I'm the self-funding founder of Willowfinch and have been working with Lunarbyte for nearly 3 years. My app is a data intelligence app and so not quite as simple as a sales site. The algorithms are complex and other developers / orgs had quite a difficult time grasping the innerworkings. They have consistently worked within my limited budget and advised me on best practices. While I coded the back-end algorithms on the cloud platform & architecture I'm comfortable with, they accommodated that & created a seamless experience. Their pricing is reasonable and they work very hard to give me accurate quotes for work so we can prioritize. I love working with them.

Overall experience with New Normal has been great. We started building an application for our new business in 2018 and have used them ever since because of their flexibility, and the "partnership" we've forged. Our company is still too small to manage/create/hire an internal software development dept, so NN continues to fit the bill.
