Best Web App Development Platforms for Startups

EASA

EASA has a unique approach to deploying existing, Excel spreadsheet-based tools as secure, custom web applications. These apps can be deployed within a web portal for use by internal or external staff, including partners, resellers, suppliers or customers as well as subscription based applications (SaaS). Unlike competing solutions, sophisticated spreadsheets with VBA, macros and add-ins can be deployed with EASA. Furthermore, EASA provides full database functionality, approvals and notifications and integration with CRM and ERP systems. Common use-cases include the deployment of spreadsheets used for CPQ (configure price quote), insurance raters, financial analytics, engineering calculations, and many more. Your existing spreadsheet becomes the “engine” for the web app, eliminating any need to extract the logic and reprogram in a separate solution. If your company has made a significant investment into critical spreadsheets, then learn why AIG, Voya, HP and others rely on EASA.
