Fortune went hunting on Tuesday for the coolest startup trying to turn sustainability into a business. After hearing the pitches and weighing the potential impact of their ideas, we’ve picked a winner.

And the winner was…Grove!

Grove CEO Gabe Blanchet ended up hitting all the right notes on stage with a four-minute pitch that honed in immediately on what the company does: Help people grow their own fresh healthy food—and what it sells. To achieve that, it sells an aquaponic indoor garden that combines an aquarium filled with fish, LED lights, and a garden bed encased in a bamboo box to grow fresh herbs, veggies, leafy greens, strawberries and other crops.
