Our Team


Braintrust’s founders bring a combination of educational bonafides, demonstrated business acumen, and the laser-focused parental insights that come from raising 5 kids between them. Mara and Jen empathize with parents and teachers alike, and have the expertise to cleverly solve the most pressing problems facing educators and the families they support.

Mara Koffmann

Co-Founder and CEO

Mara is a problem solver. She’s spent her entire professional career helping students and families understand and overcome their most difficult learning obstacles. No matter how seemingly intractable the problem, Mara relishes rolling up her sleeves and finding effective – and fun! – solutions that will help students achieve their full potential.

Mara lives in Brooklyn with her husband and two young boys. Because children require playthings, she has temporarily surrendered her love of order and interior design.

Jen Mendelsohn

Co-Founder and CBO

Often described as pathologically gregarious, Jen loves nothing more than quarterbacking a business opportunity. Through life’s challenges, she 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.


Our team members are seasoned, customer-focused business operators. But, more important than our expertise is our empathy — our team members are parents, educators, and dedicated individuals who wake up each day thinking about how to improve the tutoring experience and build a better way.
