Not to toot our own horn, but we do (https://circleci.com https://circleci.com). We make Continuous Integration for web apps, and occasionally a customer will have a "works on my machine" bug. I've definitely spent a couple of evenings on the phone helping customers out with this, even though it's clearly not our fault. Every page in our app has a "Help" button, our About page has my phone number on it, our error dialog has a button to contact support. We love when people contact us. To be honest, as much as I enjoy talking to customers, this is just good business, for tons of reasons: - people won't pay if it mysteriously doesn't work, no matter whose fault it is - customer development is essential to a startup, and this creates opportunities to talk to customers (when you're done, have a chat, don't just sign off) - when something is wrong with your service, you have a personal connection to people who want you to succeed - so they tell you the problem instead of letting you accidentally lose customers. - customers with whom you have a personal connection become your biggest advocates. It certainly costs money and time to do this, but I don't think I'm going to regret it.
