Don't feel bad about it. Always do what makes sense for your business. If you can handle doing it manual, do it. There will be a point where you are growing too much and too fast, and you loose too much time deploying, then look for implementing CI. A lot of people will tell you to use CI from the start. And our startup has been using CI since the beginning, but there was no apparent benefit in the start. It was only 1 full time developer, and a second part time. Right now we couldn't live without it, but this is because our applications has grown considerably, and the speed at what we are implementing our ideas is fast. Loosing time doing Deployment and running tests manually would be a great loss of time and of flow. CI is only worth it, if there is a benefit for your project.
