Greg Compton explains how it works.
"What makes it really special is we can plug it into the node base platform, any type of module. Be it a thermometer or a weather station...or a color station...barcode reader. And the sky's really just the limit," Compton said.
The node works sort of like a videogame controller with smartphones or tablets to give them capabilities like never before.
The 18 month old company now wants to make the Node more noticeable to consumers.
That's why they entered WalMart's Get on the Shelf competition, a contest for entrepreneurs to get WalMart to sell their products.
"So we just submitted an entry via Youtube and we got a lot of votes from a lot of the youtubers out there and I guess Wal Mart saw something special and invited us to be one of the 20 finalists in the competition," said Compton.
Compton says winning the competition would help their company thrive and give more consumers access to their state of the art product.
"For a small company based right here in Chattanooga, making our products right here in Chattanooga right here in this building. It's a tremendous opportunity to have access to the massive sales volume that could come from being a partner and vendor to WalMart," said Compton.
