INSSIO

INSSIO helps established companies build, modernize, and scale business-critical software. Since 2013, our senior engineers and QA specialists have worked as embedded members of client teams across North America and Western Europe.

We specialize in custom software development, .NET / Azure engineering, IT staff augmentation, QA and Playwright automation, and AI-enabled software solutions.

Our teams work on software that already runs the business - including claims platforms, logistics and maritime systems, energy and billing applications, analytics platforms, and other operational software.

INSSIO is best suited to companies that need additional senior engineering capacity, modernization of existing applications, stronger QA and release confidence, vendor replacement, or long-term technical continuity.

Core technologies include .NET / C#, Microsoft Azure, Angular, TypeScript, SQL Server, Blazor, MAUI, Playwright, OpenAI, and modern AI agent frameworks.

We focus on long-term engineering partnerships, senior-led delivery, direct communication, and deep product knowledge. Several of our client relationships have lasted five to ten years or more.

INSSIO is ISO 27001 certified.
