Braze and contact automation

Hi everyone, our company uses Braze as marketing automation/email campaign tool and I’m trying to figure out how to connect our Gainsight to Braze to update lists on Braze (to create flawless onboarding and re-engagement campaigns, see more insights/analytics etc) 

Braze is in product list of Make but Gainsight is not and the opposite for Zapier - Gainsight is part of Zapier and Braze is not. 

Wondering anyone solved this chicken-egg dilemma? Thank you!
