IT Services and IT Consulting Lewes, Delaware 201–500 employees Founded 2015 Privately Held

AppSierra is a 201–500-person software testing and product development firm headquartered in Lewes, Delaware, with a second operations base in India. The tech stack spans Microsoft cloud (Power Apps, Power Automate, Azure functions/storage), Apache streaming (Kafka, Spark), and front-end frameworks (React, ASP.NET MVC), while active hiring in engineering (71 roles) and data (16 roles) outpaces sales and marketing — a pattern typical of delivery-led service firms scaling technical capacity. Current projects center on platform migrations, SAP implementations (Central Finance, S/4HANA), and event-stream infrastructure, aligned with stated pain points around ETL optimization and real-time data processing.
