Daniel Jhin Yoo is a former special education teacher and district administrator who co-founded Goalbook in 2011 to help educators transform instruction for students with disabilities before becoming a venture investor at Long Term Impact. His unusual career path from classroom teacher to district leader to software engineer to founder gives him a deeper understanding of educator workflows and special education needs than most venture investors who come from finance or generic tech backgrounds.
