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.

Our company is creating a very nitch type of app for the pizza industry and we went through 10 plus interviews with app companies. We chose ChopDawg because of their understanding of exactly what we were looking for along with their fair pricing of the job. The team is responsive and makes changes until we are happy. The team’s responsive service, accommodating approach, and timely deliveries make them a strong long-term partner. ChopDawg.com adheres to the budget and vision for the solution.

Before finding Sigma Software, i was reaching out to other App development companies in which i didn't feel confident enough to handle the project. Then i met Sigma, and right away i noticed how easy they are to work with, and how they understand what is needed. They completed my project, but still work on new features I am adding. The developers, project manager, test engineers are all TOP NOTCH and very professional. My future apps will be built by them without hesitation. Thanks guys!
