About John Santiago

I'm a serial entrepreneur with a few successful exits under my belt, turned discerning investor and philanthropist. I’m focused on purpose-driven opportunities.Prior to my latest venture, Sangre, I’d founded and built a few impactful and industry-leading businesses alongside truly brilliant and remarkable people. Most recently, I founded M8, a digital-focused advertising agency that became a global partner for the world's most recognizable brands. I served as CEO until its acquisition by Dentsu, one of the leading global publicly traded advertising agency holding companies, in 2018. Following the acquisition, I was retained by Dentsu as CEO of M8 in addition to the role of Chief Client Officer at Dentsu Creative Americas.At Sangre, I lead a seasoned team dedicated to cultivating early-stage businesses and community-focused investments, accelerating growth and success for diverse founders and their communities through our robust portfolio of built and acquired assets.In 2021, I launched Raised, a 501c3 nonprofit that helps children raised by single parents reach their full potential. Raised helps young adults with career planning, future-proof industry certifications, career connections with the world's leading companies, and assists with housing and childcare expenses to improve the lives of single parents and their young children.
