I see businesses (and churches) all the time that are small yet they try to play big ball (huge marketing campaigns, etc) when their strengths are relational community and viral word of mouth. It is okay to be who you are. Be a point guard. Exploit your nimbleness and lack of bureaucracy for quicker reactions and doing more intimate relationships than a 6’11” company would ever consider.
Example: Offer a personal handwritten thank you card to every customer with a small appreciation gift included and 3 business cards for referral.
A great article on why you can play small ball and win.
