We chatted with with Nicolas, founder of BBQ Croc ($40K/month). In our interview, Nicolas says:
The more you interact with others (retailers, consumers, etc.) the more things can happen. Never slow down or stop or give up. If the product is good and you fight, many things can happen when you least expect it.
What I have learned so far is that designing the product was the easy part. Getting it in stores and into the consumers hands was the real challenge.
