Brian Weisfeld has been building businesses his entire life. As a kid, he sold gummy bears, nuts, dried fruit, and mix tapes; sorted baseball cards; and babysat.

As an adult, he helped build well-known, billion-dollar companies including IMAX Corporation and Coupons.com.

Brian is the Founder and Chief Squad Officer of The Startup Squad, an initiative dedicated to helping girls reach their potential, whatever their passions. Brian lives in Silicon Valley with his wife and two daughters.

Nicole C. Kear grew up in New York City, where she still lives with her husband, three firecracker kids and a ridiculously fluffy hamster. She's written lots of essays; a memoir, Now I See You, for grownups; and the Fix-It Friends series for kids. She also co-wrote the Startup Squad series with Brian Weisfeld. She has a bunch of fancy, boring diplomas, and one red clown nose from circus school. Seriously.
