"I was on food stamps and pregnant at one point so I had no choice but to make it, and I didn't have education to really fall back on," said Tyrner, who is now 32 years old.
After her daughter's birth, Tyrner left California for a fresh start and took a job in fashion in New York City, working as a brand manager, before turning her attention to the food world.
In 2014, she launched Farmbox, a company that delivers boxes of produce to customers, with a specific eye to two groups of customers: the time-pressed and those in food deserts, areas that lack accessible food that is affordable.
While on food stamps, Tyrner realized how difficult it was to eat healthy food while on a budget. Farmbox's deliveries start at about $39.
The company quickly took off. This year, it's on track to generate more than $5 million in revenue. To date, it has raised a seed round of $450,000 from investors.
But it's been a steep learning curve.
"One of the major struggles for me was I had to really learn how to be a CEO of a national company and to lead others that work for me," she said.
Farmbox currently has 26 employees.
"Your attitude and how you manage people makes or breaks a company," she added.
