@nickdemey , Posters are so beautiful. BTW, I was going through your website and saw list of things you offer to corporates. Do you do outbound sales for this ?
Few thoughts :
a) Reach out to funded startups. They will be interested in Lean Start-up Programs and few other programs
b) Reach out to companies hiring for employee engagement. Since they are hiring for employee engagement, it means they are willing to spend money on company's culture.
