Our Story

Founded in 2016, JSL  was built on a simple observation: most small and mid-sized businesses were being sold either a website with no marketing behind it or marketing that pointed to a website that couldn't convert. JSL was structured to handle both, allowing the same team to make design decisions and set search strategy rather than negotiating between vendors - an approach that shows up in every aspect of how JSL works.
