From shoveling snow to producing records to founding tech companies, Calvin Williams is a born entrepreneur. Now, the president of IISE’s Atlanta professional chapter has built Impruver.com, a strategy execution and improvement software. Williams talks with IISE’s Michael Hughes about going from the rock bottom of eviction notices to success, how race has driven him often to focus on creativity over capital, why fitness beats lean as a corporate goal, and his dream of giving back even more to underserved minority communities.
