Block finally chose a product by eClinicalWorks, a small, privately owned firm in Westborough, Mass. Part of what sold Block on his final choice was the company's customer service. When he called with a question about eClinicalWorks' product, he was transferred not to a functionary but to co-founder Girish Kumar Navani, who told him, "I'm going to stay on the phone with you as long as it takes for you to decide you like eClinicalWorks best."
Founders - answer phones. Answer emails. You're building a company, which means you have to sell it too.
