Jen Mendelsohn is co-founder of Braintrust, an online marketplace connecting parents with certified teachers. She has often been described as pathologically gregarious and loves quarterbacking a business opportunity. Through life's challenges, Jen became that expert mom — the one who everyone turns to for a great recommendation — but she hopes that Braintrust will amplify access to everyone and become an even greater connector. Jen is a proud Soho resident and on most days tolerates her husband and three children. They remind her (somewhat ironically) that she is an impatient teacher.
