## About

INSSIO helps established companies stabilize, modernize, and scale business-critical software.

We work with CTOs and engineering leaders who need additional senior engineering capacity, stronger software delivery, or a reliable alternative to an underperforming vendor. Our engineers and QA specialists embed directly into client teams and work on software that already runs the business - from claims and logistics platforms to maritime operations, billing systems, analytics tools, and other operational applications.

Our core expertise includes custom software development, IT staff augmentation, QA and test automation, and AI-enabled software solutions.

Core technologies include .NET / C#, Angular, Azure, Blazor, MAUI, SQL Server, Playwright, and modern AI technologies including Generative AI and AI agents.

Unlike short-term project shops, we focus on long-term engineering partnerships. Our teams build deep system and business knowledge and often remain embedded with clients for years.

Why companies choose INSSIO:

- 12+ years serving clients across North America and Western Europe
- Client relationships lasting 5–10+ years
- Senior-led engineering and QA delivery
- Direct access to engineers and company lead
- ISO 27001 certified
- Strong .NET / Azure specialization
- Manual QA and Playwright automation integrated into delivery

INSSIO is best suited to established companies with software already in production and a real need for modernization, additional engineering capacity, improved release quality, vendor replacement, or long-term technical continuity.
